Glue for wallpaper joints: reasons for divergence of joints, compositions used, necessary tools and procedure for performing work

Glue for wallpaper joints can be purchased at any hardware store. One of the main problems when gluing wallpaper is the so-called bubbles. The only thing that can compete in this title with the collected air bubbles under the canvas are the joints, which strive to separate. More than once, the next day after repairs, wallpaper has to be glued at the joints. What is being done wrong? And how to adjust the wallpaper when gluing it so that these problems definitely do not arise?

Features of butt wallpapering

This method of joining fabrics is one of the most difficult and in some situations requires some experience.
In its absence, you need to practice. Peculiarities:

• The advantage of such joining is the ability to obtain a uniform coating that will not have visible seams. This imposes certain restrictions on the gluing process: it is necessary to eliminate the smallest gaps and excess glue.
• In addition to smoothing tools (different devices are used for different types of wallpaper), a rubber roller with a soft roller is used.
• Great importance is attached to the preparation of the walls. They must be smooth and free of defects. If work is carried out on geometrically complex surfaces, then end-to-end fitting will require much more time.
• Any violations of technology and the choice of unsuitable material lead to the appearance of gaps or peeling at the joints.

It is necessary to glue wallpaper in this way while strictly observing the optimal temperature and humidity levels. Drafts and the use of heating equipment should be avoided.

Peculiarities

Wallpaper seam glue is fundamentally different from other varieties. Its main features:

• does not require dilution with water – ready for use immediately;
• Convenient to apply thanks to the special spout on the tube;
• has a viscous consistency and does not flow;
• after drying, it does not dissolve with water, withstands temperature changes and high humidity;
• almost instantly grabs the edges and holds them securely;
• suitable for joining wallpaper seams, eliminating defects, gluing sheets in hard-to-reach places (niches, near window sills, behind radiators, etc.).

It is distinguished from traditional means by the presence of a polyvinyl acetate emulsion in its composition. It is this that provides the seam with strength and a short setting period. Construction PVA, which some continue to use the old fashioned way, is inferior in all respects and has not been used in professional repairs for a long time.

The main secret of high-quality wallpapering without visible seams is to quickly and reliably fix the joints.

Wall decoration with wallpaper

In order for your room to delight you with a feeling of warmth and comfort for many years, you need to know how to glue paper-based vinyl wallpaper.

From numerous reviews about the technique of pasting walls, it follows that you need to accurately follow all the recommendations for working with this material, as well as take into account useful tips on the most important stages of the process.

Selecting wallpaper and glue

First, purchase wallpaper and glue recommended by the manufacturer for this type of finishing material. On the packaging you will find the necessary information on the use of vinyl wallpaper, as well as data on glue consumption. Sales consultants, more often than other gluing products, recommend using KLEO for vinyl wallpaper.

Preparing walls for pasting

Walls for pasting must be smooth and dry. Their leveling is done with putty after they have been cleaned of the old coating. Before gluing, the wall must be treated with a primer, as well as a composition that protects the surface from mold that appears under the wallpaper.

To work you will need a tool, which is a set of the following items:

• bucket for clean water;
• basin for wallpaper;
• two pressure rollers and a special plastic spatula. The wide roller is the main one, but for the joints you will need a narrow one;
• fur roller, wide and narrow brushes. The latter is used to apply glue;
• scissors, tape measure, ruler, pencil and knife (construction knife);
• rag, sponge (for removing glue).

Before starting work, the floor is covered with newspapers or polyethylene.

Procedure for covering walls with vinyl wallpaper

If you follow all the rules for decorating walls with trellises, then the room after renovation will have an impeccable appearance. Each stage of repair can be performed even by an inexperienced performer, but he is required to follow the gluing technology and be careful in his actions:

Vinyl wallpapers with a paper backing cannot be glued to the wall after applying glue, but need to be folded back to back for swelling. Usually the waiting time is indicated on the roll (thicker material will take longer); It is imperative to ensure that the applied layer of glue is uniform and thick (the swelling time of the glue will be the same for all canvases)

For trellises with a paper “backing”, it is important to treat the edges of the canvas well with glue; the strips must be glued starting from the corner, end-to-end (the place of contact should not be very tight to prevent “swelling” of the material). When gluing, the canvas is pressed against the wall with a rubber roller, carefully smoothing the seams; you need to glue, focusing on the vertical elements of the interior (window and door openings, corners of the room), but not plumb; gluing is done by two people

The first worker, standing on a stepladder, carefully presses the upper end of the canvas to the wall. The second one, standing on the floor, should support its lower end and carefully align the wallpaper vertically. You can and even need to draw a vertical line on the wall for reference; the strip is pressed against the wall and the air is forced out from under it, quickly moving the brush downwards and from the center to the edges; excess glue may protrude beyond the edges of the canvas, so it is immediately removed with a clean rag. The main thing is that there are no marks left on the front surface of the material; Existing excess parts of vinyl wallpaper near the ceiling and at the baseboards are cut off with a sharp construction knife, and their lower end is folded under the baseboard (about 5 mm). Experts recommend removing the baseboard before gluing the walls; All sockets and switches are removed after disconnecting the power. The wallpaper is pasted, covering its holes, and then, when the canvas has dried, the necessary sections are cut out and screwed into place.

