Decorative plaster covered with varnish and glitter. Decorative varnish - shine and protection of your plaster! Features of applying structural plaster in different techniques

Can plaster be varnished? What kind of solution should be used in the decorative finishing of plastered walls inside and outside the house? How to do it right? Those who do not understand the issues of construction and repair may not even know that this is possible.

Usually we perceive varnishing when we are talking on the processing of wood (floors, walls, furniture, interior items). Lacquer is also often used for metal work. And more for decorative finishes brick and stone. But few people know that varnish can also be used to cover plaster.

Why varnish plastered surfaces

Lacquer on plaster is applied for this:

Strengthens base materials.
Protects from influence external environments: moisture penetration, mechanical damage, exposure to chemicals.
It has antiseptic properties: it protects surfaces from the formation of fungal mold.
Long-term preservation of the original appearance of the decorative finish.
Preservation of the saturation of the colors of the painted walls.
Ensuring the indelibility of the surface, which in turn allows for reusable wet cleaning of the walls.
Emphasizes, enhances, complements the decorative properties of interior decoration.

Lacquer as a finish protective coating, decorative plaster, painted in mortar, is usually opened.

What solution to use

Depending on what kind of aesthetic qualities the interior finish should acquire, appropriate varnish products are selected. For indoor use, it is desirable to choose the safest solutions in terms of composition, which include water-soluble varnishes. But for outdoor work, you can choose a varnish on organic solvents, which is more inert to atmospheric influence.

Lacquer is classified not only by the type of solvent base, but also by the degree of haze, by the main composition, by purpose, by special properties (including exclusively decorative ones), by drying time, and so on.

In fact, under the plaster coating, you can choose almost any modern paint and varnish composition. But to throughput base materials (air permeability, but moisture resistance, first of all) has not decreased, it is still better to use a varnish intended for plastering work.

For decorative plaster you can use:

Water-based acrylic varnish is the most suitable product for indoor use, as it is odorless, non-toxic, environmentally friendly. In addition, acrylic mixtures interact well with base materials, easily stain even textured surfaces. They are used more to give the finish extra gloss. Allow tinting of the solution, both pigment and specific.

Milky shade liquid after drying forms a strong, elastic transparent protective film that does not overlap the main color. Other positive properties:

Aqueous lacquer solution with a different base, such as polyurethane. Although this varnish is usually covered wooden surfaces and from mineral materials. Polyurethane compounds have high strength, moisture resistance, good physical and mechanical properties. The solvent in the form of water ensures the environmental friendliness of the product, that is, free use inside residential premises. It is better to learn more about the possibility of using polyurethane varnish for plaster either from the manufacturer or from repair experts.
Group of facade materials. An important difference is the maximum protection of facade surfaces from aggressive influences. environment. From moisture (rain, snow, fog) and temperature changes. from the wind and ultraviolet rays. From mechanical and chemical influences.

In terms of aesthetic properties, this can be:

glossy varnish with water and dirt-repellent properties - good for textured surfaces;
matte varnish maintains the naturalness of the finish - good for embossed surfaces;
craquelure - creates the effect of "antique" paint, finishing feature - the creation of decorative cracks on the plastered surface;
mother-of-pearl varnish is used as a topcoat with a unique iridescent effect;
gold, silver, steel - in general, any solution with pigments - is used for patination, color enhancement or basic coloring of plaster;
with holographic effect.

Application technology

Lacquer work is one of the final stages of finishing. It will take a long time from the moment the repair begins before it will be possible to proceed to the finishing coating of the walls. We will not talk about direct plastering with a decorative mixture or for painting.

This work will take several days, because the surfaces need to be primed, apply a plaster solution, then paint (if required). And each stage has its own drying time. And coloring walls usually requires a minimum of two-layer processing.

Let's move on to varnishing.

To ensure better adhesion of the finishing protective layer to the base materials, it is recommended to prime the plastered walls. For this, primer compositions similar in type to the finishing solution are used (for example, aqueous acrylic). Priming is recommended at least two or three layers. In addition, primers are used:
- to strengthen the structure of base materials (deeply penetrating impregnations);
- as antiseptic to prevent the formation of mold;
- to increase water-repellent and other protective properties of the finish;
- to reduce the consumption of varnish solution.
Now let's move on to varnishing. Basically, solutions are sold in a form that is ready for application. Too thick mixtures can be slightly diluted with water (but not more than 10% of the total mass). The mixture must be thoroughly mixed before use until a homogeneous consistency. If tinting is supposed, the pigment is added according to the instructions. If the products are two-component, when mixing, we are guided by the same instructions.
Surfaces can be varnished different ways, it all depends on what the final result should be. With conventional staining, it is more convenient to use the spray method. The layer will lie more evenly, and the consumption of expensive materials can be reduced. Processing should be done several times at intervals for drying periods. To obtain a decorative effect, other painting tools are used: brushes, rollers, sponge. There are more unusual ways applying a varnish mixture to the surface, which professional craftsmen resort to.

