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.
Conclusion
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.
Decorative painting of walls is one of the most popular types of decoration. It is very diverse, individual, with its help you can create a unique beautiful room, which will not have an analogue. At the present time, this type of wall decoration, such as decorative painting, has become a strong competitor to conventional wallpaper.
Dyes for wall decoration, as a type of finishing material, are characterized by many advantages:
- The service life of painted coatings is a couple of times higher than that of wallpaper or plaster.
- There are no joints on the painted surface, resulting in a perfect continuous picture.
- Huge assortment of different colors and effects.
- Moisture-resistant properties help to make the walls unique, even in the kitchen and bathroom.
- In case of repainting, the existing paint layer does not need to be cleaned.
- The use of water-based paint for decorating guarantees an environmentally friendly surface that does not emit toxic substances and does not cause allergies, is an ideal solution for decorating a children's bedroom.
- Regardless of the basis of the surface (be it concrete, drywall, plaster), it fits equally well on the wall.
Decorative painting of walls has only one requirement for the coating - it must be even.
Painting tools
Painting the walls in the apartment, in addition to the paint itself, is carried out using the following tools:
- roller;
- spatulas (metal, plastic, notched, rubber);
- sponges;
- hard brush;
- sandpaper;
- stencil (for the effect of a picture on a painted wall).
Before you start decorating the walls, you need to decide what kind of decorative effect you want to get, so as not to buy an extra tool. Although the price of rollers and brushes is low, they can be used more than once.
Preparing the walls
If decorating the wall with paint for the first time, you need to prepare the surface for such a design solution. Preparation of walls for primary painting is carried out in stages:
- Cleaning the coating from the old finish.
- Surface priming.
- Inspection for flaws, which are repaired if necessary.
- Uneven surfaces are putty and sanded.
- Reprocessing with a primer.
After all the work done, the wall is ready for decorative painting.
In order for the paint to lay on the walls evenly, and there were no defects on the coating, it is necessary to wait until the putty mixture and primer on the wall dry completely.
Types of wall decoration with paint
Due to the fact that decorative paint is too expensive, an alternative is in demand by construction professionals - artistic painting of walls with ordinary cheap paint. There are several ways to create a unique space using ordinary paints. Let's consider them in more detail.
This is the name of painting the walls with decorative paint, which creates the effect of an old shabby surface. To create such a masterpiece, you must:
- Cover the surface with the selected color.
- Apply acrylic paint to create a contrasting shade.
- Apply colored glaze to the surface in combination with the shade of the painted wall, smooth it evenly over the plane with a wide brush, and when all surfaces are covered with glaze, touch the uncured paint with the same brush.
- With a round paintbrush, you need to poke randomly over the surface, thus making the walls look antique.
This method of application has only one drawback: all irregularities and bulges become more noticeable.
This decorative painting is a great idea for decorating an office, it gives the impression that the walls are covered with leather. After preparing the surface, you need to start finishing:
- We cover the walls with latex paint of our favorite color.
- Making a suede brush.
- Mix the glaze with latex paint, slightly darker than the surface tone.
- We cover a piece of the surface with the mixture, moisten the suede brush in water and wring it out, with light touches we apply it over the not dried coating, making stains, and partially removing it.
- Blot any visible lines with a piece of wet suede to give the leather a natural look.
Venetian plaster effect
One of the most beautiful and decorative ways to paint walls. To recreate the Venetian effect, you must perform the following stages of work:
- Place latex paint in a wide container. Sprinkle a little pigment for paint on one side, gently stir half with a stick so that the dark and light side comes out in the container.
- We take a lighter paint on a spatula and apply it to the coating like ordinary plaster.
- Dip a spatula in a dark color and cover a piece of the wall.
- When light and dark spots appear on the wall, we begin to drive the spatula along the wall in different directions in order to evenly smear the colors for a harmonious look.
At the final stage, the Venetian plaster is sanded with fine emery paper and rubbed with a special wax compound.
To create the "Venetian plaster" effect, only a plastic spatula should be used during work.
Wrinkled skin effect
This effect is simple to create, but it takes patience, because everything is done slowly, gradually.
- We take a piece of paper, paint a piece of the wall according to its size.
- We crumple the sheet, apply it to the surface, begin to smooth it, while creating the outlines of the crumpled coating.
The entire wall is gradually processed in small pieces.
On the video: the effect of crumpled (shabby) leather on the wall.
For decorative painting of walls, you can use not only purchased tools, but also available tools. A regular rag roller creates an interesting indoor effect that is suitable for children's rooms. In the case of using this method, surface preparation may not be ideal, because this type of finish hides all the imperfections on the wall.