Gluing wallpaper in the inner corners of walls is especially difficult when you don’t have the skills. Often wrinkles appear in these places, which you can try to remove by smoothing. Small defects can be eliminated this way. If it doesn’t work out this way, then make one cut with a knife along the entire length of the fold and very carefully straighten the canvas until it fits completely against the wall.

Why does wallpaper peel off at the joints?

There may be several reasons, let's look at each of them.

Poorly prepared surface

Before you start wallpapering, you need to properly prepare the base. It is especially necessary to approach this seriously if the trellises are thin and smooth. It is necessary to remove the old coating from the surface and evaluate the base. Read how to quickly remove paper wallpaper from different surfaces.

If there are unevenness or cracks, they should be puttied. Prime the surface with wallpaper primer, for example UNIS. If the base is well prepared, then you can use a primer with glue.

Wallpaper glue

One of the important aspects is the correctly selected adhesive composition. For each type of wallpaper there is a specific type. You shouldn’t skimp on glue; it’s better to have a little left over than not enough.

Dilute the adhesive mass only strictly according to the instructions on the package. Do not do this by eye, as you will violate the proportion that implies 100% adhesive ability.

The technology of wallpapering is not followed

We coat the wallpaper with a base on paper with glue, more generously along the edges, since when you fold them for impregnation, the edges “dry out” a little, which is why the wallpaper peels off at the joints.

If the trellises are on non-woven fabric, then only apply the adhesive to the wall. After fixing the canvas on the wall, leveling it, smoothing it, go over the edges of the canvas again with a brush with adhesive mass, and only then smooth it completely. This will to some extent allow the joints to stick well.

Drying conditions for pasted wallpaper

Moisture evaporating from the adhesive mass creates increased humidity, which ensures the technologically specified drying period. The recommended air temperature for wallpapering is +23 degrees. All these factors will ensure high-quality gluing of the trellises to the surface and prevent them from peeling off at the seams.

Unseen circumstances

An emergency situation may also arise when your upstairs neighbors flood you. If the exposure to water is prolonged, and it comes from a hot tap, then you will not be envied, as I know this from my own experience. In this case, the wallpaper at the joints actually peels off, and maybe even the trellises themselves.

We were all at work, and when the water flooded the two floors below me, the neighbors called. Water flowed from all the openings of the chandeliers, passing through the voids of the floor slabs, getting into almost all the rooms of the apartment, dripping from the ceiling, flowing along the walls. The emergency service turned off the water and turned off the lights in the apartment for three days to allow the moisture to evaporate.

The wallpaper was almost undamaged, but in some places it peeled off and the seams came apart to a minimum in the hallway. But the ceilings were all damaged. A small digression, but on topic. Such an unforeseen picture may occur, but this is an emergency scenario and rarely happens. Go ahead.

What should you do if the wallpaper has already peeled off at the seams, you ask. If the fact already exists, then we will try to correct the situation.

How to glue seams at joints and corners that are broken?

The main problem why wallpaper peels off is that working with it seems simple.
They start it without knowing the subtleties and rules. The recommendations are as follows:

• Do not skimp on finishing materials and try not to buy discounted goods.
• Before starting work, read the instructions.
• Use special spatulas and rollers.
• Have a supply of clean cloth napkins.
• Buy good wallpaper glue and a special one for joints.
• Carry out high-quality preparation of the base.
• Carry out gluing before the start of the heating season. It is advisable that the papered walls dry out in natural conditions.
• After repairs, you cannot ventilate the room to prevent drafts.

How to glue wallpaper at the joints if they have come apart at the seams

To complete the work, you need a pencil, a container in which the glue will be mixed, and a roller. Carrying out this work requires extreme care.

To properly eliminate the problem, it is necessary to moisten the damaged surface with a spray bottle. This is done so that the wallpaper does not tear during work. As soon as the paper absorbs moisture, it is necessary to tighten the softened edges of the sheets. The panels that have lagged behind the wall are carefully moved away from it. The problem area is carefully coated with wallpaper glue from the inside. Cardboard is placed over the joint. A stream of hot air is applied to this area for twenty seconds. To do this, use a hair dryer. Then the cardboard should be quickly removed until it is glued. This area should be treated with a wallpaper roller and wiped with a damp cloth.

It is required to use glue correctly. If it is applied in larger quantities, then when drying the wallpaper will narrow, and the adhesive will not be able to dry. According to the rules, the glue should dry first, and then the wallpaper. A poor connection may visually appear when wallpaper is applied as a result of their defect, when they are slightly different in shade. Therefore, before starting work, all wallpaper should be carefully checked for quality.

You need to be extremely careful when working with textile or non-woven wallpaper so that the adhesive does not get on the front part. In this case, when drying, stains will be visible, no matter how hard you try to remove them.

Recommendations for use

Gluing wallpaper joints is best done from a small stepladder that can be easily rearranged. In addition, the following tools will be needed for the job:

• construction knife;
• narrow metal spatula;
• thin brush;
• a spray bottle with water and a damp cloth;
• a piece of hard material measuring 20x30 cm (cardboard or other);
• special roller for rolling wallpaper;
• construction hairdryer.