Compliance with the rules for varnishing plastered walls will allow you to work efficiently even without the involvement of qualified builders. Subsequently, finishing for a long period will not require restoration or major replacement. But even in the case of minor troubles, it is easy to solve this problem - the old protective layer removed special means, after which a new one is applied.

Many owners of houses and cottages are interested in whether varnish can be used as a coating for plaster and which solution is best for finishing already plastered walls. These questions can often only be answered by a person who is well versed in construction and repair.

The advice of professionals will help you understand what varnish for decorative plaster is, how to choose and apply it. This will allow you to carry out repairs quickly and efficiently. The finish will be beautiful and durable.

First, you just need to figure out why decorative plaster varnish is used, whether it is possible to do without this procedure at all.
Experts say that today there are many materials for sale for internal and exterior finish. One of them is varnishing. This process is necessary for several reasons:

The materials that play the role of the foundation are well strengthened.
The finish is protected from moisture, which can penetrate the product and harm it.
Wax, varnish for decorative plaster prevent chemicals and other substances from getting inside, various mechanical damage.
Mold will not be able to penetrate the finish, develop inside this material.
The lacquer can retain its original shape very well, so the facade will be durable, beautiful long time. Manufacturers guarantee the preservation of colors, their saturation.

Thanks to varnishing, the surface can not be washed off during repeated cleaning. On the contrary, it becomes brighter and more attractive.

Solution use

When studying how to varnish decorative plaster, you should consider all kinds of means. They are selected strictly taking into account what qualities the finish should acquire.

Indoors, it is better to use products that do not cause great harm ecology and characterized by a fairly safe composition. And outdoor work can take place with the use of any varnish. It can be classified by composition, which is the main one, by decorative properties, by drying time, and so on.

Under the plaster coating, almost any composition bought in the store is well suited. The only quality that needs to be considered is that the varnish was created exclusively for working with plaster. There are many varieties of compositions presented.

Acrylic lacquer

For building or repair work indoors, water-based decorative plaster varnish is perfect. This is an acrylic composition. Its basis is water.

The advantage of the presented materials is the absence of smell. It can and should be used in various premises. Acrylic mixtures can perfectly paint over even textured surfaces, giving them the required gloss.

Acrylic varnish for decorative plaster is a liquid of delicate milky shade. When it dries up, it creates protective film, which does not affect the main color in any way. Under normal conditions, the liquid dries within three hours. If necessary, it can be diluted with water. The layer in this case will become thinner. Acrylic water-based varnish is resistant to ultraviolet and other adverse effects.

Polyurethane varnish

Another solution for interior decoration indoors is a polyurethane water-based decorative plaster varnish. Usually it is it that is used to cover wooden surfaces. The composition has high strength and moisture resistance.

The water in the composition plays the role of a solvent. It provides high environmental performance, which makes the varnish safe for use in residential areas.

facade materials

Facade varnish for decorative plaster is characterized by increased resistance to adverse weather conditions(to rain, snow, wind, etc.), as well as various chemicals.

Based on the aesthetic properties, there are several popular varieties of the presented materials. Today, facades are used for:

Lacquer is glossy. Repels dirt and water.
Lacquer matte. Suitable for embossed surfaces, can maintain a natural finish.
Craquelure. It creates an effect old surface. His duty is to create decorative cracks.
Pearlescent varnish. It shimmers very nicely. Such a coating is considered to be the final one.

There are also silver lacquers, as well as gold ones. However, they are more often used to create small accents, painting over small details.

Application

Works with varnish are transferred to the final stages of finishing. But before you start covering the walls, you need to properly prepare the base. These jobs can take a fair amount of time.

You need to prime the base first. This will give the required tenacity to the connection of the varnish with the wall material. Then you can apply the solution. Each of these actions requires a certain time for the layers to dry. If processing is carried out in two layers, it is required to color the walls.

Lacquering

It is highly recommended to prime already plastered walls for better adhesion of the final or, as it is also called, finishing layer. You need to apply two or three layers. You should also choose the right primer. It will help to avoid the appearance of such troubles as mold.

