Just a few years ago, plaster was used primarily as a finishing material for leveling surfaces and hiding various chips and cracks. Today the situation has changed: a special decorative plaster has appeared on the market, which is used as a final coating. Painting decorative plaster: We consider application methods.
Peculiarities
Decorative plaster, like other finishing materials, has its own distinctive features:
- This type of plaster has 2 purposes: rough leveling of walls and their finishing.
- This finishing material is resistant to fading, mechanical damage, high humidity and sudden temperature changes.
- It has two varieties. On sale you can find decorative finishing material for use indoors or outdoors.
This general features material. He also has some distinctive properties, which should be discussed in more detail.
Distinctive features
Experts consider its texture to be the main feature of decorative plaster. Thanks to it, you can create almost any design on the walls, everything is limited only by the imagination and skill of the decorator. The second feature lies in the very structure of this material. Decorative plaster contains larger particles of other materials. It is their presence that allows you to create unique bas-reliefs on walls when decorating rooms.
All components included in this finishing raw material have natural origin , which means they are completely safe for human health. During operation, the material does not release toxins into the air. For decorative plaster, you can use almost any paint: a lot of pigments are suitable for it. At the same time, the material does not absorb any odors. Decorative plaster goes well with any building materials. It can be applied to brick, stone, concrete and plaster. In fact, it is a universal finishing material.
Can it be painted?
Since this material is intended for leveling walls and finishing them, the buyer is often interested in the possibility of painting such plaster, because its natural shades are gray or white, which not everyone likes. The developers allow the process of coloring the finishing material. This work can be done using various paints, or by adding color to the mixture itself during production.
The specific type of color or coloring mixture must be chosen based on the type of finishing material itself. You also need to take into account the place where the work process will take place. If the work area is located in an apartment, it is better to choose paint that has virtually no odor or quickly erodes. For outdoor work, it is better to choose special paints with increased resistance. Each type of dye has its own characteristics and performance characteristics, which are taken into account when purchasing material.
What to choose?
The range of such finishing raw materials on the market today is quite wide. Choose the most suitable decorative plaster from the decorative plaster presented on the shelves. suitable option It can be difficult for an inexperienced buyer. Therefore, you should familiarize yourself in advance with the main types of this finish and its characteristics.
Based on the type of filler, plaster is divided into three types:
Textured
This material has a highly viscous structure and large filler particles in the composition. The use of this variety does not imply detailed preparation of the walls. It is ideal for indoor and outdoor use. The finished surface ultimately imitates leather, wood, fabric or paper. Particularly popular when carrying out external work is the so-called “bark beetle”, which is considered a type of textured plaster.
Venetian mixture
This variety has become widespread when carrying out finishing work indoors. When dried, it imitates the pattern of onyx or marble. At first glance it is difficult to distinguish it from real stones. The surface treated with Venetian plaster can be glossy or matte. By adding various colors to it, you can achieve the effect of simulating precious stones. Shades like mother-of-pearl, silver and platinum are best suited for this.
Structural
This decorative plaster consists of several layers and is made on the basis of silicate or acrylic mixtures. It has a heterogeneous structure, excellent specifications, increased resistance to moisture and mechanical shock.
Depending on the type of connecting link, decorative plaster is divided into four categories:
Acrylic
IN in this case the main component is acrylic resin. Distinctive feature This material has low vapor permeability. Such raw materials can be found on sale in ready-to-use form. The most common decorative plaster of this type is from the VGT brand.
Silicate
IN this category includes products based on liquid glass. It is characterized by high strength and durability. Can be used on any type of surface. This plaster is sold exclusively in ready-to-use form.
Mineral
This variety is made on the basis of cement. This decorative plaster is suitable for exterior use, as well as for finishing walls inside rooms with high humidity levels. It is usually sold as a dry mixture, which must be diluted with water before use.
Silicone
The main binder of this decorative plaster is silicone resin. This plaster belongs to the universal category; it can be used to decorate walls outside and inside, finishing any room in the home.
After familiarizing yourself with the main characteristics of each type, you can choose from the putty presented in the store exactly the variety that you need.
How to use?
