Before deciding which plaster to choose, it is necessary to find out the chemical properties of each kind of mixture. To finish the walls apply dry plaster. 
Scheme of plaster walls
Classification of the composition
To align or give a surface a certain color or texture, it is recommended to use a monolithic decorative plaster. The mixture has the following advantages:
- durability;
- Universality;
- prompt use.
Main characteristics of different speciesplasters. Monolithic plaster heavier structure and dries long. Experts consider the main types of such a mixture to be a decorative composition. The first solution is a smooth leveling compound, which is used to prepare the walls for subsequent finishing. The decorative mixture is used for appropriate wall finishing. What kind of plaster to choose a decor, professionals know. The main component of the mixture is a binder. To prepare the plaster on a calcareous basis, it will be necessary to mix the corresponding milk with the reticulum sand of coarse fraction. Plaster on acrylic base has a high adhesion and elasticity. Polymer cement mixtures are designed to improve the mechanical properties of the layer deposited on the surface. Colored formulations are realized in the form of finished plastic material. To finish various openings specialists recommend using colored plaster. At facade works the last structure and various effects ("bark beetle") are applied. Back to contents</a>
Decorative compositions
Tools for plastering yourhands. To create a stone decoration it will be necessary to make the marking of each row on a previously prepared surface. To identify the location of the seams, apply the appropriate cord. Then the wall is covered with a plaster mix. If the composition is dry, then stones are cut. The depth of the seam should not exceed 1/3 of the thickness of the layer. To cut into stones, you need to fix the rule on the marks. For finishing use a solution, which includes granite or marble chips. If it is necessary to simulate the materials of rocks, then the facade is lined with terracotta plaster. Preliminary preparation of the surface. The mixture is applied to the walls. On the cover, make a furrow. The lines are applied horizontally, observing a step of 3-5 cm. To make a pattern on the concrete, you will need a hammer and chisel. Pre-wall surface moisturize. To make the wall smooth, a barking is performed. The coating can be applied to the original pattern or pattern. For this purpose it is recommended to use sgraffito. Finishing works in this case provide for applying to the walls of several layers of different colors. Each layer is leveled and compacted. Experts recommend applying to cover 5-6 such layers. Then draw a picture on the wall. To do this, use a stencil and pigment powder or crayons. The sample of the solution is made gradually. For finishing the walls apply Venetian plaster, which is based on marble flour and acrylic or lime component. On the surface the mixture is applied chaotically. To work was performed qualitatively, it is necessary to have relevant experience and knowledge in this field. Upon completion of such a finish, a 5 mm facing layer should be obtained.

Technology and selection rules
Scheme of applying plaster and primer to the wall. In the process of creating an interior, much attention should be paid to a combination of style and material. The adhesion index depends on the degree of purity of the wall and its wetting. To remove from the surface of soot apply 3% solution of hydrochloric acid. Lime-plaster mixture is applied to the previously fixed shingles. If the finishing work is done on a concrete surface, then the cement milk is pre-coated (for roughness). Plastered ordinary coating consists of the following layers:
- splatter (leveling);
- priming;
- finish coating.
If a decorative mixture is applied to the wall, thenthe last coating can be presented in the form of 8 layers. In this case, their total thickness should not be more than 20 mm. Work is done in one step - from top to bottom. Pre-expose beacons. The next layer is applied after the previous one has solidified. When carrying out finishing work, care must be taken to ensure that cracks do not appear on the wall. A similar defect is observed when the composition dries quickly (due to high temperature or sun rays). If the plaster is applied in the summer, then the coating is periodically moistened. The plaster is applied to the slopes with a spatula or trowel. The mixture is leveled by the rule. The choice of a plaster mix depends on the price, concrete conditions of operation and a method of carrying out of finishing works. </ ul>