After that, you can proceed to work directly with varnish. Solutions are mostly ready-made served in stores. Mixtures that have a high density should be diluted ten percent with water. Before you start using the mixture for its intended purpose, it must be thoroughly mixed so that the consistency itself is homogeneous. If the product consists of two components or tinting is supposed, then the pigment is added strictly according to the instructions.

Depending on what the end result should be, they choose how to apply varnish on decorative plaster. For conventional staining, the spray method will be the most suitable. The advantage of this method is the ability to reduce the consumption of materials. They are not that cheap. The layer itself will be even. Take short breaks to dry the layers.

To obtain decorative effect, you must use tools such as a roller or brush. Work in this case requires more time, material costs. Of course, there are also such unusual ways correct application that are often used only by professionals.

Having considered the features that varnish for decorative plaster has, you can choose and apply the composition correctly to the surface. If you follow all the rules, you can do the job well without builders. In the future, the finish will not need any restoration or replacement at all.

To protect the finished surface, professionals recommend using varnish for decorative plaster. With its help, the base will not only be protected from possible mechanical damage and fading, but will also take the optimal appearance.

With it, the coating will take a finished decorative effect. Despite the fact that it is possible to perform work with a number of materials intended for these purposes, varnish is the most popular.

Benefits over wax

Lacquer is easier to remove from plaster than wax.

Despite the fact that the method of waxing walls has been known for a long time, it does not have such popularity as varnishing. For these purposes, a special decorative composition was used, which is significantly inferior to modern method in their characteristics.

The advantage is a uniform application that does not leave stains and streaks. In addition, waxing requires a certain technology with subsequent processing.

It is not difficult to remove plaster varnish from the wall, it is enough to treat the surface special solvent designed for these purposes. It is quite difficult to clean the textured area from wax, especially since subsequent painting will be impossible, since adhesion to other surfaces in this case is minimal. Most likely, you will have to remove the layer mechanically, partially damaging the plaster.

Do not forget that varnish is much stronger than wax, so it can perform protective functions much better.

Beneficial features

A layer of varnish will further strengthen the coating

Any material can be used for these purposes. However, it should be borne in mind that if it is necessary to preserve the useful natural properties of the wall regarding the passage of air through its structure, it is recommended to use a special composition intended directly for decorative plaster.

In addition, it will be possible to get a number of other advantages that are unusual for other types of paints and varnishes:

Strengthens and reinforces the base material of the wall.
Protects from destructive external influences: penetration of moisture, mechanical damage, aggressive chemically active substances.
Protects the wall from the appearance of fungus or mold on it.
Increases the period of the original appearance of decorative plaster.
Saves saturated colors and invoice.
Allowed to do wet cleaning grounds.
Enhances the appearance of the interior surface.

Selection of the optimal composition

First of all, it is necessary to take into account the compatibility of the plaster varnish with the surface on which it will be applied.

To facilitate the selection, you can be guided by the table below.

For interior decoration, water-soluble varnish is quite suitable.

In addition, one must take into account its aesthetic properties in combination with the interior that the surface will have to accept. For example, for application on a wall indoors, it is recommended to use a safe in its own way chemical composition solution.

One of the most common and affordable in terms of price characteristics is a water-soluble varnish. The treatment of street walls is carried out with a composition with an organic solvent, which is more resistant to atmospheric influences.

In addition, the classification occurs not only by chemical and organic composition, but also according to the degree of haze, purpose, decorative features, drying time. To date construction market presents wide choose various compositions, which can be applied to any surface. But, as mentioned earlier, in order to maintain breathability and moisture resistance, it is best to use varnishes that are intended directly for working with textured plaster. For more information on how to apply varnish on plaster, see this helpful video:

With the help of varnish for plaster, you can get a glossy surface without much effort. It will not require periodic maintenance. long time.

acrylic water based

Considered the most the best option indoor use. It has no pungent odor, non-toxic, environmentally friendly.

In addition, the acrylic composition perfectly interacts with the material of the wall surface, is easily painted, while maintaining the texture. It is intended to increase the effect of gloss, it is well tinted both pigmentally and specifically.

Despite its milky hue when applied, after the surface dries, a protective layer forms on it, which does not distort the main color.