There is nothing complicated about painting decorative plaster. You can easily do this work with your own hands. Today there are different types of coloring, for which their own ways of doing the job have been developed.
Two-color painting
For this painting method you will need the following tools:
- short foam roller;
- roller with long pile.
The process of painting the surface of a wall with an applied finish occurs in two stages. Initially, paint is applied to the entire wall using a long-nap roller. It is important that the paint layer is uniform, dense, but not thick. Only the protrusions on the wall surface are repainted using a foam roller. The layer of paint should be thin. Thanks to two-stage painting, the projections become darker, while the rest of the wall retains its original appearance. You can do it differently. To do this, add color to the plaster itself before use and apply the mixture to the entire wall, then only the protruding parts are painted with a foam roller.
Venetian plaster effect
This coloring is performed in 3 stages.
It takes a lot of time, requires diligence in work and consists of the following:
- Using a long-nap roller, paint the wall in the main base color.
- Using a small foam roller, the protruding parts are lightly painted with iridescent paint (for example, silver mixed with a universal primer in equal parts).
- Now the final coating is applied. For this acrylic lacquer on water based mixed with water in a ratio of 3: 1. A small amount of special glitter (sparkles) is added to the resulting mixture. The approximate volume is 1 tbsp. l. per liter of water. The resulting mixture is applied in an even layer of medium thickness using a new small foam roller.
The result is an imitation on the wall natural stone. This effect looks good in modern interiors apartments and country houses. This surface cladding gives the space nobility and hints at the well-being of the owners of the house.
Dry brush painting
In this case, a little color is immediately added to the plaster and only then the walls are plastered. Next, only the protruding parts are painted with paint. The peculiarity of this method lies in the fact that the paint is applied with an almost dry brush, that is, on the brush itself (the coloring agent is applied in a minimal amount).
The use of putties for cladding today is breaking all records in terms of demand. Bark beetle plaster is one of the most popular decorative coatings for outdoor and interior decoration walls
This is why painting bark beetles at home is of interest to every craftsman. Today we will look at the main principles of working with paint for plaster and find out how to paint bark beetle plaster in two colors.
What you need to know
When painting bark beetles, you should take into account not only the degree of surface preparation, but also the nuances that appear due to the uneven base. Facade material has a two-layer texture, in which the surface resembles the chaotic movement of a bark beetle along a wall. This effect was made possible by adding mineral granules into the plaster, which, when grouted, move along the base and create uneven grooves. They are the ones who cause all the problems in the process of painting the facade with your own hands.
Let's see with an example what problems will arise if the bark beetle is painted incorrectly:
- A short-nap roller will not reach all the grooves and some furrows will not be painted. This will cause great aesthetic damage to the entire cladding.
- When using rollers with long piles, a larger amount of paint is captured, which, before it has time to dry, will flow down the recesses. Have to additional tool remove smudges, and this will delay and complicate the process of finishing the plaster
The first method is to paint the solution
At this stage, the color is added to the plaster solution before applying it to the walls. In this case, you choose yourself color shade and you can even play with its saturation. This technology allows you to paint the furrows of the bark beetle, which are difficult to fill during finishing. The technique for applying the decorative solution itself does not differ from the standard one:
- Using a spatula, the mixture is smoothed over the wall and after 15-20 minutes, when hardening begins, the surface is rubbed in the desired direction
- After complete drying, painting work begins.
For the final coating, the coloring composition can be identical to the pigment that was added to the putty, or you can choose, on the contrary, dark or light shades for surface contrast. During painting, the rollers are not pressed against the walls so that the paint does not flow into the voids.
Important! Material consumption with this design method is significantly reduced.
Don't forget about the primer
We all know that primer does important functions to improve the adhesion of the surface with the finishing, so to the question of whether it is necessary to prime the bark beetle before painting, the answer is unequivocal: yes. Painting bark beetle plaster can be done using primer paint; for this, the required pigment is added to the adhesive solution. It will not be difficult to prime the design area.
The primer mixture can be applied using a sprayer or manually. The two options differ in their advantages, since the liquid solution easily gets into the furrows, as with mechanized way application, as well as during manual painting. Paint should be applied to dry walls, which will be identical to the color added to the soil.
