Is it possible to varnish wallpaper, and what kind of paint and varnish material is suitable for this purpose? Previously, I myself asked this question to specialists, but now, having personal experience and knowledge, I will answer it. I will also tell you how this procedure is performed correctly.

Varnish increases the moisture resistance of wallpaper and makes it more attractive

What you need to know about wallpaper varnishing

Is it possible to varnish trellises?

I’ll say right away that not all wallpaper can be varnished. The following types can be subjected to similar finishing:

• Paper;
• Liquid;
• Non-woven for painting. Keep in mind that they need to be painted first, otherwise the canvases will become transparent.

Sometimes people doubt whether liquid wallpaper can be varnished, and whether this will affect its attractiveness? There is a special varnish on sale for these purposes, which only improves the quality of the finish.

Liquid wallpaper coated with varnish is easy to clean - this allows you to decorate kitchen walls with it

There is no point in varnishing vinyl trellises, since they themselves are washable. However, if the canvases are painted, you can give them a beautiful glossy film.

Why varnish

Wallpaper, of course, is a finishing material in itself, so varnishing it is completely optional. However, such a solution has its pros and cons, which we will consider below.

Advantages:

• Moisture resistance. Ordinary paper photo wallpapers can be varnished, after which they become washable. Of course, this applies not only to paper trellises, but also to any other canvases exposed to moisture;

Thanks to the protective treatment, paper photo wallpaper can be used even in the bathroom

• Glossy film. After varnishing, the walls become glossy, as a result of which they look more interesting and unusual. True, if you wish, you can use a matte finish;
• Strength. After finishing, the trellises become more wear-resistant and impact-resistant.

Varnished trellises become more durable due to increased strength and wear resistance

You can use varnish for photo wallpapers only if they are really paper and do not have any protective treatment. Recently, there are washable photo wallpapers that cannot be varnished.

Flaws:

• Transparency . After varnishing, the wall can be visible through the wallpaper;
• Surface imperfections will be obvious. Glossy film highlights all the imperfections of the wall;
• Removing wallpaper will become more difficult. The process of removing varnished trellises is very labor-intensive;
• Possibility of peeling off edges. When hardening, the paint and varnish material shrinks, as a result of which the canvases can move away from the walls in areas where the edges are poorly glued.

Many beginners are interested in the forums - how and with what to remove varnished wallpaper? To do this, you can use a sander with a brush attachment. Another option is to pick up the canvas with a spatula and pour water into the space between it and the wall.

Therefore, you yourself must decide whether to varnish the wallpaper or not.

Acrylic varnish is environmentally friendly - it has virtually no odor

Pros and cons of washable wallpaper

Each of the above types of wallpaper has advantages and disadvantages. Non-woven - with a dense structure, which allows you to hide uneven walls. The top of this finishing material is embossed; wallpaper is also made that can be coated with water-based emulsion. Minus - dust accumulates in the relief surface.

Acrylic ones are made on a non-woven base. The surface of this wallpaper is foamed acrylic. This type is environmentally friendly and durable. Despite the embossed wallpaper pattern, they can be washed. Minus - when washing acrylic wallpaper, you cannot use a brush and detergent.

Vinyl wallpapers are divided into flat, dense and foam. Flat – made using the silk-screen printing method. Dense – quite difficult to glue on your own, since the wallpaper is quite heavy.

The most suitable ones for the kitchen are vinyl ones with a vinyl foam coating. The surface of this finishing material is difficult to damage, and the deposited grease deposits on the wallpaper can be washed off using a detergent for cleaning. The disadvantage is the complexity of installation and the possibility of condensation forming on the dense vinyl sheet.

Fiberglass - called matting. They are perfect for painting, do not deform, and are resistant to scratches and temperature changes. The matting can be washed using detergents.

How not to make a mistake and choose the right washable wallpaper for the kitchen so that it lasts for a long time? Of course, each buyer makes a choice at his own discretion, but if there are doubts about the correctness of the choice, you can consult with the seller.

Which varnish to choose

The best solution in our case is a water-based polymer varnish. Why is he the best? The fact is that this paint and varnish material has a number of positive qualities:

• Environmental friendliness . The material is odorless and harmless to health;
• Good adhesion. The coating fits well on any type of wallpaper;
• Drying speed. Under normal conditions it dries in 2-3 hours.
• Durability . The material can last for many years while maintaining its attractiveness;
• Easy to apply . The composition is easily applied with your own hands with a roller, while forming a smooth surface.

