begins with preparatory work.The wall under the Venetian plaster should be perfectly flat (this is especially true for corners): there should be no holes from nails, dirt, dust, or remnants of previous finishing. All potholes are sealed with a leveling mixture, then sanded with sandpaper. If you find a large number of crumbling places, it is better to re-plaster the wall. Decorative plaster requires a special primer.
Scheme of application of Venetian plaster withusing a crumbler. It is best to use a composition based on acrylic (deep penetration). The primer is applied using a wide brush or roller. The next stage is started only after the wall has completely dried. Next, you need to dilute the color. For this, it is advisable to use a construction mixer. The paint is poured in a thin stream during mixing. It is important to achieve a uniform color and consistency of the decorative plaster. After this, the mixture is left for some time to settle, then mixed again. The first base layer is applied using a wide trowel with rounded edges (made of stainless steel). The thickness of the plaster should not exceed 2 mm. It is important to study the instructions on the packaging, as some manufacturers recommend diluting the Venetian plaster with water for the first base layer. There are also special compositions on sale designed for such a substrate. After the base coat has dried, it is necessary to get rid of any unevenness and any bulges that have formed using a spatula or trowel, and also sand the edges of the walls with fine-grained sandpaper. Next comes the first layer of decorative plaster. Use a spatula to pick up a little mass and distribute it along the edge of the trowel. Then apply a thin layer of Venetian plaster with random strokes. When finishing narrow places and corners, replace the trowel with a spatula. After the layer has dried, go over it with a trowel - this is done in order to smooth out the coating and get rid of any imperfections. must be carried out with strict adherence to the technology - then the result will exceed all expectations.

The nature of the application of strokes also changes, a smaller tool is used for their application. The movements should not be repeated and monotonous. After applying the second layer, it is necessary to perform pressing (mechanical compaction of the plaster). To do this, take a trowel, press its edge to the wall, then press hard and run it over the surface. After this procedure, the pattern appears and shine appears. It is important to perform pressing before the plaster dries, for this reason, experts recommend applying the second layer of Venetian plaster in parts. If desired, you can complement the pattern with mother-of-pearl, gold or silver glaze, which is applied with a thin glaze layer. The work is fixed with a special wax. Before starting work, the wax must be mixed. It is applied with a spatula in a very thin layer, while immediately removing the excess. It is important not to return to the same place several times, otherwise dark spots will appear, which will be difficult to get rid of. After the wax dries, it must be polished. To do this, use a special suede mitten, a grinding machine or a drill with a soft attachment. It is important not to stay in one place for a long time, otherwise the wax may melt, which will lead to the formation of a dark spot. Do-it-yourself Venetian plaster is ready!

In this case, try to make the strokes not very large. Next, take a building hair dryer and dry the surface until cracks appear on it. After this, let the Venetian dry thoroughly. The craquelure is rubbed with gold, copper, silver, brown or white pearl paint. For this purpose, it is very convenient to use a foam sponge.