The external facade of the house requires maintenance, so the surface must be treated immediately after drying after finishing the plastering work. It is better to buy dye with a reserve, since different batches may have different shades, which will accordingly affect appearance cladding.
How to paint decorative bark beetle plaster (video)
Classic painting method
The most common method of painting bark beetle plaster is to apply paint after completing all facing work. To do this, you should choose a color that will match and look harmonious with the roof, if painting occurs outside and with overall design, if you will be painting the interior.
Important! The bark beetle in the home interior is perfectly combined with other finishing materials. It could be wallpaper wooden panels, lining.
After you have finished plastering the walls, you can move on to choosing paints. Among modern materials These will fit:
- Acrylic solution
- Alkyd
- Oil
Important! Ready photo A sample of the surface can be seen in catalogs of painting products; in addition, most popular manufacturers of plasters create their own lines of paints, which will cost an order of magnitude cheaper.
The water-based composition is not suitable for painting bark beetles. Options for painting bark beetles with a spray gun in the video give beginners answers to all their questions. If your household has a compressor, then applying paint using a spray gun will be much more convenient. For each square meter processed, you will need less solution, and this will reduce your design costs.
You can paint it in double or even three colors, it depends on your knowledge and preparation. The two-color method makes it possible to create a three-dimensional surface, and the pearlescent shade will only enhance it. Gold is also added to the paint - this shine is used for sand and yellow bases.
Important! It is better to entrust the combination of shades to a professional or color wheel, which can be found on the Internet.
To carry out quality work, you need to know how long the bark beetle plaster dries before painting. In fact, all the information is presented by the manufacturer on the packaging, since different brands can take different amounts of time to dry. On average, the mixture will take from one to five days to dry. If you decide to plaster over the weekend, then be prepared for the fact that you will have to spend the next few days on painting.
Bark beetle applied to walls not only creates a beautiful decor, it reliably protects surfaces from negative influences atmospheric precipitation. In addition, it is allowed to putty surfaces in the kitchen, bedroom and even children's room. This indicates the safety of the material, despite which the price remains affordable for the population. The combination of qualities and advantages, the availability of samples, and easy selection of materials according to the required parameters brings bark beetle plaster to a leading position among finishing elements.
In addition, the spray gun makes it possible not only to plaster walls and apply the mixture several times faster, but also to paint the resulting bases. Putty also hides minor flaws and irregularities - this means plastering the walls with bark beetle and then painting will be even more profitable.
Photo gallery of finished works
Labor-intensive work on applying decorative plaster deserves to be appreciated as a design element when creating original interior. This opportunity is provided by coating the facade with applied monolithic coating in a wide variety of colors and shades that are offered on the paint materials market today. In addition to its aesthetic role, the coating plays the role of a protective layer that protects from external influences of temperature changes, precipitation, solar radiation. You can also increase the degree of protection of a plastered façade by skillfully choosing a color - light colors will prevent overheating of the walls, which, firstly, will protect against premature destruction, and secondly, will allow you to 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, a so-called tint (concentrated powder or liquid) is added to the wet plaster mass before applying it to the walls, gradually bringing its color to the required shade. It is worth remembering that when drying the color becomes lighter by half a tone or even a tone.
In this case you strip the façade additional protection from external precipitation, but reduce the amount of work by eliminating the procedure for covering plastered walls.
Staining technique
It should be noted that not every plaster mass subject to tinting before applying it to the surface of the walls. This plaster must dry on the facade. Let's find out how to cover a typical decorative or other material initially white. For this purpose, special facade or interior paints are used.
Work on covering the applied plaster relief on the walls should begin only after it has completely dried. This may take from 8 to 48 hours depending on the composition of the plaster mixture.
Some mixtures are made on cement based, therefore prone to shedding or partial peeling. To strengthen it, it is treated with a special colorless primer. It is also necessary to leave time for the primer to dry completely, on top of which the plaster relief can be painted.