The joints are glued, sequentially moving from one section to another. If the wallpaper has already been glued before, the damaged area is first moistened with water from a spray bottle and given time to soak a little. Then the edge of the canvas is separated from the wall with a metal spatula and then proceed according to the standard scheme.

How to use glue for wallpaper joints?

1. Carefully coat the inside edges of the panels with glue. It is best to use a thin paint or art brush for this purpose.
2. Place cardboard or another hard sheet over the coated area so that it overlaps both sheets.
3. Press the cardboard firmly and smoothly move the turned on heat gun towards the joint. Warm up the treated area for 20 seconds.
4. Remove the cardboard before it sticks and roll the surface with a roller.
5. Wipe the treated area with a damp, soft cloth to remove any remaining adhesive. Do not press on the wallpaper to avoid damaging the pattern or design.
6. Treat all problem areas in the room in a similar manner.

So, glue for gluing wallpaper joints is very helpful when using heavy panels, uneven walls or a draft in the room. It allows you to glue delicate wallpaper that stretches when wet. It can be used to eliminate defects in the form of loose pieces. All types of joint adhesives are suitable for non-woven, vinyl, fabric and paper wallpapers. This line of products is produced by many companies. But it is better to give preference to well-known manufacturers: Metylan, Kleo, Moment. The choice between them is a matter of taste and material capabilities.

Features of Axton glue

This glue for wallpaper joints, the price of which is 188 rubles, is a mixture used to firmly and quickly fix the edges of the wallpaper if they have separated after repair. The mixture contains special additives that prevent the glue from spreading after its application. It sets in a short period of time, which is very convenient if the material has to be glued in hard-to-reach places.

This adhesive for wallpaper joints, which has only positive reviews, comes in a tube, so it is completely ready for use. Its quantity will be enough to treat an area of ​​10 m2. The composition is resistant to moisture and is suitable for all types of wallpaper. Its ingredients include acrylic polymers and additives.

The wallpaper came apart when glued end to end

A trivial problem typical of paper-based canvases. The gluing of such canvases is carried out by applying glue twice: on the wall and on the canvas. When coating wallpaper, the paper becomes saturated with moisture and swells. In this case, the width of the canvas lengthens by about 0.5-2 mm. After gluing to the wall, the glue dries, and the reverse process occurs with the material - shrinkage. The wallpaper pulls together and forms a sad gap.

There is only one conclusion - do not glue paper-backed wallpaper end-to-end unless the manufacturer specifies this in the instructions. Rolled panels on a paper basis are made with an overlap. However, if you make it large, then after drying the seams will be visible on the wall. To avoid this result, keep the overlap to a minimum of 1-1.5 mm.

Features of joining wallpaper with a pattern in the corners

With a geometric design, its distortion should be minimal. On wallpaper with vertical lines, the distortion in the corners will be pronounced. With a horizontal pattern, the distortion in relation to the ceiling and baseboard will be noticeable and the overlap of the canvases will be more pronounced.

To avoid such troubles you should:

• make a slight overlap on the adjacent wall;
• transfer the resulting curvature to the upper part and hide it behind the panels;
• try to glue the wallpaper in the corners so that the smooth edge lies plumb, remove excess material with a knife.

By adhering to the following recommendations, you will be able to minimize the curvature of the pattern and join the wallpaper correctly. Even if there is a flaw, it will remain invisible to ignorant people.

Various customization options

If there is a pattern on the wallpaper, then you should be prepared to match it when applying it to the walls. There are several ways to match wallpaper and adjust the pattern.

Direct docking

For the convenience of gluing wallpaper using this method, it is important to correctly calculate the length of the strips for further adjustment. This is done according to the following algorithm:

1. The wall is measured in length and height. We record the results obtained, for example, the width of the wall is exactly 4 m, and the distance from floor to ceiling is 2.5 m.
2. We measure the repeat (repetition of the pattern on the wallpaper sheet), let’s say it is 54 cm, given the length of the roll is 10 m, and the width is 53 cm.
3. Now you need to calculate a number that is a multiple of the rapport (in our case 54 cm) and as close as possible to the height of the wall (in our case 2.5 m). To obtain this number, the possible value of the rapport number is determined at which all parameters will be met.
4. As a result, if the step is four (4*54), the full cut will be 2.16 meters. This value is not enough for a given ceiling height of 2.5 m. Therefore, we increase the step to 5 (5 * 54), and this number is already suitable, it will be 2.7 m.
5. Having calculated from the length of the roll (10-2.7 * 3) we find that 3 whole strips can be used for further use.

In this work, the first tape plays a very important role. After all, if you glue it crookedly, in the future the joints of the wallpaper will go at an angle and the whole picture will deteriorate. To prevent this, a plumb line is often used, which can serve as an accurate guide for evenly gluing both the first strip and the next ones. This measure, although optional, is recommended, because neglecting this little detail increases the risk of beveled blades.

Offset docking

With this method of gluing the joints of wallpaper, the pattern shifts along the second strip. It turns out that with the indicated shift of ½, the repeat length will be 2 times less than the original value. Consequently, a drawing 54 cm long will be reduced to 27 cm.

