Technology for applying latex putty: features of the workflow

Characteristics

If we consider this material from a technical point of view, it is unique. That is why its use has become popular among both beginners and professional craftsmen.

Latex putty is used on various coatings, including:

• gypsum surfaces;
• walls covered with plaster;
• brick walls;
• concrete surfaces.

The only base to which latex putty is not applicable is metal. This needs to be remembered. The latex solution can be used as a finishing putty layer, which perfectly levels the walls. They can also be used to seal seams in plasterboard sheets. For repairing minor damage and small defects on walls, latex solution is a real salvation.

When cracks appear in a concrete wall or bricks, choosing a latex mortar will be the right solution to eliminate them. They are also convenient for aligning corners.

The composition of latex putty includes:

• latex as a binding component;
• plasticizers;
• fillers;
• purified water;
• antiseptics;
• hardening regulators;
• modifiers.

If we talk about technical characteristics, it is worth pointing out that:

• The layer thickness is quite thin - up to 3 mm.
• Consumption depends on what layer the solution is applied, but on average - from 0.5 kg to 2 kg per m2. If you apply the mixture in a layer of 1 mm, then the consumption will be minimal.
• The complete drying process takes about a day. This largely depends on the manufacturer and the room where the material is used. The ideal temperature for puttying is considered to be +20 degrees.

• The interval between application of layers is 12 hours. This time is enough for drying so that the next layer can be applied.
• Shelf life – 24 months.
• There are no toxic substances.

How to apply

Working with polymer putty does not require high qualifications or special tools. The technology for applying the solution is as follows:

1. Before use, buckets with the finished material must sit indoors. Suitable temperature for work: from +8 to +30ºC.
2. The surface to be treated is cleaned of contaminants: dust, oil stains, etc.
3. After this, a layer of deep penetration primer is applied to the wall.

   
   This increases adhesion to the base and reduces moisture absorption. If you need to putty gypsum board sheets, then the joints between them are pre-glued with serpyanka.

4. Before application, thickened latex putty can be diluted with clean water to 10% of the volume.
   

   Note: Any dried particles in the solution should be removed with a spatula. Otherwise they will leave scratches on the wall.

5. The putty is applied to the wall with a spatula and leveled.

6. Drying time depends on the thickness of the layer. Usually it is 4-6 hours. This is followed by finishing decorative finishing.

   
   The developing lamp helps control the evenness of the material application during operation.

Expert opinion

Sergei Shablovsky

Plasterer

Often latex (and any other polymer) putty is used as decorative plaster. If the material is tinted, it can be applied in a thin layer like “Venetian”, imitating polished marble.

Peculiarities

Like all putty mixtures, the composition of the latex coating includes:

• various fillers;
• special substances that impart plasticity and elasticity to the material;
• additional additives that give the material certain properties.

The main component in the manufacture of latex coating is an emulsion of dispersed polymer particles in an aqueous solution. There are several types of latex and depending on what type was used in the production of putty, the characteristics and properties of the mixture will depend.

Special components, such as antiseptics, are often added to latex putty. Antiseptic additives allow the use of this material in rooms with high levels of humidity, since the resulting coating will be resistant to the formation of fungus and mold.

Safety during work

The means are harmless, but the process itself includes actions that can harm a person. Therefore, the master must work in protective clothing; sanding is accompanied by the release of dust; a respirator and protective gloves are put on. There is good ventilation in the room.

The master must work in protective clothing; grinding is accompanied by the release of dust; a respirator and protective gloves are put on.

Kinds

There are no big differences in the latex mixtures produced. Depending on the composition and manufacturer, some properties of the material may differ.

Based on the form of release, the following types of products are distinguished:

• ready-to-use solution;
• dry mixtures from which you need to make a solution yourself.

Latex putty is available in a wide range of colors, which makes it easy to choose the right shade. In addition, latex mixtures differ from each other in terms of production volume.

According to the scope of application, the following compositions are distinguished:

• for interior decoration;
• for external construction work;
• universal mixtures;
• for dry rooms;
• for wet rooms.

