Decorative plaster is a great alternative to traditional wallpaper. Initially, it is white or gray, which allows homeowners to show their imagination and create an interior in an original style using paint.
What paint to choose
For finishing the facades, decorative plasters "bark beetle", "American" or "fur coat" are used, which are most often painted in one color. Acrylic, silicone and silicate coatings are suitable for painting them. They are resistant to moisture and, unlike oil and alkyd paints, create a vapor-permeable film on the surface.
Facade paints tolerate temperature changes well and reliably protect the plaster from atmospheric precipitation. They are sold in the form of a white composition, which can be tinted in a special machine or independently, according to personal preferences. The consumption of different types of paint for decorative plaster is slightly different. For a single-layer coating with acrylic paint, approximately 170-200 g / m², silicate paint - 150-300 g / m² are required.
When working indoors, use water-based, acrylic or latex paints. The water emulsion requires a two-layer application, after which the plaster acquires a matte surface.
Acrylic coatings are used mainly in rooms with high levels of humidity - bathrooms or kitchens. They are more wear-resistant than water-based paint, therefore they are also used for finishing textured plaster in corridors.
Technical characteristics of latex paints practically do not differ from acrylic paints. They are versatile and fit well on any base, including cement and gypsum textured plaster.
From a technical point of view, the choice of any of these paints is not fundamentally important - the range of shades allows you to implement a variety of design ideas, therefore, customers are mainly guided by the price of the coating. The only thing to look out for when painting the facade of a building is whether the paint is suitable for outdoor use.
Technologies for painting decorative plaster
There are several common ways to paint decorative plaster:
- tinting;
- in one color;
- in several shades;
- dry brush;
- wash.
Painting technology is not difficult even for beginners - just have a standard set of painting tools:
- roller - the length of the pile is selected depending on the surface texture;
- brushes of different widths;
- tray for paint.
It is convenient to use a spray gun to paint large surfaces. This greatly improves the speed and quality of work. Before starting painting, you must wait until the plaster layer is completely dry, and then treat it with a deep penetration primer, otherwise the paint may swell and crack.
Tinting
The easiest way to color plaster, used to obtain a base shade. Decorative plaster is realized in the form of a composition of white or gray colors, which is tinted by adding a coloring pigment. Its amount depends on the required color saturation. The color is added to a container with plaster and mixed vigorously until it acquires a uniform color.
The advantage of this method is that the plaster layer has the same color throughout its entire thickness and, in the event of small chips and scratches, they will be almost invisible. In addition, after drying, the plaster already has a color and there is no need for additional painting work.
Painting in one color
Another easy way is to paint the plaster in one color. The painter also calls it "in one pass." The paint is applied in an even layer using a roller or spray gun, while it is necessary to ensure that all cavities and protrusions of the plaster are painted over. Then the excess paint, in the form of smudges, is collected with a brush.
When working with a roller, staining is done in vertical stripes. Each subsequent strip is rolled with an overlap of several centimeters to the previous one. For uniform coloring of the wall with a wide brush, the coating is applied first with vertical movements, then overlapped with horizontal ones. You can also paint the wall first with a thick layer of paint with a brush, and then spread it evenly over the surface with a roller.
The one-pass painting method can be used on all types of decorative plaster.
Painting in several shades
This method allows you to add expressiveness to plaster, painted in one color. First, paint is applied in one pass, as described in the previous method. Smears on the wall and excess paint accumulated in the recesses of the plaster are carefully removed with a dry brush or roller.
To apply the second tone, use a roller with a foam rubber coat or a sponge. The roller is rolled in a tray so that a thin layer of paint remains on it. After that, they lightly pass over the protruding parts of the decorative plaster, as a result of which the depressions on the surface remain in their original color, and the protrusions acquire a different shade. Protruding parts can also be tinted on tinted plaster.
Dry brush painting
This method is similar to the previous one, only the protruding parts are painted with a brush. Initial painting is done by tinting or in one pass. Then, with a semi-dry brush, they pass along the tops of the relief. Basically, the second paint is chosen lighter than the main color. To give the surface expressiveness, gold, silver and bronze colors are used, as well as gloss.
Highlighting plaster by erosion
The method is suitable for indoor use. First, a small area of the surface is painted in one pass with diluted water-based paint. After that, in a circular motion, a damp sponge passes over the surface, eroding the paint. As a result, the paint in the recesses of the coating remains intact and contrasts against the general background of the wall. You can add an accent by additionally toning the protruding areas of the surface with another shade in one of the above ways.