Roller painting steps:
- Apply the first coat of paint, wait for it to dry.
- Dilute another shade of the base color (slightly darker than the previous one).
- We moisten a rag in the paint, twist it to make a tourniquet, wrap a roller with it.
- Paint from the very top of the wall to the bottom in different directions to get a textured pattern.
Types of paints
Wall decoration with special dyes for wall decoration is a diverse material. They have many color tones and look beautiful. Types of decorative paint differ in properties based on the composition.
The components of the composition of the paint are divided:
- acrylic;
- latex;
- water-based;
- alkyd and oil.
Acrylic paints
They are most often used for painting walls in an apartment. They are popular due to their value for money. They have the following properties:
- fireproof;
- make walls strong and durable;
- resistant to temperature changes;
- dry quickly, create a protective film on the walls;
- adhere well to the coating;
- environmentally friendly;
- have an assortment of more than a thousand.
Latex paints
- lack of a pungent odor;
- high degree of fire safety;
- the paint does not react to a sharp change in air temperature;
- dilution with plain water is possible;
- dries quickly after application;
- resistance to abrasion;
- environmental Safety.
In addition to positive qualities, there are also negative ones. The color scheme of this type of paint does not have bright colors, and under the resulting film, good conditions are created for the living of biological organisms. Prime the surface well before using the latex stain.
Water-based paints
They are in demand for painting rooms without creating an interior, their price is low, and they cope with the direct purpose of painting surfaces. The advantages of water emulsion include:
- low cost of material in the construction market;
- low consumption during application;
- harmlessness to health;
- have good moisture permeability.
Among the disadvantages of a water-based coating, experts distinguish the speed of washing off the coating, as well as the need for a certain temperature in the room during painting.
Alkyd and oil paints
Alkyd and oil based dyes are characterized by a rich finish color, a durable layer. The positive qualities of these types of finishes are:
- rich beautiful colors;
- very durable layer when dry;
- long service life.
Negative qualities are also present: it is a very pungent smell during painting, a large consumption of material, high cost, a small assortment of colors.
In order to save money, many want to paint the walls with their own hands, without the help of professionals. But how do you apply decorative paint yourself? There are some recommendations of experts regarding the application of decorative paints to walls:
- Before painting the surface, it must be primed to avoid the appearance of mold.
- Prepare the room by covering the floor with protective film.
- Stir the paint well after opening it.
- When using a brush, apply horizontal stripes and then smudge them vertically.
- If you use a roller, you need to roll it along the tray with the material, then - from top to bottom, then cover the walls with paint, pressing the tool well (for a uniform color).
In order for the coating to turn out to be evenly colored, you must first apply a layer with a brush, and then go over the painted surface with a roller. If desired, you can apply a variety of decorative staining methods.
Do-it-yourself decorative painting of walls is a very real task. The main thing is to adhere to the instructions for using the material along with the recommendations for application.

Which paint is best for decorative plaster? What tools to work with? How to prepare the surface? What are the main stages of work?
The easiest and most logical way to paint decorative plaster, in my opinion, is to add the required color (tint) to the previously mixed plaster and already apply it to the walls of the color you need.
The second method, perhaps the most common, for painting plaster is by applying paint to an already finished surface. In this case, it is better to use water-based paints (acrylic, silicate). It is important to follow some basic rules for the durability of the painted surface:
- painting should be carried out only after the decorative plaster has completely dried (after about 48 hours);
- before painting, you can cover the work surface with acrylic primer;
You should also pay due attention to the materials with which you are going to apply paint to decorative plaster:
- you can use a wide brush, roller or, for example, a special mitten;
- using a brush or roller, as a rule, uniform painting of the working surface is carried out;
- also, with the help of a rubber sponge or mitten, you can create an interesting pattern, the texture of the plastered surface, by rubbing the paint;
- you can also make three-dimensional decorative plaster by combining the sequence of surface painting:
A lot depends on the type and texture of decorative plaster, because the main thing is to know what effect you want to achieve when painting. As for paints, they can be water-based or organic-based, it all depends on your desire and wallet.
The choice of tools depends on the relief of decorative plaster and on the desired result, mainly painting is done with a roller or brush, but in special cases sponges, grout cloths, spatulas with a comb or other working tools are used.
Preparation of the surface of decorative plaster requires processing with a colorless primer for better adhesion of paint to the plaster, after the primer has dried, you can start painting. If you want to get a well-painted surface, apply paint with a brush, filling in all the reliefs, and then roll it with a roller. If you want to have a non-uniformly painted surface - start painting with a roller, and then dry with a sponge.