Secrets of painting art
You can make any painting easier, including learning how to work with decorative plaster with minimal losses, if you know some secrets 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 work is carried out indoors, then the use of a covering should be provided protective material, which covers the floor, furniture, window sills, windows, door jambs, etc. When covering a façade, protection will only be required 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 to avoid sharp color transitions and not create areas of the treated surface that differ from each other.
Coating methods
Let's look at several coating methods below.
One pass painting
The simplest method for decorative plaster is one-pass coating. To do this, use a long-haired roller or a regular brush to work through the entire surface, including protrusions and recesses. We get the “base” shade.
Dry brush technique
A more complex effect or the so-called “ relief painting“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, usually lighter by half a tone or tone, is applied to the protrusions of the relief. To use this technique, you will need a brush or roller with short bristles, on which you apply minimal amount material (the so-called “dry brush” technique). The technique of relief poering allows you to give the surface greater “volume”.
“Volume” elements of the plaster relief can be tinted using decorative metallics - coatings such as bronze, silver, gold. This type of paint is applied both using the “dry brush” method and using a mitten by shading the top layer. Using a mitten makes it easier to achieve smooth color transitions. 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 just slightly shade the base color.
"Blur"
In addition to the “dry brush” method, a “wash” type coating is used. 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 more light tone compared to the background. In the case of “blurring”, on the contrary – darker tones.
Coating a surface using the “washing” method is characterized by very large physical and time costs, because its essence is as follows: a layer of a darker tone is applied to the main background of the surface, which is left on long time to dry and then this upper layer It is mercilessly wiped off the bulges with a damp cloth. As a result, the dark layer remains only in the depressions, thereby creating a three-dimensional pattern. To apply a background layer under the blur, use good quality material resistant to washing the wall surface. For the filler, on the contrary, would be better suited cheaper non-moisture resistant paint, which will be easier to wash off from the surface.
Advantages and disadvantages of various methods
The results of both methods are difficult to evaluate simple comparison, because it’s just a matter of personal taste or the customer’s request. One thing can be said - it is much more difficult and longer to wash out the coating than to apply it with a dry brush.
The more textured the surface and deeper relief of the plaster, the greater the material consumption.
Coating can be carried out not only in one pass, but also in several stages: two layers of background color and finishing with a “dry brush” or “wash”. At the same time, we should not forget that excess material can distort the expression of the texture.
The final “accord” 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 will do (for example, Tikkurila, Alpina). Before use, it must be diluted in water in a 1:1 ratio, which will greatly facilitate its penetration into the cavities of the material. Ready mix applied with a wrung-out wide brush in two or even three passes with breaks for drying (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 square meters. meters of surface.
The varnish will give the decorative plaster an exquisite shine, refine the colors, make it easier to care for the surface, and protect not only the material, but the plaster design relief itself from the influence of external destructive factors.

When renovating apartments and houses, owners try to make them look not only neat, but also beautiful and original. Many property owners today, of course, have already abandoned simple whitewashing of walls. Decorative textured plaster can also be used to decorate enclosing structures indoors and facades. In some cases, this design may also be two-color. Later in the article we will look at how to paint decorative plaster in a similar way.
How to choose paints and varnishes
There are two main ways to paint decorative plaster in two colors:
- tinting the mixture itself before application;
- painting the finished plastered surface.
The first design method is used very rarely. Decorative plaster from almost all modern manufacturers should be painted after application to the walls.
There are many ways to do this. In this case, the answer to the question of what paint to paint decorative plaster can be, for example, the following:
- water-based;
- latex;
- acrylic.
When choosing paints and varnishes for painting walls, you should definitely pay attention to what type of work they are intended for. To decorate facades, of course, choose paints whose composition allows them to be used outdoors. For indoor use, products that are cheaper and less resistant to high humidity and temperature changes are used.
Preparing the walls
Is it possible to paint decorative plaster with paint? The answer to this question is obvious. Of course yes. However, before using such a product, the surfaces themselves must, of course, be prepared in the most thorough manner.
Whatever paint and varnish material is chosen for the decoration of premises or facades, the plastered surface must be primed before using it. Otherwise, the paint will subsequently begin to peel and peel off quickly.