There is another common method for creating a contrasting surface without using a sponge. To do this, a wall painted in one tone is allowed to dry completely for a day. Then, manually or using a power tool, sand the surface of the wall, removing a thin layer of protruding areas along with the paint. This operation can also be done with a spatula, working "for a sdir".
Creating a Venetian plaster effect
In the classic version, Venetian plaster, imitating the surface of a natural stone, contains chips of marble, granite or malachite. The cost of the coating is quite high, but this method allows you to create the effect of Venetian plaster using only gypsum mixture, paint and glazing coating:
- The wall is painted in one pass with a long-nap roller, so that all the grooves in the plaster are filled with paint.
- Metallic paint is used as the second shade. It is diluted with a universal primer or other transparent base in a 1: 1 ratio.
- Light movements of a small foam roller are passed along the protruding areas of the relief. In this case, it is necessary to ensure that no streaks remain on the surface.
- At the next stage, the plaster is covered with acrylic varnish. It is diluted by 30% with water and glitter is added, creating a shimmering effect, at the rate of 1 teaspoon per 1 liter of varnish. The resulting mixture is treated with the surface of the plaster using a foam roller. During operation, the varnish must be regularly mixed, since the glitter tends to settle to the bottom.
You can experiment and add other components to acrylic varnish, achieving a variety of effects and shades.
Additional compositions for the treatment of decorative plaster
You can make the appearance of the plaster more effective and create an additional protective layer using wax, varnish and various glazes.
The wax creates a protective, waterproof coating that gives the surface a shine and vibrant color. Suitable for any kind of plaster, looks especially impressive on a Venetian. There are both transparent and colored formulations on sale. Dust must be thoroughly removed from the substrate before application. Plastering is done in one go without stopping. The setting time of the wax is about 4 hours, during this period, the resulting flaws can still be corrected.
Varnish is a one-layer topcoat. Creates a durable water-repellent film on the surface, which strengthens the plaster, protects it from damage and, most importantly, makes the appearance of the finish more attractive. For work indoors, acrylic varnishes are used, outside - on organic solvents.
Before work, the composition is thoroughly mixed, if necessary, glitter or coloring pigment is added. The coating is made in one layer using a foam roller. Approximate consumption - 50-80 g / m².
Glaze is a translucent translucent paint finish that allows for smooth color transitions. It is used for application on a flat and embossed surface both indoors and outdoors. Works can be performed at temperatures below + 10 ° С. The coating is applied with a sponge or a special mitt with strokes.
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 market of painting materials. In addition to the aesthetic role, the coating plays the role of a protective layer that protects against external influences of temperature changes, precipitation, and 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 must be tinted before it is applied to the surface of the walls. This plaster must dry on the façade. We will learn how to cover a typical decorative or other material that is originally 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 secrets of painting work. 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 dose the material on the roller and facilitate its uniform application. The tray configuration makes it easy to remove 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 covering, protection is required only for the 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 method for decorative plastering is to coat in one pass. To do this, a roller with a long nap or a regular brush is worked through the entire surface, including the protrusions and recesses. We get the "base" shade.
Reception "dry brush"
A more complex effect or the so-called "embossed staining" 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 relief protrusions, as a rule, lighter by half a tone or one tone. To apply this technique, you will need a brush or roller with a short bristle, on which the minimum amount of material is recruited (the so-called "dry brush" technique). The technique of embossed porousness makes it possible to give the surface a great "bulk".
"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 other hand, a cheaper non-moisture-resistant paint is better suited, which will be easier to wash off the surface.
Advantages and disadvantages of different ways
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 off 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 intervals 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.

Not all types of decorative plaster are tinted before application. Therefore, there is often a need to paint the plastered surface. Creative approach to this task can achieve various interesting effects and make the surface of the plaster even more attractive.
Painted decorative plaster
Below we will consider the basic rules by which decorative plaster is painted, as well as get acquainted with some design techniques for interior decoration that allow even the most ordinary decorative plaster to be made effective and aesthetic.
Surface preparation
Before you start painting, you need to prepare the surface. If the plastered walls have been unpainted for some time, it is necessary to wipe them with a damp cloth to remove dust.