The pattern is adjusted so that every second strip is 2 times smaller than the first (in our case, 27 cm). But the multiplicity of the pattern in height is now determined to be 54 cm for the first, third and remaining odd stripes, and 27 cm for the second, fourth and subsequent even stripes.

Free docking

This gluing method will help you properly glue the wallpaper end-to-end and reduce material loss to a minimum. But it should only be used for canvases with small and symmetrical designs. Of course, it is worth calculating the length and height of the walls, but adjusting the design is no longer required, which saves resources and effort.

Counter joining method

This method is often used to simplify work. After all, as a result, the seam will not increase and the canvases will fit tightly to each other. To do this, the wallpaper is laid overlapping, and after adjusting the pattern, it is cut at the border in a straight line.

What glue to use for repairs ↑

Not repeating previous mistakes is one of the tasks that must be solved when gluing up peeling wallpaper. A responsible approach to the choice of composition eliminates the need to repeat the procedure and allows you to eliminate damage at no extra cost. How to glue wallpaper that has come off?

Special wallpaper compositions ↑

The range of adhesives intended for finishing materials is quite wide. The compositions are presented in all price segments. On the packaging, the manufacturer indicates what type of finishing materials the mixture is intended for.

Most often they are sold dry and prepared independently immediately before gluing.

Please note that some products are intended for non-woven wallpaper; they cannot be used for paper wallpaper, and vice versa

For peeling wallpaper, you can use the remaining glue after the main repair, if the expiration date has not expired. It is economically irrational to buy a whole pack for a small fragment or several plots. When restoring a large area, when you have to re-glue almost the entire strip, the cost of a new pack is completely justified.

PVA - pros and cons ↑

Familiar from childhood, inexpensive and not requiring special training, PVA is often used when deciding what to use to glue peeling wallpaper. Glue is applied to the paper over the entire area, the strip is pressed tightly against the wall and rolled several times. It would seem that the problem is solved. However, there is a high risk of new ones:

• PVA has high adhesion and reliably glues surfaces, but is practically insoluble in water. The next time you renovate, you will have to put in a lot of effort to remove the remaining paper and completely clean the wall.
• In areas of impregnation, yellow spots with sharp contours may appear, which are especially noticeable against a light background.
• PVA is suitable for treating small areas, up to 5 cm. For more serious repairs, other compositions are recommended.

Glue for gluing wallpaper ↑

The best option for small areas, a good way to glue loose joints, top or bottom edges. Sold ready-made at any hardware store. The tube volume is small - from 50 to 100 ml. This eliminates the worry about excess.

The spout is elongated and narrowed, which facilitates application in hard-to-reach areas and allows for high-quality work on joints and corners. For a better connection, use a roller to roll the glued strip to the wall.

It is recommended to choose glue from trusted brands and pay attention to the instructions and advice from the manufacturer. Most products are universal and suitable for all types of wallpaper - paper, vinyl, non-woven, fabric

At the final stage, the glued areas are heated with a regular hairdryer.

Why paste is a thing of the past ↑

Universal household glue at one time gained so much popularity that many still cannot refuse to use the viscous sticky substance. The main advantage of the paste is its low cost and quick preparation at home. This completes the list of advantages.

If you need to glue wallpaper, paste is not helpful. It is able to cope with clean paper that is not soaked in adhesive mixture and does not harden after drying. And there is a high probability that an unpleasant surprise will await you the next morning - stripes lying on the floor. To achieve high-quality results, we use proven products from recognized manufacturers.

Loose seams between fabrics

One of the most common wallpaper problems is loose or poorly joined seams. Such a defect can be observed after gluing paper wallpaper, which can stretch slightly under the influence of moisture. After drying, such stretched canvases shrink, leaving a gap between the joints.

Such gaps are very noticeable on bright and dark wallpaper, which are strikingly different from the gray base plaster or finishing white. On light-colored wallpaper, thin gaps between the seams are not so noticeable.

An example of a bad joint between canvases

Builders with experience, having found out what wallpaper they will have to glue to the wall, can play it safe and paint the expected joints with paint that matches the wallpaper that is being prepared for hanging.

But let's return to the problem, in our case we need to correct an existing defect. This is done using putty and tinting: a color matching the tone of the wallpaper is selected, the putty is tinted and applied to the joints. Remains of putty before drying are removed using wiping materials.

After drying, the joints may be slightly noticeable at close range, but completely invisible from afar. This method involves completely masking bad joints on the wallpaper.

Many wallpaper defects could have been avoided at the very beginning of working with them - when gluing them to the wall. A properly prepared surface, following instructions, using modern materials, all these factors would help you hang wallpaper seriously and for a long time.

Applying the final layer of plaster to the wall

We have prepared a number of important aspects that should be adhered to when working with finishing materials such as wallpaper.

Wallpaper repair is not complete without removing old, damaged layers; this must be done. Wallpaper remover and warm water will make the task easier; in this case, there is a chance to remove the wallpaper in one piece. Otherwise, use a spatula. You should always prepare a wall for wallpapering. Old plaster may fall off under the wallpaper, so it needs to be dismantled. Wallpaper also doesn't stick well to paint, so we sand it down. Important elements for managing space in a room are switches and sockets, and they also need to be taken care of in advance. Firmly mounted in the box and plastered, they will not cause problems in the future. In our houses, the walls are in most cases uneven, corners are no exception.