You should start painting decorative plaster only after the primer has completely dried. A product that increases wall adhesion is applied to the surface, usually in two layers.
Painting methods
So, we found out how to choose paint and varnish materials for decorating walls in two colors. But how to paint decorative plaster correctly when choosing this finishing method? Enough original walls look in the rooms even when using the usual method of contrasts. In this case, some parts of the rooms or facades are simply painted one color, and others another.
But very often, more than one shade can be used to decorate walls in two shades. complex technologies, allowing you to get very original design. In this case, at the first stage, paintwork materials of the same color are usually applied to the entire surface. Next, on top of this layer, the walls continue to be decorated with paint of a different shade. The following finishing methods can be used:
- star dust;
- old surface;
- abstract pattern;
- wrinkled skin.
Also, painting walls finished with decorative plaster can, of course, be done using a stencil.
star dust
In this case, a paint material of a different color is simply applied to the painted surface using a very hard brush. The main task of the painter when performing this technology is to get pronounced specks on the walls different sizes. Surfaces are finished using this technique as follows:
- the brush is dipped into the paint and wrung out thoroughly;
- bring it to the wall, bend the pile back and release it.
As a result, small drops of paint begin to fly onto the wall, which achieves the effect stardust.
How to paint decorative plaster in two colors: old surface
This technology of painting decorative plaster in two colors is also called stippling. In order to “age” the surface of the walls, in this case a wide flat brush is used.
For decoration, a special glaze is first applied to an already painted wall. Next, without waiting for this layer to dry, the master begins to touch the surface in different places flat brush. Ultimately, an original texture is formed on the walls.
Design using abstract pattern technique
Next, let's see how to paint decorative plaster using this chaotic method. For this type of wall decoration home handyman You will need to make your own special tool - a roller with a “torn” surface. To do this, you just need to take a regular roller and secure the tissue flagella folded several times along its entire length. Such elements need to be secured with fur or foam rubber using two simple knots. The strips of fabric on the working part of the roller should be held as firmly as possible.
By painting a wall with such a tool, you can get a very unusual chaotic pattern. In addition to the fact that the surfaces in this case turn out to be unusual and original, the work can be done very quickly when using a torn roller.
How to paint decorative plaster with your own hands: the effect of wrinkled leather
Using this technique, you can also design very original rooms or facades in the house. Vinyl paint is most often used for this type of decor. To perform work using this method, paper is also prepared.
In this case, the walls are painted using approximately the following technology:
- apply the first layer of paint to the walls;
- apply and crush decorative paper;
- apply a second layer of paint;
- remove excess from the folds.
Using a stencil
Many apartment and house owners would probably like to learn how to properly paint decorative plaster in two colors. The technologies described above allow you to get enough beautiful surfaces. But, of course, pronounced drawings with specific subjects can only be applied to the walls using a template.
You can develop stencils for decorating walls using paint of a different color yourself or buy ready-made ones for the appropriate theme. Today there are many different patterns and designs for decorating walls.
The technology of painting using stencils is very simple. The template is simply applied to the wall and then painted over.
How to apply the first layer correctly
Of course, a beautiful two-tone finish on plastered walls will only work if they are decorated correctly, including on initial stage. Before applying the first coat of paint on the surface, you need to wait until the primer has completely dried. In this case, the actual wall finishing itself is performed as follows:
- The corners of the room and those areas where the furniture will subsequently be located are the first to be painted;
- They try to apply the paint on the surface evenly in thickness and at the same speed in different areas.
The wall is painted before applying the second color, usually in several layers. Most paints used for decorative plaster have a fairly liquid consistency. This is necessary to ensure that no residue remains on the treated surfaces. various kinds sagging and pieces. However, the first time white plaster when using such liquid products, it may not stain.
Color combinations
Of course, before you start decorating the walls, you should decide what color to paint the decorative plaster. Paintwork materials of any shade can be used to decorate such surfaces. However, combinations of tones when decorating surfaces in this way should be chosen correctly. It is believed that the following are best suited for decorating rooms and facades in this way:
- close or related colors (beige and gray, white and black);
- gradients (paints of the same color, but different shades).
