The putty of walls under painting is the process of smoothing the surface. Thanks to her, all small defects and roughness of plaster are filled. In addition, after it is applied, the walls look more aesthetic, and paint is much better on them.

Advantages of putty wall

• Reduced paint consumption.
• Leaves walls.
• Prevents their cracking.
• Hides various defects.
• The surface becomes smooth and neat.

Features of putty wall

1. Single application of putty is used with improved color of the walls and under the liner of inexpensive wallpaper.
2. Two- and three-time applied under the expensive wallpaper and with high-quality coloring.
3. In the latter case, the first layer is applied to a well-primed wall with a wide spatula (from 20 cm) under an acute angle to 0.2 cm thick. The second - in the transverse direction using a more liquid composition after 24 hours after the complete drying of the previous one. The spatula holds almost perpendicular to the wall.
4. After a day, everything is sandwiched and thoroughly polished with the help of an abrasive mesh or shallow beam.

Selection of wipes

Putty - a composition for smoothing irregularities of up to 0.5 cm At the same time the best solution acrylic considered to date.. It withstands without cracking layer up to 3 cm.

As for the plaster putty, then it is deformed under the influence of moisture, so do not use it in a humid place. Harmful to it, and low temperatures, as long solution dries.

It is also desirable to process the walls different compositions. If there is no alternative, it is necessary to create a primer of each layer.

Thus, implementing the choice of putty for interior decoration, must take into account the following characteristics:

• ecological solution;
• ease of polishing;
• mechanical strength;
• an increased degree of water resistance.

Recommendations on plastered walls for painting, the price of which may vary depending on the composition:

• cement-based filler is recommended in humid;
• gypsum - used to work with a mineral base, namely, the DSP, plaster and concrete walls.

Wall putty technology under painting

The tool, which is needed

• Sandpaper.
• Tray for solution.
• Drill with paddle "mixer".
• Narrow and wide construction spatulas.

Substrate preparation

Progress:

• initially clean the walls from stains, soot, trace of soot;
• not allowed to have the outgoing plaster and formwork;
• then primed surface using a roller in one layer.

Preparation of the solution

Mix fillings can be prepared independently, focusing on instruction. In the cold season it is recommended to use warm water. To increase the effect of mixing, use the "mixer". Some types of building structure, after cooking needs some time to insist. Ready consistency putty solution to be mixed easily and not stick to the instrument.

Plastered walls for painting with his hands

Because today the cost of plastered walls for painting high enough, many will prefer the personal experience. Application technique of such a solution is not very complicated, but it requires some skill.

Progress:

• composition spread in a tray;
• using a narrow spatula evenly recruit a wide putty;
• remove excess mixture;
• we apply to the surface of the walls with a smooth thin layer with vertical and horizontal movements. Spatula Keep at an angle to the wall. The less angle, the thicker layer;
• we are waiting for complete drying;
• if necessary, we process the surface with sandpaper to remove the influx and irregularities;
• breast of the walls;
• we apply the finishing layer. It should be distributed more subtly from 0.1-, 0.2 mm per pass;
• the last layer should not exceed 0.3 cm;
• a day later, we grind the surface.

Recommendations:

• for the convenience of grinding, overst the wooden bar sandpaper;
• wall stripping can be carried out both dry and wet;
• wet grinding is recommended for lacquer, semi-wax and oil putty;
• at the end of the work, attach to the surface level. The wall should turn out perfectly smooth without roughness;
• to work, create an indoor temperature of 10-15 ° C and humidity up to 60%;
• until complete drying of the mixture, exclude a sharp temperature difference and the formation of drafts;
• starting putty is recommended to produce coarse grids or sandpaper, and the finishing smaller;
• for grinding the first layer, the size of No. 60, 80 is ideal, and for the second - No. 100,120,150.

How to avoid waving walls

To avoid possible cracking of the finished painted surface, the specialists are recommended to lay a painting mesh in the process of putting the walls, which is a polymeric product with cells up to 5 mm and a width of 1 m. It should be closed into the joint all the area and fix the first layer of putty on the plaster basis. Also suitable dry putty composition - fugenfuller. After the remaining layers are applied, which are described above.