Taking into account the fact that gluing wallpaper in the corners is a complex and responsible process, you need to take care of this in advance and slightly correct these places. Using a primer is absolutely necessary; select the composition taking into account the material of your wall. The surface should absorb moisture, thereby allowing the adhesive composition to hold the wallpaper on the wall

Properly primed walls will speed up the drying process of the wallpaper and easily hold it on. The room covered with wallpaper must be completely isolated from drafts, both during the process of wallpapering and after, until it dries. In addition, there is no need to allow excessive humidity and heat in the room. We select wallpaper glue according to the type and quality of wallpaper, for light wallpaper we choose the simplest one, for heavy wallpaper - more concentrated, for paper - paper, for non-woven wallpaper - non-woven. in water at room temperature, you should not boil it, and heating it above 30 degrees will not do it any good. When working with wallpaper, try to pay attention to the little things, control the entire gluing process, it is better to identify and correct defects immediately than to deal with wallpaper restoration or repair later.

A smooth and neat wallpaper fabric attracts attention. Using these tips, you can repair damaged wallpaper yourself, thereby returning it to its original beauty and grace. However, remember that most defects could have been avoided by correctly gluing the wallpaper to the wall

The renovation is complete, but not everyone can breathe a sigh of relief, as after some time the residents begin to notice that the wallpaper is peeling off. What to do if the wallpaper comes off the wall? You can simply carefully glue back the wallpaper that has come off, but the question arises: why did this happen and will the problem happen again?

Yes, if you don’t understand why the wallpaper peels off at the joints or comes off completely from the walls and ceilings, you can remain in the repair stage for a long time. Today you will learn about the most common reasons why wallpaper comes off and how to most reliably solve the problem.

Causes

Most often, the reasons for wallpaper coming off are mistakes made by the repairman.

When undertaking an interior renovation, it is important to approach the procedure as responsibly as possible. So, if the wallpaper has come apart at the seams at the joints, most likely, the following shortcomings were made during work:

• the walls were not checked for deformation;
• the old coating was not removed: previous wallpaper, whitewash or enamels;
• the wallpaper in the corners was pasted incorrectly;
• the glue was applied incorrectly;
• neglect of the rules of sticking;
• the glue was not selected for a specific type of wallpaper;
• the wallpaper had a paper base.

Carefully sealing wallpaper at the joints after repair is much more difficult than preventing it from peeling

So, it is important to tap all the walls with a hammer before applying glue to the sheets of wallpaper. If you see scratches, cracks, dents and chips, you need to apply cement mortar, and then plaster and prime the surface

It is the small fragments that have fallen away from the wall that begin the slow destruction of the aesthetic appearance after repair.

In addition, you should think several times before gluing trellises onto the old covering. Of course, when there are many layers of previous trellises, and some of them are thin paper types, the process can become very labor-intensive, and each person experiences conflicting feelings, caused primarily by laziness. But it is worth remembering that, firstly, the old coating may come off, and secondly, a fungus may be hiding behind the old wallpaper, which also causes the coating to come off the walls.

Another possible mistake that causes peeling is improper application. Here you should strictly follow the instructions, allowing the trellises to soak for the required amount of time.

By the way, the instructions will tell you which glue should be used for a particular type of wallpaper, and therefore it is extremely important to study it carefully. It is also worth remembering that wallpaper does not always peel off due to a lack of glue at the joints, because often an excess of adhesive does not allow them to dry correctly, which is why their displacement is inevitable

Very often the wallpaper peels off in the corners, and again the inexperience of the craftsman is to blame. When the seam is located in a corner on a bend that is incredibly difficult to adjust to a level, the wallpaper inevitably diverges. The solution here is simple: the corner is made of two sheets with minimal overlap.

In more expensive copies, as a rule, this problem does not exist. However, restoration may be required for completely objective reasons, for example, after flooding. At the same time, the trellises swell, acquire an unsightly shade and lag behind the walls.

In this case, it is difficult to seal deformed wallpaper, and therefore it is important to know some tricks

Choosing glue depending on the type of wallpaper

Manufacturers provide wallpaper adhesive for gluing a certain type of wallpaper (non-woven, vinyl, fiberglass, textile, paper, photo wallpaper, etc.), as well as a universal solution that is suitable for working with all types. In the latter case, you only need to comply with the following condition: the heavier the wallpaper, the thicker the glue should be mixed.

We do not recommend our clients to purchase universal glue; it is better to buy glue specifically for your type of wallpaper, narrowly targeted, or the one recommended by the wallpaper manufacturer itself (this is often the case when gluing photo wallpaper).

When buying glue, you will be faced with another choice - a dry powder mixture, or ready-made glue, diluted in the correct proportions.

There is also an option when the wallpaper is already impregnated on the inside of the canvas with an adhesive composition - self-adhesive wallpaper. It is enough to moisten them with water for a certain time, and then get to work. In some wallpapers you just need to remove the protective film while gluing. This option is attractive because you don’t need to choose glue, calculate its quantity, purchase consumables (roller, brushes) and you can safely ventilate the room immediately after finishing the painting work.

