Painting of decorative plaster: choice of materials, tools for work, technology of work. Painting decorative plaster. Decorative plaster: features, types, subtleties of painting. Features, types and characteristics of the decorative piece

Coating the decorative plaster with paint is the final step. Accordingly, the overall impression of the finished finish depends on the quality of this work.

Why paint plaster

First of all, consider why you should give the plaster any color at all, if they are already nicely overclocked?

There are several reasons for this:

This or the interior of the room due to the possibility of using almost any color.
Protects the coating from negative external influences such as moisture, sudden changes in temperature, ultraviolet radiation, etc.
The facade, painted in light colors, protects the room from excessive heating in hot weather. Thanks to this, you can save on air conditioning.
Gives the opportunity to change appearance interior or facade with little cost, we will consider how to repaint decorative plaster below.

In addition, high-quality and competent painting carries a number of practical functions.

Painting options

It should be said right away that there are two:

White - intended for subsequent painting.
Colored - containing tinting components. For this, even at the stage of preparing the solution, a color is added to it.

Thus, in addition to painting the plaster, it is possible to apply an already painted solution to the wall. This option is especially relevant if the surface is supposed to be monochromatic. However, it is quite acceptable to impart color to a coating already tinted in the mass.

Advice!
An interesting effect can be obtained if you use a spray gun to apply decorative plaster.
In this case, the composition must be pre-painted with color.

If decorative plaster and paint are applied separately, then finishing will require much more time, money and effort, however, it will allow the use of different colors. As a rule, for these purposes, all kinds of facade or interior compositions listed below are used.

Decorative paint

Separately, it should be said about such a type of coating as paint with the effect of decorative plaster. It can be applied to an ordinary cement surface, concrete, or other smooth surfaces, while outwardly they will resemble decorative plaster.

I must say that such coatings can imitate other textures, for example, they allow you to achieve the effect of silk, velvet, pearls, leather and many other materials. Therefore, which is better, decorative plaster or paint - you decide.

Advice!
In order for decorative paints and plasters to look harmonious and decorate the room, it is necessary to think over in advance such interior details as, etc.
It is advisable to complete a 3 D project in order to visually make sure that the decision was made correctly.

Types of paints

To paint the surface, various paints are used, which, of course, have different properties and characteristics:

Silicate - these compounds are usually used for facades. They are based on liquid glass... In addition, the composition includes mineral pigments and a filler, most often also silicate.
Distinctive features of the coating are long service life, moisture resistance, UV resistance and vapor permeability.
Limestone - most often used indoors, as they are easily dirty and washed off by sediments. However, indoors, they prevent fungus growth even on damp walls. The disadvantages of the composition include a poor color scheme, which is limited to pastel tones.
Cement - these compositions are made on a mineral basis. They fully inherit the properties of lime coatings, however, they are more resistant to moisture, but at the same time do not have bactericidal properties. Their advantage is their low price.
Acrylic - today given view most popular. They are distinguished by good performance, durability and low cost. In addition, they have the ability to hide minor surface defects.
Silicone compounds - have the best performance, but at the same time they are much more expensive than all of the above paints. The disadvantages include only slightly less elasticity and wear resistance, compared to acrylic compounds.

Thus, the choice of paint depends on the conditions in which the painted surface will be and your financial capabilities.

Paint application technique

So, having dealt with the types of finishes and coloring compositions, now we will consider the technology of applying paint.

The instruction looks like this:

First of all, the surface must be treated with a special primer. This is especially important for cement-based renders, which tend to shed particles. Thus, the adhesion between materials will be improved and the base will be strengthened.
If finishing is done indoors, then all furniture and flooring must be covered beforehand to prevent contamination.
After the primer has dried, you should proceed directly to painting. For the convenience of performing this procedure, you should purchase not only a roller, but also a special tray. The composition is poured into a tray and then, using a roller, is applied to the surface to be painted.
Typically, a single pass with a long-nap roller is sufficient to color the surface.

Advice!
Do-it-yourself plaster painting can be done only after the decorative layer has dried.
This usually takes 24 to 48 hours after the completion of the plastering work.