Some coatings (usually cement-based) tend to peel off. In such a case, the surface must be treated with a deep penetrating transparent primer to strengthen the finish.
In the photo - deep penetration primer
The priming process is as follows:
- the container with the primer must be thoroughly shaken or its contents must be mixed;
- then the soil must be poured into the roller tray;
- then the paint roller must be moistened in the primer liquid, squeezed out slightly and treated with it on the plastered surface;
- if there are hard-to-reach places that are difficult to get to with a roller, you should use a paint brush;
- after the soil has dried, the procedure must be repeated.
Painting
Below we will consider three options for painting decorative plaster:
Below we will take a closer look at all these color options.
Paint roller with tray
Instruments
You need to start work with the preparation of the following tools:
- long-nap paint roller;
- roller tray;
- hard paint brush;
- damp cloth;
- fine grain sandpaper.
As for the paint and varnish material, polymer water-dispersion compositions are used for these purposes. In this case, it is necessary to pay attention to the area of their application.
For outdoor use, facade paint should be used. Decorative plaster or wallpaper for painting should always be painted exclusively with interior paint, i.e. intended for interior work.
Monochrome painting
First of all, we will consider how to do one-color painting with our own hands. This work is carried out in the following sequence:
- You need to start work with the preparation of paints and varnishes. For this, the composition should be thoroughly mixed. If the coating is white, then to give it a certain color, it is necessary to perform tinting, i.e. add the required amount of color.
To determine the proportions of the latter, you first need to tint a small amount of paint, and then add color to the main part of the paint and varnish material. In order for the color to be uniform, the composition must be thoroughly stirred after tinting;
Tinting paint
- Then pour the liquid into the roller tray. It should be noted that the tray is in this case a practically necessary tool, since it allows you to dispense a set of paint with a roller and squeeze the tool against a special platform.
- After that, you need to dip the roller into the tray and treat the plastered surface with it. The composition should lie down in an even layer, without drips. At the same time, it is necessary to ensure that all the indentations of the texture are painted. If necessary, the roller should be dipped into the tray and wrung out.
- After a few hours, the procedure is repeated again.
Note! It is possible to paint decorative plaster only after it has completely dried. This can take from 8 to 48 hours, depending on the type of coverage.
This completes the work.
Dry brush painting
Dry brush effect
So, we figured out with monochromatic coloring. Now let's look at how to paint decorative plaster in two colors with a dry brush effect.
To do this, follow these steps:
- first of all, the plaster must be painted in the main color according to the scheme described above;
- after that you need to wait until the coating dries;
- then you should prepare the paint by adding a little less color to it so that it is a tone or two lighter than the background;
- then a second coat of paint is applied using a brush or short-haired roller. The painting tool should collect a minimum amount of paint, which will only paint the texture protrusions.
Advice! You can tint the ledges not only with a lighter paint than the background, but also with all kinds of metallics, for example, bronze paint, silver, etc.
Blurring the painted surface
Blur method
To implement this method, it is advisable to use different paints and varnishes:
- it is better to use expensive waterproof paint for the background;
- for the second layer, it is more expedient to apply a composition intended for dry rooms. As a rule, the price of such coatings is much lower.
The instruction for painting in this way looks like this:
- first of all, a base layer of a moisture-resistant paintwork should be applied, which should be lighter than toning;
- after the surface dries, a tint layer of paint and varnish material is applied, which must completely cover the surface, including recesses;
- after the second layer has dried, the protrusions must be wiped with a hard, damp sponge. If the second layer is also moisture resistant, you can use sandpaper soaked in water. The only thing is that the work must be done carefully so as not to erase the first layer.
As a result, the dark layer should remain only in the depressions.
Blur example
It should be noted that this method is more laborious and time consuming. However, in this way you can achieve a very interesting result.
Here, perhaps, are all the original and at the same time quite simple ways of painting the plastered surface.
Output
Although decorative plaster looks attractive in itself, painting can significantly improve its decorative qualities. Two-layer volumetric painting looks especially beautiful. As we found out, it is not difficult to achieve this effect on your own.

Painting decorative plaster, on the one hand, is a fairly simple operation, but on the other, it contains quite a few nuances. Therefore, for beginners, this procedure raises many questions, ranging from the choice of paint, and ending with the technology of its application. Next, I will try to answer them in detail, which will allow you to paint the surface finished with plaster with high quality and beautifully.