But such wallpapers have some disadvantages. They are very thin. If the wall is not sufficiently prepared for wallpapering, self-adhesive will not hide the defects and they will be very noticeable. Another disadvantage is their high cost.

Let's return to the glue, which needs to be diluted with water. This is the one that is in greatest demand. This glue is diluted in a previously prepared container with water, gradually adding a small portion of the bulk mixture. The proportions will be indicated on the packaging by the manufacturer, try to follow all instructions. Calculate the glue consumption in advance depending on the area of ​​the walls of the room, and do not forget to round up the figure as a reserve.

For beginners, there is a type of adhesive with an indicator, thanks to which the adhesive is painted in color (pink, blue) and you can clearly control where it is applied without missing a centimeter. After drying it becomes colorless.

Glue type

Each type of glue is created for a specific type of wallpaper. Many people are mistaken that this is a sales pitch from market-leading companies. In fact, each wallpaper has specific properties, and therefore requires a special substance for fastening. For example, the cheapest glue in this segment is intended for paper. It is the lightest, and therefore the price for glue is low. And if you need to work with vinyl wallpaper, then the price list for related products will be several times higher.

Of course, there is a so-called universal glue. But in general, it is used only for light-weight wallpaper, because there is no point in overpaying. In the case of decorative or relief materials, such a low-quality fastener will not work. In any case, you will have to select a specialized product line.

How to join wallpaper correctly: we do the repairs ourselves

The answer is simple: roll materials are available in a wide variety of textures and colors, which allows you to implement any design solutions. In addition, you can glue them yourself, without paying for the work of qualified specialists.

When gluing wallpaper, you should follow a number of certain rules that contribute to the long-term use of the wallpaper.

The appearance of the room will entirely depend on the quality of gluing of rolled materials. Poor-quality gluing with sloppy seams or visible overlaps will ruin even expensive wallpaper. So there is no need to rush in this matter; it is better to comply with all the requirements and work technology. Let's look at how to glue wallpaper end-to-end in more detail.

How are wall markings and wallpapering done?

Marking walls is an important procedure. Marking the walls is done using a pencil and a laser level. When the level sets the vertical, using a pencil on the wall, draw a vertical line along the entire length of the wall. Wallpapering begins from this straight line (Fig. 3).

Scheme of puttying wall joints.

Where is the best place to start marking? If the pasting is intended to be non-woven, cork or vinyl wallpaper, the marking point does not matter. Walls can be marked from the middle of the wall or from its beginning, since in the corners such wallpaper is glued in a completely different way.

How to prepare glue for use? The preparation of wallpaper glue should be carried out strictly according to the instructions provided by the manufacturer. The glue should be diluted immediately before work, in a deep plastic or enamel bucket.

How to glue wallpaper correctly? Let's look at the technology of wallpaper gluing using the example of the most popular type, i.e. vinyl wallpaper. Vinyl wallpaper consists of two layers:

• bottom (paper or non-woven);
• facial (polyvinyl chloride or vinyl), where vinyl performs protective and decorative functions.

Due to the presence of two layers in the wallpaper, they are highly durable, reliable and durable, but are quite heavy for an unprofessional craftsman. It is better to glue them together. One worker should stand on a stepladder, the other on the floor.

Due to the presence of two layers in the wallpaper, they are highly durable, reliable and durable, but are quite heavy for an unprofessional craftsman. It is better to glue them together. One worker should stand on a stepladder, the other on the floor.

How to carry out repairs correctly?

If a strip of wallpaper has come off near the ceiling or floor, then to re-glue you need:

1. Take wallpaper glue, which you dilute to a liquid state.
2. The fallen part of the canvas must be thoroughly coated with adhesive, wait about five minutes, and then carefully returned to the wall.

Important
The room being renovated should be kept closed from drafts for 2 days.

It is very important to know what you can use to glue wallpaper that has come off at the seam.:

1. It is necessary to arm yourself with a spatula, carefully bend the edges, and clean the canvas and wall of debris.
2. Then you need to apply glue to the peeled off area and press it back to the wall, using a rubber roller to make sure.
3. Wipe off excess glue with a dry, clean rag. Non-woven and vinyl wallpapers are not afraid of water, so they can be wiped with a damp cloth, while paper wallpapers can only be wiped with a dry cloth.

Wall covering type

The type of wallpaper used may vary. At the same time, it is he who determines the degree of adhesion of the material to the surface of the walls: not every material adheres well to the surface prepared for gluing. One of the common wall finishing materials popular with buyers is wallpaper:

• paper (varieties on a two-layer basis);
• vinyl (hard, smooth, porous, silk-screen printing with embossing);
• non-woven (an alternative to vinyl, more environmentally friendly);
• textile (made of fabric fibers on a paper backing);
• glass wallpaper (created on a loom from fiberglass threads);
• photo wallpaper (paper wallpaper with a pattern);
• varieties of 3D (three-dimensional, changing space);
• for painting (certain types of paper, non-woven, glass wallpaper).

In their production, various natural and artificial raw materials are used, and all varieties are roll wall coverings that require joining when gluing walls. If desired, you can join all these varieties without seams: the thicker and more textured the material, the easier it is to join, but the more demanding the rules for choosing glue.