The nuances of working with paint and plaster

Usually, decorating walls and ceilings "from scratch" causes much fewer questions and difficulties than reworking it, for example, when performing cosmetic repairs. Therefore, further we will consider the main nuances that you need to know when performing this procedure if decorative paint and plaster are used as finishing.

Plastering over paint

Often there is a need to plaster a surface previously covered with paint. Of course, ideally, it is advisable to remove the old coating, however, this is a very time-consuming job, moreover, it is not always possible to complete it. Accordingly, many home craftsmen are interested in whether it is possible to apply decorative plaster to the paint?

This finishing option is quite acceptable, but only when performing the following base preparation:

First of all, the surface should be sanded with sandpaper.
Then the walls need to be primed with fine-grained plaster, for example, FEIDAL Streichputz, diluted 15-20 percent with water.
After the ground layer has dried, you can apply a coating of the desired grain size and texture.

Surface repainting

As mentioned above, if necessary decorative coating can be repainted.

This is done as follows:

First of all, the surface must be cleaned of dirt and dust.
Then a thin layer of white acrylic paint should be applied to the old coating. The work should be done carefully so as not to "lose" the texture.
Then, tinted wax or other colored composition is applied to the prepared surface.

In the same way, the previously painted surface is coated with decorative paint.

Output

Painting decorative plaster is a modern type of finish that allows you to bring to life the most unusual and vibrant design ideas. In addition, such a solution is very practical and affordable.

In this case, it is necessary to select the correct type of paint and apply it in accordance with the technology described above. For more information on this topic, see the video in this article.

Painting decorative plaster is the final stage of finishing. Decorative plaster can be white or gray, with the exception of the one that is purchased ready-made with the addition of a colored pigment to the plaster mixture. White or gray plaster is suitable for painting.

What paints to choose and how to calculate the consumption correctly

For painting decorative plaster, both facade and interior paints are used. They can be in organic solvents, which are silicate, acrylic and silicone compounds, or water-based.

In the event that the plaster is to be painted, then before starting work, first of all, it is necessary to determine the area of the working surface. For this purpose, the perimeter of the walls should be measured and then multiplied by the height. It is also necessary to measure the window and door openings in order to then subtract their area. Now, having selected the paint, you can calculate its approximate consumption.

The surface covered with decorative plaster usually has a well-defined relief. The higher the surface relief and the smaller the elements, the higher the paint consumption will be.

It is better to take the maximum value indicated on the paint can for the calculation. By multiplying this number by the footage of the room, double the resulting value, since the painting is done in two stages. Then, add another 15-20% to the resulting displacement.

Plastering and painting of walls, choosing tools:

The following tools are required for painting:

Roller with brush tray;
Nylon cord (on a bucket of paint to prevent splashing);
A small spiked plate along the edge of the tray.

For painting plastered surfaces, you can use a wide brush, roller or special mitten.

Decorative plaster painting - technology and methods

You can start any painting work on the plaster only after the layer of plaster for painting is completely dry. This may require waiting 8 to 48 hours. Drying times depend on the composition of the plaster mix, humidity level and ambient temperature.

If there is a tendency for the plaster to peel off or shedding, it is advisable to treat the plastered wall for painting with a colorless primer to strengthen the surface.

When the primer is dry, you can start painting over decorative plaster.

Before starting work, you need to protect furniture, floors, windows and other surfaces from splashes and drops of paint. For this, it is recommended to use a special plastic wrap, which can be purchased at any hardware or hardware store. When painting the facades, such precautions are not required, but the windows and the path near the wall should still be covered. Stir the selected paint well before use. The paint is applied to the walls with a roller or brush. When painting walls with a brush, paint is applied with both horizontal and vertical strokes.

Apply the paint first with horizontal strokes, then blend them with vertical strokes. To obtain an even color, it is recommended to shake it up periodically with the same brush that is applied to the paint, so that the paint composition remains uniform in color and density during work, and no sediment will form at the bottom. The roller painting technique is also simple. First, immerse the roller in the paint and roll it over the spiked plate along the edge of the tray to remove excess paint.

The paint is applied to the wall from top to bottom, and then from bottom to top. The stripes of paint should be applied in such a way that they lay on top of one another, approximately by 4–5 cm. As the paint is used up, the pressure on the roller increases so that the paint lies in an even layer. You can paint the wall in one or two steps. In both cases, the paint should be thoroughly shaded.