In addition, water-based acrylic lacquer has several other distinctive characteristics that are unusual for other compositions:

Composes well.
Possesses high-quality adhesion.
Resistant to sunlight, moisture, cleaning chemicals.
Does not contain organic solvents.
If necessary, it can be diluted with plain water.
At room temperature dries within 3-4 hours.
Used for walls made of various materials.

polyurethane

Polyurethane varnishes are very durable

Water-based varnish with polyurethane addition is mainly used for application on wooden or mineral-based walls. However, on decorative plaster, it does not lose its properties and serves with the preservation of all useful characteristics.

Differs in the high durability, moisture resistance, has excellent physical and mechanical indicators. The absence of a solvent in its composition guarantees good environmental friendliness and the possibility of using it indoors.

Regardless of the chosen varnish, when applying, it is necessary to strictly follow the rules for varnishing textured surfaces. This will allow you to achieve the best result even without resorting to the services of specialists.

Competent and correct handling will allow for a long time to forget about the repair or replacement of damaged areas.

Decorative plaster is a great alternative to traditional wallpaper. Initially, it has a white or gray color, which allows homeowners to show imagination and create an interior with paint in original style.

What paint to choose

To finish 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 fluctuations well and reliably protect plaster from atmospheric precipitation. Sold in the form of a white composition, which is tinted in a special machine or independently in accordance with personal preferences. The consumption of different types of paint on decorative plaster is slightly different. For single coat acrylic paint approximately 170-200 g / m² will be required, silicate - 150-300 g / m².

When working indoors, water-based, acrylic or latex paint. Water emulsion requires a two-layer application, after which the plaster acquires a matte surface.

Acrylic coatings are used mainly in rooms with increased level humidity - bathrooms or kitchens. They are more durable than water-based paint, therefore also used for finishing textured plaster in the corridors.

Latex paints practically do not differ in technical characteristics from acrylic ones. They are universal and fit well on any base, including cement and gypsum textured plaster.

From a technical point of view, the choice of any of these colors is not fundamentally important - the range of shades allows you to implement a variety of design ideas, so basically customers are guided by the price of coverage. The only thing you should pay attention to 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;
blur.

The coloring technology is not difficult even for beginners - it is enough to have a standard set of painting tools:

roller - the length of the pile is selected depending on the texture of the surface;
brushes of different widths;
paint tray.

For painting large surfaces, it is convenient to use an airbrush. This greatly improves the speed and quality of work. Before you start painting, you must wait until the plaster layer has completely dried, and then treat it with a primer. deep penetration otherwise the paint may blister and crack.

tinting

The easiest way to paint plaster, used to obtain a basic shade. Decorative plaster is sold in the form of a composition of white or gray colors, which is tinted by adding a coloring pigment. Its quantity depends on the required color saturation. Kohler is added to a container with plaster and intensively mixed until it acquires a uniform color.

The advantage of this method is that the plaster layer has the same color throughout its thickness and, in the event of small chips and scratches, they will be almost imperceptible. In addition, after drying, the plaster already has a color and the need for additional painting works disappears.

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 making sure that all the depressions and protrusions of the plaster are painted over. Then excess paint, in the form of smudges, is collected with a brush.

When working with a roller, the coloring is done in vertical stripes. Each subsequent strip is rolled with an overlap of several centimeters over the previous one. For uniform painting of the wall with a wide brush, the coating is applied first vertical movements, then overlapped by horizontal ones. You can also first paint over the wall with a thick layer of paint with a brush, and then evenly distribute it over the surface with a roller.

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, the paint is applied in one pass, as described in the previous method. Smudges 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 coat or a sponge. The roller is rolled in the tray in such a way that it remains thin layer paints. After that, they lightly walk along the protruding parts of the decorative plaster, as a result of which the recesses on the surface remain in their original color, and the protrusions acquire a different shade. The 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 carried out 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 expressiveness to the surface, gold, silver and bronze colors are used, and glitter is also used.

Lightening plaster by blurring

The method is suitable for indoor use. At first small plot surfaces are painted in one pass with a thinned water-based paint. Thereafter, in a circular motion wet sponges pass over the surface, blurring 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 a different shade using one of the above methods.

There is another common method to create 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 with the help of a power tool, the surface of the wall is sanded, removing a thin layer of protruding sections along with paint. This operation can also be performed with a spatula, working “on the swipe”.