When choosing acrylic varnish, you need to consider the following points:

• Moisture resistance . This indicator may be different for different brands of the varnish in question - some of them can be washed, while others can only withstand gentle wet cleaning. In the kitchen, use a washable varnish, but in dry rooms, for example, in the living room, just a moisture-resistant coating is enough;
• Surface type . As I said above, the paint material in question can be glossy, matte or satin.

Wallpaper laid on the floor under varnish looks interesting. If they have a pattern that imitates wood, then the floor resembles parquet or laminate. Such a finish can last more than ten to fifteen years, the only thing is that nitro varnish should be used as a finishing material, and it needs to be updated every few years.

How to apply varnish

In order to correctly apply varnish to the wallpaper, so that you do not later regret your decision, but, on the contrary, enjoy the “fruits of your labor” with pleasure, you need to meet several conditions.
Wallpaper preparation:

1. Wallpaper that was pasted some time ago should not be opened with varnish; such “worn-out” wallpaper will “show” all worn and damaged places when varnished
2. Before pasting the wall, carefully level it and after filling and priming, paint the entire surface with white water-based emulsion, this way you will even out the tone of the wall, and this is very important when opening the wallpaper with varnish, because varnishing “highlights” differences in tone and stains very “high-quality”
3. glue the wallpaper with very strong glue or add PVA to the solution
4. carefully glue all joints
5. Prime paper and non-woven wallpaper with PVA solution before varnishing
6. start applying varnish only after the primer layer has completely dried
7. Apply in two layers, waiting for the previous one to dry completely (about a day)
8. To apply varnish, use a roller, a brush will leave unsightly and noticeable streaks

Advantages of varnished wallpaper:

• moisture-repellent properties are acquired or increased - varnished wallpaper can be washed
• durability - the design will remain “safe and sound” much longer, the colors will not fade and the surface will not wear out
• the wallpaper will acquire brighter colors and a glossy surface (or matte, it all depends on the type of varnish)

Disadvantages and difficulties:

• the wallpaper may be too deeply saturated with varnish and become translucent; to avoid such a “surprise”, be sure to prime the wallpaper before varnishing with a layer of diluted PVA; the film formed in this case will prevent the varnish from “seeping” excessively into the canvas
• when drying, a layer of varnish can “spoil” the wallpaper - by shrinking, undermining the joints or air pockets
• Apply glossy varnishes only to a perfectly leveled and evenly painted surface - it highlights all the slightest irregularities and defects; if in doubt, give preference to matte or semi-matte varnish
• removing varnished wallpaper will still be difficult, nothing has changed since our childhood, although modern wallpaper removers and a special needle roller will come to the rescue

Application technology

Finally, let's look at how to varnish wallpaper. This operation includes three main steps:

The main stages of wallpaper varnishing

The instructions for doing the work look like this:

This completes the work.

Wallpaper varnish: advantages, disadvantages, application

The main advantage of varnish for paper wallpaper is the surface's resistance to mechanical damage and moisture. After successfully applying varnish to paper wallpaper, you can wash it and remove dust with a damp sponge. Non-woven wallpaper can also be coated with the same composition. There is no point in treating vinyl with varnish; it can be washed and cleaned anyway, if the layer of material is thick enough. Special varnishes are produced for liquid wallpaper and cork wallpaper. Bamboo wallpaper can be coated with a composition for wooden products.

Varnish for paper wallpapers adds extra shine and makes them brighter. If you do not want to increase the intensity of the color, then before varnishing it is worth covering the wallpaper with a solution of PVA glue.

Another advantage of varnish for paper wallpaper is protection against mold and other parasites. This is especially important for rooms with increased humidity.

Technology for working with washable wallpaper

Treatment of areas where wallpaper adjoins electrical outlets.

Despite the fact that washable wallpaper has a fairly dense structure, which allows it to cope well with unevenness and defects in the base, it is preferable to treat the wall with putty and then clean it. After the canvases are cut, they should be kept for several minutes, only then can you begin gluing them.

It is better to glue thick wallpaper end-to-end. Initially, the surface should be primed using liquid glue, which can be replaced with a primer with deep penetration action, after which the surface should be treated with a special composition that prevents the appearance of mold, despite the fact that glue with appropriate additives of a similar effect will be used.