You can get a perfectly evenly painted surface if you first use a brush during application, blend well, and then “roll” the surface with a roller. The most in a simple way painting decorative plaster is painting "in one pass", that is, a complete painting of the plastered surface, including all the indentations and protrusions in the same tone. You can also try using a combination of several different colors. To do this, with the help of a roller, a light - base layer of paint is first applied to the surface. After it is completely dry, the protruding areas of the relief are covered with paint of a darker shade. This technique of giving additional volume to the plastered surface is called the dry brush method.

Sometimes, instead of dark paint, metallics are used (bronze, gold, silver). They are applied with a dry brush or a special mitten.

To soften color contrasts on a surface that has a finer texture, you can additionally rub the paint with a mitten or a rubber sponge. The same technique is used to enhance the effect of deep relief or, if you want to give the decorative coating a "antique" look. It is permissible to emphasize protruding relief details by applying bronze, gold or silver paint.

Using a short-haired roller, you can achieve an interesting effect when painting the plaster surface for painting like "bark beetle". Remaining unpainted, the grooves form a contrasting "bark beetle" pattern on the wall. This difference can be enhanced, or, conversely, muffled by first adding a coloring pigment to the plaster, and then paint the walls in the same color, but with a different shade.

How to paint non-uniform decorative plaster?

Painting textured plaster suggests some peculiarities. If textured and smooth areas are combined on the plastered wall surface, painting should be started with textured ones. Smooth elements can be painted only after the embossed ones are completely dry. If this moment is not taken into account, then when paint is applied to the entire surface of the wall, without taking into account its texture, weakly fixed particles of the plaster surface can peel off, while sticking to smooth areas. After drying, when re-applying a layer of paint, it is no longer necessary to strictly follow this sequence.

Dried and painted decorative plaster can be additionally coated beeswax, in order to give a matte sheen to the surface.

Painting decorative plaster video material:

The time-consuming work of applying decorative plaster deserves to be appreciated as a design element when creating an original interior. This is possible thanks to the coating of the facade with a monolithic coating in the most varied colors and shades that are offered today on the paint market. In addition to its aesthetic role, the coating plays the role of a protective layer that protects against external influence changes in temperature, precipitation, solar radiation. It is also possible to increase the degree of protection of the plastered facade by a skillful choice of color - light colors will prevent overheating of the walls, which, firstly, will save from premature destruction, and secondly, it will save money when using the building's air conditioning system.

It is possible to give the facade an original color without painting the material after it has been applied to the facade. To do this, the so-called color scheme (concentrated powder or liquid) is added to the wet plaster mass before it is applied to the walls, gradually bringing its color to the required shade. It is worth remembering that when dry, the color becomes lighter by half a tone or even a tone.

In this case, you deprive the facade of additional protection from external precipitation, but reduce the amount of work by eliminating the procedure for covering the plastered walls.

Staining technique

It should be noted that not every plaster mass should be tinted before being applied to the wall surface. This plaster should dry on the façade. We will learn how to cover a typical decorative or other material initially white... For this, special facade or interior paints are used.

Work on the coating of the applied plaster relief on the walls should begin only after its final drying. This may take from 8 to 48 hours, depending on the composition of the plaster mixture.

Some mixtures are made on a cement basis, therefore, they are prone to shedding or partial delamination. To strengthen it, it is treated with a special colorless primer. It is also necessary to leave time for the primer to completely dry, on top of which the plaster relief can be painted.

Secrets of the art of painting

It is possible to facilitate any painting, including learning how to work with decorative plaster with minimal losses, if you know some of the secrets of painting. First of all, you need to acquire the main devices. If the coating will be carried out with a roller, then you will definitely need a tray that will allow you to economically dispense the material on the roller and facilitate its uniform application. The tray configuration makes it easy to remove the excess from the roller.

If the work is carried out indoors, then it is necessary to provide for the use of a covering protective material that covers the floor, furniture, window sills, windows, door frames, etc. With a facade coating, protection is required only for front door, windows, and it is also worth protecting the path along the wall from splashes.

Any painting is carried out with chaotic movements. This is required in order not to allow abrupt color transitions and not to create different areas of the treated surface.