Causes of defects

First of all, you should understand the main reasons for the formation of defects.

• 1. The divergence of the edges of the canvases. When a layer of adhesive solution is applied to the material, the absorption process begins. The variety of bases used in finishing coatings is very wide, but the cellulose component is a traditional material. The properties of the base under consideration depend on many decisions of designers, including the development of the type of coating, shape, relief and width, but the very fact of moisture absorption and expansion of its original dimensions is undeniable. No matter how much glue is applied to the joints, they will definitely move and change their original position.
• 2. The applied adhesive does not correspond to the category of wallpaper used. Materials with great thickness and weight (2-layer vinyl, textile, non-woven or fiberglass) require the application of a special adhesive with a high degree of adhesion.
• 3. Insufficient number of preparatory operations or their low quality. This factor becomes significant when a uniform layer of “finish” putty was not applied to the surface of mineral compositions, or it was not sanded well enough, or was not treated with a deep-penetrating soil solution.
• 4. Failure to comply with optimal temperature and humidity parameters during the drying process of the freshly glued coating. The room must be dried under natural conditions at 20…22º and humidity below 70%. To speed up drying, do not use heaters or create drafts.
• 5. Prolonged exposure to dampness or water vapor, for example, in the event of an emergency in a steam heating structure or a roof leak.

How to glue it correctly?

To restore wallpaper that has peeled off, it is important to follow the following algorithm:

delicately unscrew the trellises that have come away from the wall; remove the resulting dirt and putty pieces from the back of the wallpaper; Vacuum the loose wallpaper, as well as the walls or ceiling. This will neutralize the harmful effects of remaining dirt and dust; remove any signs of abrasion around the edges. This can be done using a soft, colorless eraser; if the old trellises have come away from the wall with pieces of putty and a chip has formed, the wall should be puttyed and carefully treated with a primer; Apply glue to the trellis and wall using a narrow brush. If a small piece comes off, then the glue is applied using a special tube or a regular syringe; when using paper and textile trellises, they are pressed against the wall and straightened using a rubberized roller. For vinyl wallpaper and non-woven-backed trellises, use a damp cloth

It is worth noting that it is important to move the roller and rag in the direction from the middle of the trellis to the joint; For faster drying, you can use a hot hair dryer; The glued area is smoothed out again.

Do not forget that the trellises should be delicately attracted to each other.

Nowadays, construction stores have goods for any type of repair, for any budget. If earlier we had a meager choice of paper wallpaper, now they offer many options for wall decoration: vinyl, non-woven, glass wallpaper and others. At the same time, paper ones also continue to firmly hold their positions. For each type of wallpaper, the store will offer you its own type of paste that is ideal. Depending on the manufacturer, quality and price will be different. But during minor in-line repairs, many people use PVA glue for wallpaper. Is this correct? Or maybe you can put all the wallpaper on it? In this article you will find answers to these questions and learn all the nuances of the correct use of such a familiar glue - PVA.

Preparation for gluing

Before you learn how to glue wide wallpaper, you need to ensure a smooth surface of the walls.
First we remove the old coating. To facilitate the gluing process and for beauty, remove external boxes of sockets and switches, screws, self-tapping screws, and small furniture parts. If there are dents and irregularities, smooth them out using putty, sand and prime. Otherwise, defects may spoil the impression of the repair. The surface of the walls should become dry, hard and rough.

Tools

To hang meter-long wallpaper correctly, you need to prepare:

• level;
• putty knife;
• rubber spatula - for smoothing;
• scissors;
• knife, preferably a stationery knife;
• roller;
• brush;
• sponge;
• buckets for glue and water;
• roulette

Decoration Materials

Before you start wallpapering the room and cutting wide wallpaper, keep it there for at least 2 days. Be sure to check whether all meter rolls are from the same batch - look at the markings on the label

This is important because batch differences may differ in the shade of the pattern.

Continue to study the label. On it you will read about how to glue wide wallpaper by adjusting the pattern:

1. Counter docking.

On the label you will see arrows that are located in the opposite direction. This marking means that you need to alternate the direction of the roll webs, completely turning them over from bottom to top and vice versa.

2. Direct docking.

The coating should be correctly glued to the same length and direction.

3. Free docking.

Don’t think about the design, but glue one sheet after another without adjusting the pattern of the meter roll.

4. Docking with offset.

The most uneconomical, complex and time-consuming option, because meter-long wallpaper will have to be adjusted.

Taking into account the manufacturer's recommendations, you can begin cutting the roll. Using a tape measure, measure the height of the walls, add 5 centimeters from each edge and cut on a flat surface. After cutting, number each roll so you don't mix up the order.

Glue

Even before cutting the roll, prepare glue that should match its type. Pour water into a bucket and pour in the powder little by little, stirring in a circular motion. Before gluing, let the resulting solution sit for 15 minutes. The glue will swell and become more sticky.

What are the features of gluing vinyl wallpaper?

The question of how to glue vinyl wallpaper, what are the features of working with it, worries many novice craftsmen. The process of pasting vinyl wallpaper includes the following operations:

Figure 3. Wall marking scheme.