The types of staining of decorative plaster depend on its texture and design, which you want to have on the walls of your house or your apartment, and the paint can be any, from water-based to enamel on an alkyd basis. It is good to lay on decorative plaster alkyd enamel for interior work Alpina Mattlatex, after painting the walls can be washed, therefore it is suitable for finishing bathrooms, kitchens and balconies.
It is very easy to paint! To do this, use water-based paint, paint rollers with a long nap, brushes and, as an industrial version, a spray gun.
Preparation consists in removing debris and dust from the surface, you can brush it off with a broom or a rag, you can blow it off with a vacuum cleaner or spray bottle.
When painting, hard-to-reach places are first painted over, these are corners, elements of decorative patterns, small places, as well as places around doors, windows and other objects.
If you paint in a monochromatic shade, then, in principle, the movements do not matter, but if you have purchased an expensive iridescent or tinted / structured paint, then you must paint with movements in one direction!
Do not rush to cover it up right away, it is better to walk with a thin layer, let it dry, look at the gaps and flows in color, paint again with a thin layer, let it dry up and finish the work with one more control layer for problematic places.
The question is not concretized, there are a lot of decorative plasters, and, accordingly, they are painted in different ways. For example, pebble plaster such as "lamb" and "bark beetle" can be painted with a roller or spray. 
For painting, facade acrylic and silicone paints are suitable, if inside the room interior paints and varnishes are suitable. If you paint the "bark beetle" in two layers with different paints, you can get an interesting texture.
Here is a plaster like "Manna"
By painting the plaster with a brush, you can also get a great pattern. 
Painting of decorative plaster is the final stage of laborious and lengthy work on the application of this finishing material. Its natural color is unattractive for decorating not only facades, but also interior spaces. Most often it is gray or white. The first will give the building a dull look, the second - rather easily soiled.
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 labor intensity of facade finishing work, use the technique of coloring the plaster and add a dye 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 decorative plaster is beneficial in that it allows you to implement any design idea. There are several painting techniques that significantly increase the chance of obtaining a unique and most effective facade finish. But to complete this task, you need to correctly choose not only the color, but also the type of paint.
The following types of compositions are most successful for painting decorative plaster:
- acrylic;
- latex based;
- based on PVA (water-based);
- alkyd;
- oil;
- silicone.
All of these types of paints are easily applied to a 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 application characteristics. 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 are a high-quality covering material, but they have their 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 light 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). In this case, a film is formed, characterized by high-quality vapor permeability. This is an undoubted "plus" in painting facades faced with decorative plaster.
When buying latex paint, you need to pay attention to whether the packaging indicates the designation "for facades". This is due to the fact that the properties of latex compositions for internal and external work differ significantly. The former 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 staining process, including the correct calculation of the amount of required material, will save you from annoying incidents during work. 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?
- Calculate the total surface area: the length of all walls is multiplied by the height (the distance from the base to the eaves).
- The need to paint the slopes of window and door openings is taken into account and their area is calculated in the same way.
- Summarize the obtained values. Let's say you got the following result: 120m2.
- Find out the average consumption of the selected paint per 1 m2 of surface (indicated on the container of the selected material). For example, for most alkyd paints this figure is 150 g / m2.
- The total surface area is multiplied 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.
- If the pattern of the finishing layer is complex and uneven, the resulting indicator is multiplied by 0.2-0.4. That is, they increase paint consumption by 20% -40%.
- 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 the walls and slopes).
This gives the approximate amount of paint required to paint the decorative plaster for a particular facade.
Tools and equipment
To paint the facade, you will need to build scaffolding. It is impossible to carry out high-quality wall decoration with the help of 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.
Scaffolding prices
Scaffolding
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 complexity of staining increases significantly. But with some decorative plastering techniques, brushes are necessary.
To apply a single color layer, rollers on a short handle are most often used. These tools allow you to handle large volumes of surfaces without much difficulty. Roller application does not require any professional skills. The only thing worth considering: if this tool is mishandled, smudges and stripes of different shades may form. In order to avoid these troubles, you need to act in strict accordance with the step-by-step instructions below for painting decorative plaster.
Another popular tool in this type of work is the spray gun. It is excellent for applying a uniform layer to the façade evenly. When working with this tool, it is important to observe one condition: keep it at the same angle in relation to the wall throughout the entire paint application phase.