Advantages and disadvantages

Like every type of putty mixture, latex-based mortar has its own advantages and disadvantages.

The advantages of this composition include the following properties and characteristics:

• The coating has minimal shrinkage.
• Some types of latex coating are resistant to temperature changes. This property allows the material to be used not only for interior, but also for exterior wall decoration.
• Resistance to precipitation.
• Wide range of different shades.
• High adhesion rates with various materials.
• Due to its viscous consistency, the solution easily penetrates and fills cracks on the surface.

• When dry, it forms a highly durable coating.
• Good elasticity.
• Excellent as a base for painting. This coating does not absorb paint solutions, which reduces paint consumption during finishing.
• Ease of construction work.
• The resulting coating does not crack or crumble.

Despite the impressive advantages of latex putty, it also has its disadvantages.

Let's consider the main disadvantages of the material:

• The prepared solution should not be exposed to low temperatures. When frozen, the material loses some properties. Therefore, even if the solution is thawed, it will no longer be suitable for use.
• The price for such a coating exceeds the cost of many types of putty. However, this material can be applied in a layer one millimeter thick, unlike acrylic or cement putty, which can significantly reduce the consumption of the mixture.

How to breed

Ready-made mixtures are easy to apply because they do not require additional effort and time to create a solution. But dry mixtures are much cheaper and are no less popular. Putty in powder form is diluted in plain water in a ratio of 1 to 1. There is no need to make a solution from the entire amount of plaster in the package. You need to pour a little dry mixture into the container, and then add water, stirring all the time. After mixing the mixture with water perfectly, finishing can begin, and the finished composition can be used within 1 hour, after which it will harden and become unusable.

Recommendations for application

Before starting repair work, it is necessary to prepare the surface to be treated as best as possible. Remove all dirt from the putty base, and then the surface needs to be primed. It must dry completely, and only then can you begin to putty the surface. Latex mixtures are not toxic, but sometimes people have an intolerance to some component of the composition. Before starting work, take safety precautions. Avoid skin contact with the putty, and therefore it is better to work with gloves. When performing interior work, the room must be inspected. Before applying the putty to the surface, you need to keep it indoors for a while. It is advisable to bring the solution into the room a couple of hours before starting work so that the temperature adapts to room temperature. After a little putty you need to pour it into a separate container. Dilute the very thick mixture with water, and cover the bucket with the finished mixture tightly with a lid so that the mixture does not dry out.

The material must be applied using a metal spatula. the layer thickness should not be more than 0.3 cm. Due to the fact that the mixture has excellent plasticity, almost anyone can cope with its application, even without experience. If you need to do several layers, wait until the previous one has completely dried before applying each further layer. This time may differ for mixtures from different manufacturers, and therefore it is necessary to look at such information on the packaging. Typically the coating dries in 2-6 hours. Exterior work requires certain weather conditions. Do not putty external walls when it is raining or when the surface is exposed to direct rays of the sun. Leveling the surface to make the coating smooth is done with a sponge grater. You will find other useful secrets in the next video.

Scope of application of latex putty

Latex putty is an indispensable material in the process of interior finishing and is used as a finishing surface for surfaces of various origins, including concrete, brick, wood, fiberboard and plasterboard. The only exceptions are metal surfaces, for which latex putty cannot be used as a finishing touch. It is used for leveling various surfaces, which are subsequently subject to painting with oil, alkyd and water-dispersion compositions, and are also subject to wallpapering. Thus, latex putty, the use of which is very diverse, can be used for the following work:

• Applying a finishing putty layer that performs the function of leveling the surface;
• Use as a material for sealing seams of plasterboard sheets;
• Filling small potholes, irregularities and defects, the depth of which does not exceed 5 mm;
• Texturing surfaces of various natures;
• Treatment of small cracks in plaster, concrete or brick;
• Finishing niches and corners.

For reference! The fairly wide range of applications of latex plaster is due to its high adhesive characteristics. The use of latex putty guarantees its high adhesion to concrete, brick, plastered, as well as wooden and plasterboard surfaces.

Review of the best companies

• Vetonit produces a putty of average quality that is easy to work with. Please note that if in the future you need to remove old wallpaper, it will only be removed with a layer of putty.