1. Applying glue to the wall surface. The glue is applied in an even layer using a brush or roller to a width slightly larger than the width of the wallpaper.
2. Applying the top edge of the wallpaper to the prepared surface.
3. Aligning the joint of the edges. The joints should not overlap each other.
4. Gluing a sheet of wallpaper to the wall.
5. Displaces air bubbles and excess glue from under the wallpaper. It is better to do the work using a cotton rag or a soft brush, moving from the middle of the panel to the edges and from the ceiling to the floor surface.
6. Repeat the previously described operations until the entire room is covered with wallpaper.

If glue appears at the joint of the wallpaper, it should be removed immediately with a cotton rag, but under no circumstances use a brush.

Scheme for wallpapering butt joints.

After the wallpaper is glued to the walls at the baseboard and at the ceiling, excess material remains. Unnecessary material is removed from the walls using a ruler and a sharp knife with replaceable blades. During operation, the cutting part of the knife should be changed, since a blunt instrument tears and crushes the material.

How to glue vinyl wallpaper near the ceiling? Wallpaper at the top of the wall near the ceiling should be glued from a stepladder. The edge of the canvas adjacent to the corner of the ceiling and wall is turned up by 5 cm so that the glue cannot get onto the plane of the ceiling. Then the strip of material is carefully pressed against the wall and smoothed with a rag, moving along the surface from top to bottom. This is how all the canvases are glued.

If the canvases are not glued to the base of the ceiling (for example, 10-20 cm below), then before gluing them you need to mark the perimeter of the room with a level and draw a boundary line on the wall with a pencil. When gluing, you need to focus clearly on the drawn line, while aligning the joints.

Features of adhesive for joints "Methylane"

Methylane glue is great for peeling wallpaper. It allows you to connect even vinyl to the wall. It is resistant to high temperatures and is effective when gluing the material to plastic window blocks. Therefore, the composition can be used in niches of central heating radiators. Metylan wallpaper joint adhesive is suitable for the following materials:

• glass wallpaper;
• vinyl;
• interlining;
• paper wallpaper;
• heavy wallpaper;
• exclusive wallpaper;
• structural materials.

How to glue wallpaper end-to-end: technology

The most important thing is that the voids between the joints were not visible. Such an adjustment is necessary, otherwise the gluing will not be aesthetically pleasing. If you paste wallpaper without observing precision in the joints, the feeling of carelessness in pasting will remain. And this, of course, is not correct.

Step-by-step technology for wallpapering butt joints:

• Cut the roll into sheets, adding another 5 cm to the strips; the excess will then be cut off;
• Spread the canvas with glue from the center to the edges, bend the strip in half and let it soak in the glue for a couple of minutes;
• Using a plumb line, draw a vertical line so that the first strip goes straight, then you will be guided by it - why there is often a bevel, precisely because of the imperfectly evenly glued first strip;
• Wallpaper is usually glued away from the window;
• Excess pieces are cut off with a knife only after the strip has dried; do not rush to remove the excess immediately;
• Smooth the wallpaper with a special spatula; if the glue comes out from under the canvas, remove it with a rag;
• Glue the next canvas flush with the previous one without spacing; if you have to adjust the wallpaper according to the pattern, the complexity of the work increases (in this case, always take more on the tube, as some pieces will fall out due to adjusting the pattern);
• The joint should be invisible; after the strip is glued, go over it with a special seam roller that will fix the joints.

Features of preparing walls and ceilings for gluing

Non-professionals need to take into account that the surface to be pasted must be prepared. For this:

1. Remove dirt and remnants of old decorative coating.
2. They putty the surface, eliminating cavities, cracks, and other irregularities.
3. Primed. It is easier to apply the primer with a soft roller.
4. Wooden walls are treated with antiseptic disinfecting compounds.

The primed surface must dry completely. Only after this can you start gluing.

Nuances depending on the surface

The table shows the types of surfaces on which you can paste wallpaper, but you need to take into account a number of features:

Glue selection

There are no problems with purchasing such glue, which is suitable for joints/seams; it is sold in any fairly large hardware store

But it is important to understand exactly how it differs from more traditional variations of adhesives

Its consistency, when compared with conventional glue, is thicker. Traditionally, it is based on a polyvinyl acetate emulsion, although there may be alternative options.

Another French manufacturer presents a special composition

Many people believe that it is possible to glue joints with ordinary PVA glue, but this is not true; it does not have a certain set of properties, which is inherent in any glue that is focused specifically on these purposes. Here are its most characteristic features:

It has not only an emulsion, but also various types of additives that add positive properties. In particular, the setting time becomes more compressed

This is very important, because the faster the joint is fixed, the better the subsequent result will be. While such glue is not dry, it can be easily removed from the surface with a damp cloth, so even if you are careless, it will be very easy to solve the problem by wiping the surface - not a trace will remain. After drying, a transparent waterproof coating appears, which will be relatively invisible on most surfaces. The packaging of this glue differs from more traditional ones.

Usually there is a dispenser for thinner and more convenient application. Sometimes the kit also comes with a specialized brush, which allows you to apply glue more evenly even in those places that are relatively difficult to reach for the dispenser.

A popular brand is Methylane; for many, it is Methylane that is primarily associated with such adhesives, but there are many other solutions on the market.
