PVA-based putty: features and characteristics

There are many types of wall and ceiling putty on the building materials market. Each has its own unique characteristics and scope.

One of the most popular types of such material is PVA-based putty. In this article, we will consider the features and characteristics of the composition in more detail.

Polyvinyl acetate mixes easily with water, and when dry forms a film with excellent adhesion properties. Therefore, the PVA-based putty fits well on most types of material and is universal when performing interior finishing work.

For leveling walls, a putty based on a polyvinyl acetate emulsion is not suitable, as the mixture forms a too thin layer. Basically, this mixture is used to treat walls before painting or wallpapering. PVA-based putty can be used as a finishing layer. The surface treated with such a composition will differ in whiteness and an even structure.

Dry putty has a long shelf life provided there is no high humidity in the room. The prepared mixture will be usable within twelve hours.

Polyvinyl acetate-based putty is used for interior walls and ceilings. This material can be used not only for wallpaper and paint, but also as a cladding. The finishing material is convenient for its versatility: there is no need to buy different compositions for each type of surface.

PVA putty is suitable for almost any material:

• brick;
• wood;
• cellular concrete;
• expanded polystyrene;
• drywall;
• plaster;
• paints and varnishes;
• MDF;
• Chipboard.

In addition to standard applications, the putty mixture can be used for the manufacture of decorative elements.

Like all other types of putties, the PVA-based mixture has its own distinctive features and advantages. Let's highlight the main advantages of such material:

• high levels of adhesion to various surfaces;
• smooth and even surface;
• has no unpleasant odors;
• low probability of cracking on the surface, since this type of putty has good elasticity;
• easy to apply;
• environmental friendliness;
• resistance to the formation and spread of mold and mildew;
• perfect white color.

The main disadvantage of such a material is, first of all, in the limited scope of application. PVA putty can not be used:

• For outdoor use.
• For leveling walls. To avoid delamination and cracking, such material should not be applied in thick layers.
• For decorative finishing.
• For ceramic and tile.
• In rooms with high humidity.

In the modern market of finishing materials, you can find compositions that are adapted for use in certain conditions. Many manufacturers are ready to offer a putty that can be used in wet rooms.

There are advantages and disadvantages in self-production of PVA-based putty. The benefits include:

• Saving... All the components needed to make the mixture are readily available and inexpensive. Plus, you don't have to pay extra for brand awareness.
• Mix quality... You can independently change the composition and proportions to improve the technical characteristics of the putty.

The main disadvantage of a home-made mixture is the absence of special components that are added to the main composition in industrial production to improve its properties. In order to make a PVA-based putty at home, you will need the following components:

• polyvinyl acetate emulsion;
• water;
• any dry finishing putty;
• glycerol.

PVA glue must be diluted in water in proportions one to one. Add glycerin and putty to the mixture. The solution is stirred until a creamy consistency is obtained.

For the manufacture of finishing putty for wood processing, chalk and PVA glue are used. The manufacturing method is quite simple: PVA glue is gradually poured into the chalk until a pasty mass is obtained. It is important not to forget to stir the solution thoroughly and break up the lumps..

If you need to make a basic putty or a mixture for sealing cracks in a tree, you need to add fine sawdust to the mixture of PVA and chalk.

Despite the simple composition and ease in the manufacture of finishing material based on PVA, it is recommended to purchase a finished product. In the conditions of industrial production of putty, special substances are added to the main components that improve the quality and characteristics of the finished material.

The company is one of the leaders in the Russian market for the production of paints and varnishes. The company also produces a large number of collections of putty mixtures.

Finishing material based on PVA dispersion "Cork-S" is suitable for exterior and interior decoration. The mixture can also be used to seal small cracks. The finished mixture is sold in plastic buckets of 3 and 15 kg.

The Areal + company produces environmentally friendly finishing materials from high-quality imported raw materials. Areal's PVA putty is intended for interior work and has the following characteristics:

• pure white surface color;
• has no smell;
• high rates of plasticity.

Diola is a major manufacturer of building and finishing materials. The products of this company are manufactured using imported high quality components.

Polymer-adhesive PVA-based putty "Diola" is intended for applying a finishing coat on walls and ceilings. The coating can be applied before wallpapering or painting with any type of paint and varnish material. It is worth noting that the putty based on PVA of the company "Diola" has only positive customer reviews.

It is necessary to apply a PVA-based putty on pre-treated walls. Plaster or base putty can be used as the base coat. It is better to carry out finishing work at a temperature of 20 to 30 degrees Celsius.

Surface preparation begins with a procedure for removing various types of contaminants. After cleaning, the base is leveled with cement or gypsum plaster.

If, after the procedure of plastering the walls, irregularities and defects remain on the surface, it is recommended to apply a base layer of cement-based putty. The ease and speed of applying the finishing layer will depend on how well the preparatory work will be performed.

After the base for finishing is prepared, it is necessary to thoroughly clean the base layer from dust and dirt. Dust can be removed with a conventional vacuum cleaner, and a damp cloth or sponge should be used to remove dirty stains.

The surface can be treated with a solvent to remove greasy stains.... The final step before applying the putty will be the surface treatment with a primer. It allows you to significantly increase the level of adhesion. In addition, this procedure will extend the life of the coating.

After the base for the putty is prepared, you can start applying the finishing layer.

For finishing work, you will need the following tools:

• Metal narrow and wide spatula for putty. Used to apply the mixture to walls. The instrument must be absolutely clean.
• Construction gun. It is necessary for sealing cracks in the surface with a sealant.
• Construction film and masking tape.
• The mixer is construction.

Polyvinyl acetate quickly and deeply penetrates into the structure of almost any surface, so it will be difficult to remove dirt from the putty. In order not to stain the room during finishing work, windows, floors and doors must be covered with polyethylene film. The film can be fixed to surfaces with masking tape.

If wide and deep cracks remain on the wall, they must be repaired with assembly glue "liquid nails" or sealant. First, dirt and chips are removed from the crack. After stripping, the crack must be widened and patched with a construction gun.

The next step is to prepare the solution for application. If you purchased a dry putty, you need to prepare the mixture according to the instructions on the package.... If you bought a liquid putty, it is advisable to stir it with a construction mixer before applying it.

Putty is applied to the surface with a wide metal spatula. You can evenly distribute the mixture on a wide spatula using a narrow tool. The layers must be applied to the wall with wide strokes. The layer thickness should not be less than 0.5 millimeters... Drying time of the surface can be twenty four hours. Using a polyurethane float, you can polish the finishing filler for a smoother, more even surface.