• Tex putty is also a worthy option. This manufacturer offers high-quality latex material - latex putty pro. And since mixtures with latex are usually not frost-resistant, Tex has developed a frost-resistant mixture especially for the cold season that can withstand short-term freeze/thaw cycles up to 5 times. Unfortunately, mixtures of this brand are sometimes counterfeited, so you should pay attention to the store where you are going to purchase this product.

• Lakra mixtures contain additives that protect the treated surface from fungi and mold. Also, mixtures from this company can withstand up to 3 freeze/thaw cycles. They sand well even after drying.

• It is better not to buy Knauf products for non-professionals: their putty mixture is applied only in a thin layer and errors are unacceptable when working with it. Good to use as a finishing layer.

• Caparol brand putties adhere perfectly to the surface, making it perfectly smooth and even. They have low consumption and low cost compared to competitors.

• The manufacturer's product Sheetrock allows you to obtain a perfectly smooth surface without visible flaws. Used as a putty for painting and to create a decorative relief surface. Shitrok mixtures can withstand up to 10 freeze/thaw cycles.

Don't know which putty mixture to choose for a wooden surface? Latex wood putty is a good option and is very easy to work with.

Precautionary measures

• Latex putty is not toxic, but you still should not allow it to come into prolonged contact with unprotected skin. No one is immune from individual intolerance. If an allergic reaction occurs, the affected area should be immediately rinsed thoroughly with plenty of water.
• Do not forget to regularly ventilate the room in which work is carried out. Fumes released by drying putty can cause respiratory irritation.
• Unused putty remaining after repair work is strictly prohibited from being poured into sewers or natural reservoirs.

Advantages, disadvantages

Advantages of latex putty:

• Minimal shrinkage. After repair, cracks are minimally likely to appear on the surface.
• Good adhesion. The layer becomes stronger and is not prone to crumbling. The putty works like liquid rubber, penetrates into uneven areas and adheres firmly to the base.
• Resistance to temperature fluctuations. At the same time, the putty retains its original properties even under the influence of frequent changes in temperature.
• Easy to apply. You can cope without any experience in construction.
• Apply the mixture in a thin layer of less than 1 mm. To obtain the thinnest possible layer, latex putty is suitable. The thickness of the layer does not affect the strength in any way.
• Large range. This helps prevent additional expenses on paint and varnish materials to correct the resulting color.
• Ease of interaction with the solution. The composition is sold in finished form. During repairs, you will not need to dilute the putty to the required consistency. Just open the package.
• Elasticity. Makes it easier to apply the mixture.

Advantages

• Different packaging. You can buy the amount of material that is required, or purchase the missing amount.
• Formation of a protective film. The mixture does not crack or crumble over time, even in the thinnest areas.

Disadvantages of the material:

• Requirements for storage conditions. During transportation and storage, standards must be observed. It is forbidden to store the mixture in too hot warehouses or in unheated rooms.
• When frozen or defrosted, the positive qualities are lost and the mixture will be unsuitable.
• Price.

Tips for choosing

Before buying any building material, it is always useful to find out the opinion of a specialist, to get useful advice from a master or a person who has used this or that putty solution. So, when choosing and using latex putty, you must:

• determine the type of surface on which it will be applied, since latex solution is not suitable for metal surfaces, and acrylic putty would be the ideal choice for wooden walls.
• Almost all types are used for interior work, but only a few types of mixtures are used for exterior work.
• This type of putty should only be purchased in heated stores.

Before use, the purchased solution must be placed for several hours in the room in which the finishing work will be carried out. This is done for temperature adaptation.

You need to make a small amount of solution to work. It is better to dilute the mixture little by little, but more often. This is due to the fact that the solution dries quickly. If a ready-made solution is used, it must be placed in small portions in another container so that debris does not get into the main container, which can subsequently scratch the walls.

• On walls that have been pre-treated with a primer, the putty applies better and more economically.
• If the putty solution is used for other purposes (for example, for papier-mâché), then it should be applied with a rubber spatula, and not with a standard one for walls or ceilings.