You can also select paints for finishing that are similar in temperature, saturation and sound. For example, orange goes well with green paint, and olive paint goes well with peach.
How to tint the mixture correctly
So, we found out how to paint decorative plaster correctly. Most often, this coating is finished in two colors after the mixture has been applied to the walls and it has completely dried. However, sometimes such plasters are tinted at the preparation stage. In this case, the technology is usually used as follows:
- mix the plaster itself in a bucket;
- draw into a large syringe (color), focusing on the divisions;
- squeeze the paint into a bucket of plaster;
- mix the solution thoroughly with a construction mixer.
Decorative bark beetle plaster is usually tinted this way. By preparing solutions of two different shades and using a little imagination, you can effectively and originally decorate rooms or facades with a colored composition.
Wall decoration with decorative plaster is becoming increasingly popular. Applying such material and painting it is not so easy, especially since there are several varieties. Therefore, it is worth considering in more detail the intricacies of the process of painting decorative plaster.
Peculiarities
Conventional cement or gypsum based plaster is intended only for partial leveling of walls. After its application, the surface is completely leveled using finishing putty and then painted, covered with wallpaper or other finishing material.
Decorative putty is different in that it already forms a ready-made beautiful pattern or three-dimensional texture.
Despite this, it is often necessary to paint it, for example, to create a single color range in the interior.
The advantages of using decorative plaster in a special aesthetics and originality of the interior. Its different types, with unique patterns, are used for finishing and decorating walls in shopping centers And office premises, various institutions and even in entrances.
In an apartment, you can use it to line the walls in the hallway, part of the living room or bedroom, and for the kitchen or bathroom you can use special grades that are protected from moisture, steam and fungus.
Decorative plaster is made from mineral or polymer components. Mineral can be based on cement or gypsum; for the latter, slaked lime is used as a binder.
Polymer There are vinyl, acrylic and silicone. Any type may contain crushed solid components of various substances: crushed stone, pebbles, marble, granite and others. It is they that, when applied, form intricate patterns; for example, the widely popular “Bark Beetle” has this property.
All types of decorative plaster are sold in the form of dry mixtures, which are diluted with water in a certain proportion and then applied to the walls. Application technologies are different; you can use a spatula, brush, rubber comb or even the palms of your hands.
Types of plaster
Decorative plaster, depending on the characteristics of the pattern, comes in two types:
- textured, which after application gives a three-dimensional pattern on the wall;
- Venetian or textured plaster, which has a finished smooth surface with an imitation of artificial stone.
Since Venetian plaster itself, after application, has fancy patterns with different shades and iridescence, then they don’t paint it. But textured types need painting.
There are several types of three-dimensional patterns of textured plaster:
- "Bark beetle" has small longitudinal grooves, resulting from the hard pebbles in the composition. In appearance, it resembles a tree eaten away by insects, which is why it got its name.
- "Lamb" The texture is filled with small grains, the surface is fine-grained and rough to the touch.
- "Fur coat" It turns out with a rough surface and fine pile.
- "Martianidae" has a complex three-dimensional pattern with spots of various sizes.
- Volumetric texture “American” granular interspersed with even spots of different shapes and sizes.
Mineral-based decorative plasters are well suited for finishing walls in an apartment; they are strong and durable. And here It is better not to use them for street work, since they are afraid of moisture, temperature changes, and sunlight.
Silicone and acrylic types can be used for both interior and exterior use.
Vinyl plaster based on polyvinyl chloride, protected from dampness, ultraviolet radiation, fungi and mold, can be successfully used in the bathroom, kitchen, living rooms and on the street. Its only drawback is its high airtightness, due to which the walls in the apartment “do not breathe.”
Paint selection
In terms of their composition, organic paints intended for decorative plaster can be acrylic, silicate and silicone. The first ones are made from acrylic polymer resins, have a drying time of 5 to 30 hours, the surface becomes matte after use.
Acrylic types plaster paints are odorless and retain their rich color for a long time.
Silicate dyes based on silicon organic resins and metal pigments form a viscous, durable film on the surface that is resistant to moisture and temperature changes. Silicone paints are water-dispersed, safe to use, and have long-lasting, rich shades.
