Decorating the walls with decorative plaster is becoming increasingly popular. Apply such material and paint it is not so easy, especially since there are several varieties. Therefore it is worth considering in more detail the subtleties of the painting process of decorative plaster.

Plain plaster on a cement or plaster base is intended only for partial alignment of the walls. After its application, the surface is leveled to the end with the help of finishing putty and then painted, covered with wallpaper or other material for finishing.

Despite this, it is often necessary to paint it, for example, to create a single color scheme in the interior.

The advantages of using decorative plaster in a special aesthetics, originality of the interior. Its different types, possessing unique patterns, are used to decorate and decorate walls in shopping centers and office buildings, various institutions and even in entrances.

Decorative plaster is made from mineral or polymer components. Mineral can be based on cement or gypsum, for the latter, slaked lime is used as a binder.

Polymer are vinyl, acrylic and silicone. The composition of any of the types can be crushed solid components of various substances: crushed stone, pebbles, marble, granite and others. It is they who, when applied, form intricate patterns, such a property, for example, has the widely popular "Bark Beetle".

All types of decorative plaster are sold as dry mixes.which are diluted with water in a certain proportion and then applied to the walls.Different technologies of application, you can use a spatula, brush, rubber comb or even the palm of the hands.

Decorative plaster, depending on the characteristics of the pattern is of two types:

• textured, which after drawing gives a volume pattern on the wall;
• Venetian or texture plaster, which has a finished surface smooth surface with imitation of artificial stone.

There are several types of volume pattern of textured plaster:

• "Bark Beetle" It has small longitudinal grooves resulting from solid stones in the composition. It looks like an insect-eaten tree, which is why it got its name.
• "Lamb" the texture is filled with fine grains, the surface is fine-grained, rough to the touch.
• "Fur coat" it turns out with a rough surface and small pile.

• "Marcianide" has a complex three-dimensional pattern with spots of various sizes.
• Volumetric texture "American" granular with splashes of smooth spots of various shapes and sizes.

Mineral-based decorative plasters are well suited for decorating walls in an apartment; they are strong and durable. But for street work it is better not to apply them, as they are afraid of moisture, temperature changes, sunlight.

PVC-based vinyl plaster, protected from dampness, ultraviolet radiation, mold and mildew, can be successfully applied in the bathroom, in the kitchen, in living rooms and on the street. Its only minus in high tightness, because of which the walls in the apartment “do not breathe”.

In terms of their composition, organic paints intended for decorative plaster can be acrylic, silicate and silicone. The first ones are made of acrylic polymer resins, have a drying time of 5 to 30 hours, the surface becomes matte after use.

Silicate dyes based on silicon organic resins and metal pigments form on the surface a viscous, durable film resistant to moisture and temperature extremes.Silicone paints, water dispersion, safe at work, have resistant saturated shades.

Paint on decorative plaster can be made and mineral based. These varieties are designed to finish concrete or brick surfaces..

Despite the affordable price and a large variety of colors, mineral water-based paints have a shorter lifethan organic, less protected from adverse effects. With the help of them often perform finishing work on the plaster inside the premises and outside buildings.

Oil enamel, used for painting textured plaster, is made of quartz sand, oxides of various metals, polymeric and mineral pigments, giving the material a different color palette.

The lack of oil paints and enamels in a strong odor, which can persist after work for a long time, even with full drying.

Alkyd paints, like oil, have a sharp unpleasant odor. Most often work with them, wearing a respirator. Despite this drawback, they dry out faster than oil types, do not form stains, resistant to mechanical damage and moisture.

Experienced masters recognize that the consumption of this type is less than the rest.

When choosing a paint for decorative plaster it is necessary first of all to consider what kind of work it is - front or internal. Acrylic, silicate and silicone types of emulsions are ideal for the decoration of facades.

On sale are a huge number of shades - several hundred colors, there is a choice for any exterior. These paints are used for various textures of plaster: "Bark beetle", "Lamb", "American".

For interior work, acrylic, latex, mineral water-based emulsion paints are most often used.. You can use oil or alkyd options, but they often cause inconvenience in the work, often have to ventilate the room. But these paints give a resistant and bright film with an intense shine.

Also, when choosing a paint should take into account its consumption.

On a rough surface, the rates of one layer for various species are as follows:

• Oil enamel - 1 liter per 10 - 15 square meters. m;
• Acrylic - 1 liter for 8 - 10 square meters. m;
• Water emulsion - 1 liter per 10 - 18 square meters. m

However, this consumption may vary depending on the degree of unevenness, the rougher textures of the plaster absorb more.

You can paint decorative plaster with your own hands without any problems both inside and outside. Work begins with surface preparation. If the walls are plastered recently, you need to wait for them to dry completely, then clean from dust and debris.

Next, you need to make a primer wall. This process is very important and should not be avoided.

• Firstly, it gives a better grip, the layers will not flake off.
• Secondly, the primer solution is able to close the small pores in the decorative texture of the plaster, there will not get paint, therefore, its consumption will decrease.
• Thirdly, the primer will strengthen the structure of the plaster itself, it will be complete longer.

It is best to choose acrylic or polymer varieties of deep penetration, depending on the place - for outdoor or indoor use.

Paint is applied with a roller or brush. It is better to use a roller, as it captures a large area and distributes the composition as evenly as possible over the surface.. For him, you need to take a special bath, where periodically dunk. Painting is one movement upwards. A brush is needed in order to paint over the edges, small areas, hard-to-reach places where you cannot reach with a roller.

Textured plaster is usually painted in at least 2 - 3 layers, a smaller amount for full coverage is indispensable. Therefore, paint consumption increases. Some dilute it with water, but the lower the concentration, the more layers will have to be applied.

Painting in one color is the easiest way. It is a wide terry roller with vertical movements, the smudges are removed by him.Each previous layer closes a new one.

It is necessary to paint until all irregularities are filled with a uniform color.. This method has been used in facade work.

Painting in two colors begins with an ordinary roller to complete painting in one basic shade. After drying, you need to take a sponge or foam roller and dip it in paint with a second color so that it lies a thin layer on the surface. Then, a sponge gently passes through the protruding portions of the relief surface so that only they are colored, and the depressions retain the base color.

It is possible to paint textured walls with the effect of Venetian plaster. The base layer is performed by the usual method of coating in one color. The second shade is taken with a metallic sheen., for example, on the basis of silver or aluminum powder.

The background color is applied with a small foam roller or sponge, the protruding spots become shiny. The third stage is the application of varnish or wax, so that the surface becomes smooth, glossy film.

Any one-color surface of textured plaster can be varnished, waxed and other compounds that add shine. They will have one more useful function - protection from moisture.

So you can process relief surfaces painted with mother of pearl, bronze, ocher. The view they get is just spectacular.

Natural or synthetic wax may contain pigments that give saturated colors. Then the base paint is not required - one is enough. In liquid form, it is applied to textured walls with a soft cloth or rubber spatula. The various intensive shades which are poured on light turn out.

There are lots of interesting examples of the use of painting for various types of decorative plaster:
