The emulsion of the polyvinyl acetate is well diluted in water, it creates a smooth film with a good clutch when drying. At the same time, it deeply penetrates the surface of the walls and is compatible with the majority of building materials. Therefore, putty on the basis of PVA is universal in use for internal work. The low cost of components and availability of their free sale allows you to make a mixture yourself with minimal cost.

PVA glue as a basis for universal finishing material
My Vadik and I have a few single aunts, which helps as far as possible. At the cottages, Repair did themselves and as they thought. It's time to put in order from urban apartments. Therefore, it was not necessary to bored. All work was carried out under the lessons of savings and the correct use of materials.
Washing wall
It was useless to resist, and we were widely used:
- Polyvinyl acetate emulsion - PVA glue;
- a piece of chalk;
- talc;
- Carboxymethylcellulose - dry base of mesh glue CMC.
All components cost cheaply, dissolved in water and freely sold in the store or kept on the antleesoles with "old" times. Do not be surprised by the complex chemical names of widespread substances. One of the aunt chemist and the rest taught.
PVA fastener is universal and falls almost to any material. Otherwise, the surface is grounded diluted in half with water glue, and adhesion is provided with both a wall and paint applied from above.
When creating finishing putty, PVA serves as the basis. Mel is used as a filler. Talc is not reflected, but it has a small fraction and contributes to the formation of a smoother surface. CMC is used as a plasticizer, gives soft to putty and after hardening it is grouped with less effort.

In the industrial manufacture of putty, protective substances are added, repelting rodents and insects, repelled dust and binding soluble components of the mixture, making it resistant to moisture. Additional plasticizers on a latex basis prevent cracks.

PVA-based spacure has a weak smell characteristic of glue. After drying, he disappears. All components are natural and harmless. Many manufacturing recipes. Each manufacturer has developed its compositions. They include natural substances, fibers and polymers. For dry mixtures, the amount of water is indicated on the package and the proportion should be kept.
Older people in practice of small repairs tried various options. Some add liquid soap, other solution of economic or washing powder and even air conditioning for linen, gypsum, lime in the amount of up to 10%. All this is done with the aim of increasing the plasticity, and prevent the cannon of homemade putty after drying.
The chalk and glue PVA remain unchanged in the composition of putty. The surface is distinguished by smoothness and white. Wallpaper and paint do not require the clarification of the base. Apply a decorative ornament and a picture can be without aligning the tonality of the background. As a primer, diluted PVA glue is used.
Advantages of a simple composition
Wall decoration putty
Universal on the use of PVA-based putty has many advantages:
- low cost;
- naturalness;
- does not comprise harmful substances;
- The weak smell disappears with drying;
- does not require special skills of work;
- smooth surface and white color;
- high adhesion;
- Availability of self-making.
The popularity of putty, created on the basis of PVA, in its versatility. For different surfaces, it is not necessary to buy separate compounds. It is stored for a long time in a dry form without air access, more precisely moisture. Applicable for finishing most building materials:
- wood;
- brick;
- aerated concrete;
- Styrofoam;
- plasterboard;
- Chipboard and MDF;
- stucco on a different basis;
- Paint, including oil.

When prepared, putty due to the dispersed state of the PVA, forms a homogeneous mass suitable for 12 hours when stored in a closed container. It should not be mixed further. The finished putty does not settle and is not separated.
Disadvantages of putty on PVA and errors when applying
Wall decoration
With all its uniqueness, putty on the basis of PVA cannot be applied:
- outside;
- in wet premises;
- for alignment;
- as decorative textured;
- under the tile.
Powder and chalk powder is applied with a layer of 0.5 mm and their number up to four. Otherwise, a network of cracks is formed. Used only as the finish. It is applied to a flat surface, smoothing irregularities equal to the size of the fraction of the main components of plaster - sand and cement.
Many complain of difficulties with the removal of protrusions and grinding putty on PVA. I cleaner the next slack-applied grater after setting to complete drying. The surface turns out smooth, almost mirror. Time and effort to work goes a bit. Sake and primed each layer.
Tip! Buy a putty or dry mix only in corporate stores. Choose a well-known manufacturer. On putty from simple components, especially many fakes.
To improve the adhesion and the service life of putty, the surface in front of the trim should be cleaned well from dirt and dust. The primer from dilute water PVA is applied in 2 layers.
Independent manufacture of mixture for smooth painting alignment
Plow-based powder
Our aunt brought us chalk and CMC. PVA glue with Vadik bought themselves. Instead of Talca, we were given a baby sinking. Then we explained that not only the proportional number of components is affected on the quality of the putty, but also the quality of the chalk grinding, the purity of the talc and others. Therefore, we forced our aunts to calculate us the ratio of these components to obtain a mixture with specified characteristics:
- density;
- viscosity;
- plastic.

Put the walls with your own hands
In finished putty, in addition to the main substances, various plasticizers, antiseptics and a number of other components are introduced. All additives improve the quality of the material. The cost in the store is slightly above homemade putty.
For those who want to make the composition independently tell some moments. First mix dry components, only then leut the liquid. CMCs dreamed with water to the state of sour cream. It, like Talc, should not be more than 10% of the total weight without water. As a result, you should have a mass like a consistency on home sour cream.