Creating the effect of Venetian plaster

In the classic version, Venetian plaster imitating the surface natural stone, contains a crumb of marble, granite or malachite. The cost of coverage is quite high, but this method allows you to create an effect Venetian plaster I use only gypsum mixture, paint and glazing coating:

The wall is painted in one pass with a long pile roller so that all the recesses of the plaster are filled with paint.
As the second shade, paint with a metallic sheen is used. It is diluted with a universal primer or other transparent base in a 1: 1 ratio.
With light movements of a small foam rubber roller, they walk along the protruding sections of the relief. In this case, it is necessary to ensure that there are no streaks on the surface.
At the next stage, the plaster is coated with acrylic varnish. It is diluted by 30% with water and glitter is added to create a shimmering effect, at the rate of 1 teaspoon per 1 liter of varnish. The resulting mixture is treated with a plaster surface using a foam roller. During operation, the varnish must be stirred regularly, 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 processing decorative plaster

To make the appearance of the plaster more spectacular and create an additional protective layer, you can use wax, varnish and various glazes.

Wax creates a protective waterproof coating that gives the surface shine and bright shade. Suitable for any type of plaster, looks especially impressive on the Venetian. On sale there are both transparent and colored compositions. Before application, dust must be carefully removed from the base. Plaster coating is done at one time without stopping. The setting time of the wax is about 4 hours, during this period you can still correct the resulting flaws.

Lacquer is a single layer finish. 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. To 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 - glazing translucent composition for finish coat paint to make smooth transitions colors. It is applied to drawing on a plain and relief surface as indoors, and outside. Works can be carried out at a temperature of less than +10°C. The coating is applied with a sponge or a special mitten with strokes.

As a rule, many people associate surface varnishing with wood processing. For example, wooden furniture, walls or floors. Not many people know that varnishes are also used for plastering. And yet, professionals strongly recommend varnishing plastered walls. This is essential to prolong the life of the surface and its reliable protection from pollution.

Plaster is considered a finish, and many do not know that it can be additionally protected and strengthened. What solutions are used to coat decorative finishes indoors and outdoors? One of effective means- This is a varnish for plaster. This article will discuss why varnishing ordinary or decorative plaster, which varnish is better to use, and how to properly varnish.

Some believe that it is necessary to varnish wood, furniture, floors, interior items, metal surfaces. However, often varnishes are used to cover brick, plastered walls and stones.

Why you need to varnish the plaster

Many are interested in whether it is possible to coat the plaster with varnish, and why is this done? The lacquer is used for both ordinary cement-sand and decorative plasters, thanks to lacquering the following goals are achieved:

the surface of building materials is strengthened;
plaster is protected from various negative factors, for example, mechanical stress, penetration of moisture and water, the influence of destructive chemicals;
the base acquires antiseptic characteristics, so mold, fungi, and other microorganisms do not appear on it;
decorative trim retains its original attractiveness for a long time;
the shade of the painted wall retains color saturation for many years;
the surface of decorative plaster becomes indelible, so wet cleaning can be carried out many times;
the decorative qualities of the interior will be enhanced and emphasized.

Typically, decorative plaster varnish is used as a topcoat, applied to either a painted finish or plain plaster.

What composition is better to use

When deciding to varnish a surface, many people wonder what kind of varnish can be applied to decorative plaster? It depends on whether external or internal walls, as well as what characteristics the finish should receive. If the varnish will be applied inside the room, then it is necessary to select the safest and most environmentally friendly compositions. Generally, a water-soluble formulation is preferred. A water-based acrylic lacquer is well suited for this purpose. And if it is processed outer layer plasters, then varnish compositions based on organic solvents are used. These products are highly resistant to harmful weather conditions.

Varnishes are divided according to the type of base, as well as according to the gloss index, according to their intended use, technical specifications, drying time, environmental friendliness, and other indicators. Experts say that almost any type of paint and varnish product can be used to cover the plastered layer. However, in order not to reduce the throughput of the surface, as well as moisture resistance and breathability, it is necessary to give preference to those varnishes that are designed specifically for plaster.

The best option for protecting decorative plaster is acrylic varnish, which has water base. It is used indoors, is environmentally friendly, non-toxic, harmless to humans, and has no unpleasant odor. Acrylic compounds have good adhesion and interact well with the plastered surface, they are able to paint ordinary, smooth bases and textured surfaces. Acrylic lacquer for decorative plaster is used to make the finish glossy, visually attractive. Acrylic products can be tinted with pigment and specific components.

Acrylic-based mixtures have a milky tint; after drying, the solution forms a transparent, strong and at the same time elastic film that does not spoil the main shade of the finish. Among the advantages of acrylic lacquer products are the following qualities:

excellent adhesion to different types materials;
high resistance to household cleaning chemicals, humidity and ultraviolet rays;
safety, as there are no organic solvents in the composition;
at room temperature, the mixture dries in about three hours;
if necessary, the composition can be diluted with plain water;
can be used for plaster, stone, brick, and other building materials.