Depending on the chosen facade design, you may need:
"One-pass" decorative plaster painting technology
The "one-pass" painting technique is the simplest, but it is only suitable for a relatively smooth topcoat with few protrusions and indentations. To apply paint, you need a roller with a fur coat with a pile of medium or maximum length.
When choosing this tool, take into account the depth of the grooves on the decorative plaster.
One-pass painting is used when applying the first layer in a two-layer painting. Therefore, this method can be considered basic. It is the basis for the use of various decorative techniques that provide the plaster with an even more effective appearance.
One-pass staining technique
Step 1. Preparation of tools and equipment.
At this stage, they check the strength of the scaffolding and stairs used as supports when performing work. Determine which container will be used for paint: a bucket (when working with a brush) or a tray (when working with a roller).
If it is not possible to use a tray, the paint is poured into any suitable stable container. A piece of plywood, hardboard, thick thick cardboard is suitable for rolling a roller. They are determined with the length of the handle for the roller and choose the option that is most convenient in a particular case.
Step 2. Paint set.
Dip the roller into a container of paint so that it is immersed in 1/2 of the coat. Take out the roller and roll it 2-3 times on a special platform on a tray or a piece of plywood.
Step 3. Paint application.
Bring the roller to the wall and hold it with uniform pressure from bottom to top or top to bottom. Thus, paint is applied in even stripes. Moreover, each next one should go to the previous one by at least 3-5 cm. In places where the relief deepens, they tend to make a stronger pressure on the surface of the wall.
You can also use this technique: apply a thick layer of paint with a brush and shade it with a roller, evenly distributing it over the part of the wall.
The most spectacular are the surfaces to which the two-layer painting technique is applied. To give the facade a special expressiveness, two paint colors are used. Moreover, the first base layer can be either darker or lighter. Its application is carried out in accordance with the "one-pass" technique.
The second layer is facing. Various decorative techniques and techniques are used to apply it. All of them are available for a novice master with no experience in painting decorative plaster.
Reception "dry brush"
With the help of this method, a spectacular surface "like gold", "metallic", "like bronze" is obtained. This technique is also suitable for applying paint in two colors or shades of the same color. To get the job done, you need a paintbrush with short, firm bristles and a paint tray.
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 1/3 of the bristle length;
- dot strokes are applied at a distance of 30-40 cm from each other;
- thoroughly rub the paint on the wall with a brush, without recruiting a new one.
When doing the work, they do not cash in on the brush, but they 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.
Instead of a brush, you can use a foam sponge or a fluffy surface mitt. After the paint has completely dried, the wall can be coated with beeswax, which will give the facade an even more stylish look.

Decorative technique "Blur"
“Blurring” is a more complex method of applying a finishing layer when painting decorative plaster. It will also require significantly more paint consumption than when using the "dry brush" technique. To complete the work, you will need a damp cloth or foam sponge.
Step 1. On a completely dried first coat of paint (often of a lighter color), a second coat is applied using the "one-pass" painting technique.
Step 2. After staining, wait a while until the paint begins to harden. Without waiting for its complete "setting", they start washing. To do this, lightly erase the paint from the top layer of the relief so that the base, lighter (or darker) layer becomes visible. Use a damp sponge (rag).
This method of decorating a plastered surface is used if the base layer is applied with moisture-resistant paint. Or, even more conveniently, it consists of a pigmented plaster mix.
An effective and inexpensive way to paint decorative plaster with water-based paint
This method, invented by craftsmen, will provide a spectacular wall surface with little financial and labor costs. To complete the work you will need:
- plastic or rubber spatula;
- water-based paint;
- brush.
Decorative plaster staining technology
Step 1. The wall is tinted in the chosen color using the "one-pass" technique. Wait until it dries completely.
Step 2. Apply a small amount of lighter or darker water-based paint with a brush.
Step 3. Immediately after application, start rubbing the paint over the wall surface using a plastic or rubber spatula. The directions of movement can be different: diagonally, vertically or horizontally. It is important that the paint layer is of a minimum thickness and is evenly distributed over the section of the wall.
Step 4. By applying dotted strokes next to the treated surface, continue to rub the paint. Thus, the entire area of the decorative plaster is covered.
Step 5. The work is continued until a bright expression of the relief of decorative plaster is achieved. The grooves should remain light and the ridges darker. This effect will persist even after the water-based paint has dried. The expressiveness of the relief can be achieved in the case of applying the composition of the same color as the base layer.
Various stencils can be used to decorate facades. This technique allows you to obtain buildings of unique beauty, which will invariably attract admiring glances.
Video - How to paint a plastered facade correctly
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 with 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.