Coating methods

Let's take a look at several coverage methods below.

Painting in one pass

The simplest way for decorative plastering is to coat in one pass. For this, the entire surface, including the projections and recesses, is worked through with a roller with a long nap or with an ordinary brush. We get the "base" shade.

Reception "dry brush"

A more complex effect or the so-called "embossed coloring" can be obtained if, on top of a darker layer of "base" that has dried for at least 2 hours, a material of a different shade is applied to the protrusions of the relief, as a rule, lighter by half a tone or one tone. To apply this technique, you will need a brush or roller with short bristles, on which the minimum amount of material is collected (the so-called "dry brush" technique). The technique of embossed porousness allows to give the surface a great "volume".

"Volumetric" elements of plaster relief can be tinted with decorative metallics - coatings such as bronze, silver, gold. This type of paint is applied both by the dry brush method and with the help of a mitten by the shading of the top layer. It is easier to achieve smooth color transitions with a mitten. It must be remembered that metallics do not tolerate excesses, which always indicate a lack of taste. The purpose of bronze or gold is to only slightly shade the base color.

"Blur"

In addition to the dry brush method, a wash-type coating is applied. If the first method helps to emphasize the bulges on the surface, then the second highlights the depressions. The surface looks more advantageous if, when applying with a “dry brush”, paints are used in a lighter tone compared to the background. In the case of "blur", on the contrary - darker tones.

Coating the surface using the "wash" method is very costly and time-consuming, because its essence is as follows: a layer of a darker tone is applied to the main background of the surface, which is left for a short time to dry, and then this top layer is ruthlessly erased with a damp cloth with bulges. As a result, the dark layer remains only in the depressions, thereby creating a three-dimensional pattern. For the application of the background layer for washing, a good quality material is used that is resistant to washing the surface of the walls. For the filler, on the contrary, a cheaper non-moisture-resistant paint is better suited, which will be easier to wash off the surface.

Advantages and disadvantages of different methods

The results of both methods are difficult to assess by simple comparison, because it is only a matter of personal taste or customer request. One thing is for sure - it is much more difficult and longer to wash out the coating than to apply with a dry brush.

The more textured surface and deep relief of the plaster, the greater the consumption of material.

The coating can be carried out not only in one pass, but also in several steps: two layers of background color and finishing with a “dry brush” or “wash”. At the same time, do not forget that the excesses of the material can distort the severity of the texture.

The final "chord" of any coloring can be a protective layer of varnish, which is applied over the layer of material after it has completely dried. Any water-based varnish (eg Tikkurila, Alpina) will work. Before use, it must be diluted in water in a 1: 1 ratio, which will greatly facilitate its penetration into the depressions of the material. The finished mixture is applied with a wrung out wide brush in two or even three passes with interruptions for drying (the varnish, as you know, dries very quickly). The mixture should be applied immediately to the entire surface of the wall, avoiding smudges. The consumption of the varnish mixture will be approximately 2.5 liters of varnish per 50 sq. meters of surface.

The varnish will give the decorative plaster an exquisite shine, ennoble the colors, facilitate the maintenance of the surface, and protect not only the material, but the plaster design relief itself from the influence of external destructive factors.

By coincidence or based on one's own desires, such a need may arise as painting textured plaster, which is more than realistic to do with your own hands. And we suggest that you consider the implementation of such an event using a specific example.

Painting textured plaster is absolutely not difficult, even simple, type of work that is easy to handle with your own hands. Therefore, with a desire in mind, you can safely get down to business.

Often the need to paint textured plaster arises for only three reasons. The first, when in the process of applying a decorative coating to the solution, for some reason, they forgot to add a color scheme of the corresponding color. The second reason is practical and intended to protect the underlying decorative coating. The third reason is design decisions. So in this case, the decision to paint decorative plaster was made because of its main color. In general, decorative textured plaster is very durable, strong and can withstand wet cleaning, therefore, when choosing a paint, these features should be taken into account. For the bathroom, it is better to choose a paint that can withstand wet cleaning.

Before starting work, the required amount of paint is poured into a large container and diluted with plain water to the required consistency. In our case, this is acrylic paint, to which you can add up to 10% water.

Add color to the paint and mix thoroughly with a construction mixer or by hand. You can t