How to paint
For painting plaster, you can use the following coloring compositions:
- A paint that is applied over a textured surface.
- Dyes that are added to the building mixture before it is applied.
Choosing paint
In our case, the best option is a water-based polymer paint. It has several important benefits:
- Forms a thin layer on the surface, therefore does not affect the clarity of the pattern.
- Dries quickly, as polymerization occurs immediately after the evaporation of water.
- It does not have a strong toxic odor, because it is an aqueous dispersion.
- Possesses excellent adhesion.
In addition, water-based paint is quite durable. True, the durability depends a lot on the manufacturer. Therefore, one should not expect that a cheap composition will serve for a long time.
Please note that the area of application of water-based paint is different. Therefore, only its facade brands are suitable for outdoor use. For interior use, both facade and interior paint can be used.
Interior paint has a level of moisture resistance. This must be taken into account when choosing a covering for rooms with high humidity, such as a kitchen or bathroom.
As an example, I will give a few paints and their cost:
Choosing a dye
In order not to do additional work, i.e. painting, it is more advisable not to paint the plastered surface, but to add the dye directly to the mixture. The main thing, in this case, is to choose the right dye (color). If, for example, the plaster is cement-based, any pigment intended for concrete can be used.
If the plaster is polymer, acrylic color is suitable. In order not to select the composition, you can use a universal dye. They can paint not only decorative plaster, but also other various building mixtures, textured paint and other materials.
Below are the prices for dyes from various well-known manufacturers:
When calculating the required amount of coating, keep in mind that the consumption of paint applied to the textured surface will be 15-20 percent higher than the percentage specified by the manufacturer.
Painting technology

Painting in one color using a color scheme
If you decide to color the mixture with a color scheme, it is important to correctly calculate its amount in order to get the desired color. In some cases, two or even three dyes must be mixed to achieve a complex color.
In order not to be mistaken with the dye, first experiment with a small amount of plaster. Having achieved the desired color, remember the proportions of the mixture and the dye. In these proportions, add color to the main part of the decorative plaster you intend to work with. After that, the coating is applied according to the standard scheme.
Dry brushing in two colors
Painting in two colors means highlighting the relief. As a rule, paint of the same color is used for this, but in different tones. Depressions are often painted with a darker paintwork, and embossed surfaces are lighter.
But, this is just one of the common two-tone paint options. You can use other combinations as well. For example, a second coat of paint can be used to add shine to the walls. In this case, you will need a bronze coating or, for example, a silver coating.
In any case, an interesting result can be achieved by applying a second coat with a dry brush. The principle is based on the fact that a well wrung out brush or roller paints only the most convex surfaces of the finish.
As for the first layer, it can be applied in any of the above described ways. The main thing is to wait for it to dry well.
Blur painting in two colors
This technique is the opposite of a dry brush. Its principle is based on the fact that the second layer of paintwork completely covers the first one, and then it is removed from convex surfaces. As a result, the first layer appears.
Removing the second layer can be done in one of two ways:
- When freshly applied, wipe gently with a damp sponge or rag.
- After painting, time passes until complete drying, and then the surface is sanded.
The second method can only be used if the decorative plaster is tinted.
How to repaint decorative plaster
Any paint is not eternal, and it usually serves even less than the plaster itself. Therefore, over time, the question of updating it arises. But how to do this correctly, because it is very difficult to remove the old paintwork from the embossed surface?
The surface preparation technology depends on the water resistance of the paint. If the coating, for example, is a facade one or simply has good moisture resistance, then it does not need to be removed. It is enough to first clean the surface from dust / dirt, and then prime. The only thing is to prime it with a pigment primer, which will paint over the plaster in white.
If the coating is not moisture resistant, it must be removed. To do this, wet the painted surface and wait a while. After that, the paintwork can be washed off with a sponge or cloth, abundantly moistened with water. An even more efficient way is to use a steam generator, if, of course, one is available.
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 pretty overwhelmed?
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.
- It makes it possible to change the appearance of an interior or facade at low 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 preparation of the solution, 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 possible 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 a color scheme.
If decorative plaster and paint are applied separately, then finishing will take 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 facade decoration. Liquid glass is used as their basis. 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 - by far this type is the 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 indoors, then cover all furniture and flooring in advance 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, the decorative coating can be repainted if necessary.
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.