After the primer has dried, you should determine the vertical according to which the first wallpaper will be glued. It is better to use the plumb line method as a guide, as it is the most convenient.

The surface must be dry before wallpapering. Before the pasting process, you have to get rid of the old wallpaper, the cracks should be filled with putty, and the surface should be leveled.

In order to determine whether the walls are dry enough for wallpapering, you should glue a small piece of polyethylene to the surface. If moisture does not appear on it overnight, then the surface is ready to begin the gluing process.

Applying glue to wallpaper.

Surface strength is also very important. This can be determined by sticking a piece of tape to the surface, after which it should be pulled back sharply. If old paint or plaster remains on its surface, then the surface must be rid of old coatings. Also make sure that there are no drafts in the room while gluing the walls.

When gluing the canvas, you must ensure that the adhesive does not get on the base of the front side of the wallpaper. After the wallpaper glue has swelled, it should be left for 10 minutes. Then it must be applied to the wall; additional glue can be applied to the wallpaper. After the wallpaper has dried, you can open the windows and doors to ventilate the room.

For some craftsmen, gluing wallpaper in hard-to-reach places becomes a particularly difficult task, for example, baseboards and the space under the ceiling, as well as in corners and near heating pipes, with no exception the area around sockets and switches.

Near the baseboard, the canvas should be fastened end-to-end between it and the wall surface. If the lower part remains, it should be cut and glued with a strip on top, which will cover the upper area of ​​​​the plinth. In order to get a more aesthetic effect, the plinth should be dismantled before you begin pasting the room, and after completion of the work it can be installed in its original place.

Features of gluing washable wallpaper

Wallpapering the ceiling.

When gluing wallpaper in the corners, you should leave allowances equal to a slightly larger width than the depth of the niche. Afterwards, it is necessary to make cuts in the lower and upper parts of the allowances so that it becomes possible to bend the wallpaper around the corner.

You should go around the radiator with wallpaper in a special way: you don’t need to go more than 20 cm behind the radiator. The areas of the wall hidden behind the radiators don’t need to be covered at all; it is permissible to paint the wall behind the pipes in the color of the wallpaper. In those places where sockets and switches are installed, the wallpaper does not need to be cut, it must be attached to the holes. After the glue has dried, you will have to cut out the holes, giving them the shape of sockets and switches.

Washable wallpaper made on the basis of hard vinyl, although it has more weight even when dry compared to other types of wallpaper, is easier to glue, since it is unusual for them to swell from the applied adhesive composition. The density of such a material is increased, which is why it will be ensured that the wall surface is completely eliminated from showing through the canvas, which makes it possible to glue such wallpaper directly onto a concrete surface, which does not need to be pre-painted.

After the fabric is attached, you should press it to expel any bubbles. It is noteworthy that washable wallpaper is so elastic that it is permissible to peel it off from the surface several times if it is not possible to perfectly align the joints the first time. Only after they are aligned can they be carefully ironed with a roller. There should be no overlapping of the canvases; this will allow the formation of invisible seams. The adhesive mixture must have a strengthened formula so that thick wallpaper is held on the wall.

Such coatings can be glued to any surface, including gypsum fiber, concrete, plaster, aerated concrete, as well as prefabricated panels, but this is not a complete list. Other types of wallpaper that cannot be subjected to wet cleaning need to be replaced much faster. After all, sometimes a small stain can ruin the entire interior. The service life of such coatings can be 15 years, while the surface of the wallpaper will not lose its qualities. But in case of repair they will be quite easy to remove.

By covering a room with washable wallpaper, you will not only get an elegant interior, but also the ability to wash the surfaces of the walls, which is especially important in a dusty and polluted city.

How to remove varnished wallpaper?

There are several ways to remove old varnished wallpaper:

• Using sandpaper. But since the amount of work will be large, it is recommended to use a tool. As an assistant, use a grinder with a brush attachment. This attachment consists of numerous pieces of wire and is capable of quickly removing a layer of wallpaper on the wall. However, not everyone uses this method, since after treatment the wall must be puttied.
• Using special compounds. To remove wallpaper, you can use the softening compound Quelyd Dissoucol. After applying it to the surface, go over it with a needle roller. What surfaces can acrylic varnish be applied to? This way, the active substances will penetrate inside the wallpaper and reduce the adhesion of the material.
