But they were not chosen by the manufacturers of decorative plaster by chance. The fact is that it is gray and white that are the most successful basis for applying paint of any other color.

Those who wish to minimize the complexity of facade finishing work use the technique of coloring the plaster and add a coloring agent to it before applying the finishing layer. This option is bad in that with a large amount of work, mixes of pigmented plaster can have different shades. This inevitably reduces the aesthetic appeal of the facade.

Painting will give the facade a unique look

The following types of compositions are most successful for painting decorative plaster:

  • acrylic ;
  • based on latex;
  • based on PVA (water-based);
  • alkyd;
  • oil;
  • silicone.

All of these types of paints are easily applied to the relief surface and form a protective layer, which is so important for external work, minimizing the impact of the environment on the facade. Water-based paint has many advantages, but it requires a two-layer application. Moreover, re-staining is performed only after complete evaporation of water from the first layer.

That is, 2-3 hours after it dries.

Alkyd paint is famous for its protective properties, but it also has its own peculiarities of application. These compositions require dilution with turpentine, drying oil or kerosene. Alkyd paints, in addition to their high aesthetics of the coating, have an important property for facades: they provide high-quality protection against the formation of mold or mildew.

Acrylic compounds are easy to apply, UV resistant (do not fade).

These paints are more convenient to maintain than others: to keep the facade clean, it can be washed with any cleaning agent. Acrylic paints are non-toxic, environmentally friendly and fireproof. Another "plus" of these compositions in their richest colors.

Oil paints - a high-quality covering material, but it has its own drawbacks. These include a long drying time, a large consumption per 1m2 of area, a tendency to cracking.

Therefore, oil compositions are the least popular for facades. For painting decorative plaster, it is advisable to use materials that are more resistant to ultraviolet and low temperatures.

Silicone paints are the best choice for regions with high air humidity. The fact is that these compounds have excellent hydrophobicity (water repellency). At the same time, a film is formed, characterized by high-quality vapor permeability.

This is a definite plus in painting facades faced with decorative plaster.

When buying latex paint, you should pay attention to whether the intended purpose is indicated on the packaging " for facades ". This is due to the fact that the properties of latex compositions for internal and external work differ significantly. The first ones have low frost resistance. The composition of latex paints for facade work includes components that provide the coating with high strength and moisture resistance.

Calculation of the amount of paint for painting decorative plaster

Careful preparation for the painting process, including the correct calculation of the amount of required material, will save you from annoying incidents during working hours. On any can of paint, its approximate consumption per 1m2 is indicated. But in the case of decorative plaster, it is necessary to take into account the depth and complexity of its relief, since these parameters are the main criteria in assessing paint consumption.

How to determine the required amount?

  1. Calculate the total surface area: the length of all walls is multiplied by the height (the distance from the base to the cornice).
  2. Consider the need to paint the slopes of window and door openings and calculate their area in the same way.

  3. Sum the obtained values. Let's say you get the following result: 120m2.
  4. Find out the average consumption of the selected paint on 1 m2 of surface (indicated on the container of the selected material). For example, for most alkyd paints, this figure is 150 g / m2.
  5. Multiply the total surface area by the average paint consumption: 120m2 x 150 g / m2 = 18,000 g / m2.

    The resulting figure is converted into kilograms: 18000 g / m2 = 18 kg. This is an average paint consumption per 120m2 for decorative plaster with shallow relief.

  6. If the pattern of the finishing layer is complex and uneven, the resulting figure is multiplied by 0.2-0.4.

    That is, they increase paint consumption by 20% -40%.

  7. With a two-layer coating, the average indicator indicated by the manufacturer on the packaging of the material is additionally included in the calculation of the consumption (for the calculated area of ​​walls and slopes).

This gives the approximate amount of paint required to paint decorative plaster for a particular facade.

Tools and equipment

To paint the facade, it will be necessary to erect the woods. It is impossible to carry out high-quality wall decoration with a ladder.

The same equipment is required for applying decorative plaster, so when painting, there should be no problems with finding material for the construction of scaffolding and walkways. They must be in stock.

The painting tool is chosen depending on the preferred painting technique. Brushes allow you to apply the covering layer more accurately and evenly, but with a significant amount of work, it is unprofitable to use this tool, since when using it, the duration and laboriousness of staining increases significantly. However, with some decorative plastering techniques, brushes are necessary.

They start finishing without waiting for the base layer to completely dry: 2-3 hours after its application. The time interval depends on the type of paint selected.

The technique is as follows:

  • immerse the brush in the paint for 1/3 of the bristle length;
  • apply point strokes at a distance of 30-40 cm from each other;
  • rub thoroughly brush the paint on the wall without picking up a new one.

When doing the work, they do not cash in on the brush, but strive to grind the paint as evenly as possible. It is important that the second layer is distributed only over the protruding parts of the decorative plaster relief. Thus, the coating will be given a special expressiveness due to the visual effect of a greater depth of grooves and grooves.