Acrylic lacquer for plaster is not the only option. In addition to it, polyurethane varnish composition is very popular. It is usually used to protect mineral species materials and wooden bases. Polyurethane blends have high rate strength, resistance to moisture, and excellent physical and mechanical characteristics.

Water is used as a solvent for the polyurethane mixture, which makes the solution environmentally friendly and can be safely applied inside the room in which people live. It is worth noting that not every polyurethane mixture is suitable for varnishing decorative plaster, it is necessary to read the manufacturer's instructions to make sure that the materials are compatible.

A separate group of paint and varnish products is facade materials. They have the maximum indicator of protection against the adverse and aggressive effects of precipitation and the environment. Facade varnishes reliably protect external plaster from snow, rain, fog and temperature changes, as well as from the influence of ultraviolet rays and strong wind. Facade varnish compositions provide protection against chemical and mechanical influences.

Glitter Varieties

Manufacturers offer different varnish solutions that differ in their aesthetic properties:

glossy compositions with dirt and water-repellent characteristics. This variety is great for exterior and textured bases;
matte varnishes are more often applied to embossed surfaces, on which they maintain naturalness as much as possible;
craquelure create decorative cracks on the plaster, the surface acquires an antique effect;
mother-of-pearl solutions are used as a finishing layer, they have a very attractive, iridescent, spectacular sheen;
steel, silver, gold lacquer mixtures contain pigments of the corresponding color, are often used either as the main layer of paint, or as a shade enhancement or patination;
compositions that have a holographic effect create a fantastic, unique look of an iridescent surface.

Application rules

In order for the varnish to last as long as possible, you need to adhere to certain rules and recommendations for applying the composition. It usually takes several days to process the walls, because the surface is first primed, then the plaster is applied, after which, if necessary, a layer of paint, and only after it has dried, the walls are varnished. At each of these stages of finishing, it is necessary to withstand certain time for drying. When coloring, experts recommend applying the mixture in at least two layers.

Before applying a layer of varnish or primer before varnishing, the surface must be thoroughly cleaned. Removes all contaminants such as dirt, dust, old finish paints, greasy spots, crumbling areas, and more. After cleaning, it is desirable to prime the plastered walls, which guarantees the best adhesion of the final layer of varnish to the surface. The primer must have the same composition and base as the varnish used. For example, if acrylic varnish is used, then the primer must also be acrylic. By priming with two or three layers, the following advantages are achieved:

materials are strengthened and protected from rapid destruction;
an antiseptic coating is created that protects against the appearance of fungi and mold;
the water-repellent characteristics of the finish are improved;
the consumption of varnish applied over the primer is reduced.

After priming, you can proceed to varnishing the walls. Usually in stores they sell ready-to-use formulations. If the mixture is very thick, it can be thinned (following the instructions) with either water or thinner, depending on the composition of the varnish. It is allowed to dilute no more than 10% of the volume of the varnish solution. Before application, the mixture must be thoroughly stirred so that its consistency becomes homogeneous. You can add pigments for tinting to it, in accordance with the instructions. If the varnish is two-component, it is also prepared according to the instructions.

You can apply varnish mixture different methods. The fastest, most convenient and economical option is spraying from a spray bottle. The solution will lay down in an even layer, and its consumption will be reduced. To get a decorative effect, you can apply varnish with a sponge, roller or brush. It is advisable to varnish with two or three layers, to achieve maximum protection. Before applying the next layer, it is necessary that the previous coating has time to dry. You need to work with gloves, goggles and a respirator to protect the skin, eyes and respiratory organs.

To create the effect of brickwork or aged stones, it is well suited decorative plaster Travertine (Travertino) or Marmorine (Marmorino). As a result of applying several layers with a special tinting and a certain composition, a coating thickness is achieved, which, at the next stage of processing, is divided into sectors of the desired shape - stone or brick, by scratching and partial sanding.
Distinctive feature The use of decorative plaster in creating the effect of stone or brickwork is the thickness of the coating. Very often, when creating a design project, one has to abandon one or another excellent and relevant idea due to the fact that one or another coating has a large thickness or size and does not fit into the existing dimensions. The thickness of decorative plaster is several times less and you can safely use it in a variety of rooms without fear of losing space.
