Of course, finishing with decorative plaster has its drawbacks:
- The probability of cracks is natural, that is, the mineral finish coatings are not elastic, therefore, cracks may appear on the wall, for example, from their movements when the building shrinks. But all the damages, as already mentioned, are subject to repair.
- The high cost of materials and finishing works - an exclusive design is difficult to create by oneself - it requires professional skills, so such repairs in the kitchen compared with the use of ordinary putty, paint or paper wallpaper will cost expensive.
What kinds are there?
Types of decorative plasters differ not only in the type of the binding component, but also in the design and technique of application. Options for the finish surface is very much, here are the most famous and popular types used for finishing the kitchen.
- Imitations of a stone- Venetian or Moroccan plaster for marble, travertine and other stones.
Venetian decorative plaster is a combination of acrylic polymer and marble dust. This is the most famous and ancient kind of decoration of walls. The texture of the "Venetian" seems to shine from within and authentically imitates marble, travertine and other stones.
This effect is obtained due to the special technique of applying the plaster with a spatula with a mixture of colors. More often than not, Venetian stucco decorates large kitchens in classical style, as well as in Art Deco, Art Nouveau and minimalism.

The complexity of this kind of finish is that the surface of the base should be brought to the ideal, because even the most minor flaws will be noticeable.
The technique of applying Venetian decorative plaster with your own hands: the composition is applied with a triangular spatula in small strokes of 4-10 layers, depending on the desired depth of the pattern. After the decorative layer dries, a protective wax layer is applied to the wall.

- Sgraffito- plaster, decorated in the sgraffito technique, can look like an applique on the wall, and can simulate an aged, exfoliated surface.
Technique sgraffito: on the prepared wall is applied 2 or more layers of plaster of different colors, and then in the upper layers a pattern or pattern is cut along the stencil by a cutter.
- Plaster for silk and velvet- surface with the effect of velvet or silk. The composition contains mother of pearl particles, which reflect the light, create a deep matte with a light luster texture. But like real textiles, plaster imitation of textiles does not have wear and moisture resistance, and therefore is less suitable for the kitchen.
- Antique Coatings- bark beetle, craquelure.
The effect of antiquity can be achieved with the help of the technique of applying craquelure, when the surface is covered with small cracks.
Technique of applying decorative plaster with one's own hands: on the prepared wall (no perfect alignment is required), a special compound is applied which, when dried, becomes cracked. To emphasize the cracks they can be further colored up.
There are also types of decorative plaster with non-colorable granules, which burst during the grouting with a spatula, creating an effect of wear.
And finally, the most famous kind of plaster under the antiquity is "bark beetle" with a fine-grained or coarse-grained filler, which during the application creates grooves. The relief depends on both the size of the pellets and the motion of the trowel.
Applying decorative plaster with your own hands as "bark beetle" look in the following video:
- Imitation of concrete- the plaster under the concrete may not have a pronounced relief, but it can not be called smooth either - the "concrete" surface is rather rough, with inclusions of sand and small pebbles.
Features of the work
- Before applying decorative plaster, you need to carefully prepare the base. For smooth and thin coatings like "Venetian the surface should be brought to a perfectly smooth and smooth state, and for rough, structural and relief - to satisfactory. Keep in mind that the wall should be without any nails and nets under the finish, otherwise the plaster will eventually "pull" the rust from the metal to the surface. The wall should be dry, smooth and clean.
- After the plaster has completely dried, it is necessary to apply an acrylic primer that has anti-mold properties, improves adhesion and thermal insulation properties;
- Immediately after the primer has dried, you can start tinting, preparing and applying the plaster mixture. The applied decorative plaster is not painted - the color suitable for kitchen design is chosen immediately and the appropriate pigment is added to the solution when kneading.
- To give the coating the necessary relief, you can use a spatula made of stainless steel, roller, trowel, sponge or even hands. Work must be carried out by one person to withstand the uniformity of the texture throughout the wall. Before applying the composition to the wall, you need to practice well - to work out the movement and the order of actions.
- When the plastering is finished, the surface should be covered with a special lacquer, forming an additional protective layer.