Paint for decorative plaster can be made and mineral based. These varieties are designed for finishing concrete or brick surfaces.
Despite affordable price and a large variety of colors, mineral water-based paints have a shorter service life, than organic ones, are less protected from adverse effects. They are often used to perform Finishing work for plastering indoors and outdoors.
Oil enamel, used for painting textured plaster, is made from quartz sand, oxides of various metals, polymer and mineral pigments, giving the material different palette colors.
After painting, a durable opaque film is formed, most often with a characteristic shine.
Flaw oil paints and enamels have a strong odor, which can persist after work for a long time, even when completely dry.
Alkyd paints, like oil ones, have a sharp bad smell. Most often they work with them wearing a respirator.. Despite this drawback, they dry out faster than oil types, do not form smudges, are resistant to mechanical damage and moisture.
Coatings made from these dyes can be safely washed; they are quite popular for interior works.
Experienced craftsmen admit that the consumption of this type is less than that of others.
When choosing paint for decorative plaster, you must first take into account what type of work it is - façade or interior. Water-based acrylic, silicate and silicone types are perfect for decorating facades.
They will withstand bad weather well, are resistant to moisture and, importantly, vapor permeable.
There are a huge number of shades on sale - several hundred colors, there is a choice to suit any exterior. These paints are used for various textures of plaster: “Bark Beetle”, “Lamb”, “American”.
For interior work, acrylic, latex, and mineral water-based paints are most often used.. You can also use oil or alkyd options, but they often cause inconvenience in work and you have to frequently ventilate the room. But these paints provide a durable and bright film with intense shine.
Also, when choosing paint, you should consider its consumption.
On a rough surface the norm is one layer for various types the following:
- Oil enamel– 1 liter per 10 – 15 sq. m;
- Acrylic– 1 liter per 8 – 10 sq. m;
- Water-based– 1 liter per 10 – 18 sq. m.
However, this consumption may vary depending on the degree of unevenness; rougher textures of plaster absorb more.
Painting methods
You can paint decorative plaster yourself without any problems, both indoors and outdoors. Work begins with surface preparation. If the walls have been recently plastered, you need to wait until they are completely dry, then clean them of dust and construction debris.
It is not recommended to wash decorative plaster with a rag or sponge; an industrial or household vacuum cleaner is best for cleaning.
- Firstly, it gives better adhesion to the surface, the layers will not peel off.
- Secondly, the primer solution is able to close small pores in the decorative texture of the plaster; paint will not get there, therefore, its consumption will be reduced.
- Thirdly, the primer will strengthen the structure of the plaster itself, it will remain intact longer.
It is best to choose acrylic or polymer varieties deep penetration depending on the location - for external or internal work.
The paint is applied with a roller or brush. It is better to use a roller, as it covers a larger area and distributes the composition as evenly as possible over the surface. For it you need to take a special bath, where you periodically dip it. Painting proceeds in one motion from bottom to top. A brush is needed to paint edges, small areas, hard to reach places, where you can’t reach it with a roller.
Textured plaster usually painted in at least 2 – 3 layers, less is not enough for full coverage. Therefore, paint consumption increases. Some people dilute it with water, but the lower the concentration, the more layers will have to be applied.
Several interesting methods are used for painting decorative plaster. They all give their own unique effect.
Painting one color is the easiest way. It is done with a wide terry roller using vertical movements, and stains are removed with it. Each previous layer covers a new one.
It is necessary to paint until all irregularities are filled with a uniform color.. This method has found application in facade work.
Painting in two colors begins with a regular roller until completely painted in one base shade. After drying, you need to take a sponge or foam roller and dip it into the paint with the second color so that it lies in a thin layer on the surface. Then, with a sponge, carefully go over the protruding areas of the relief surface so that only they are painted, and the indentations retain the base color.
It is possible to paint textured walls with the effect Venetian plaster. The base layer is performed using the usual one-color coating method. The second shade is taken with a metallic sheen, for example, based on silver or aluminum powder.
You can use different colors: gold, silver, bronze.
