Experts recommend stone varnish. Choosing a varnish for stone and concrete for exterior and interior work Paint or varnish for facade stone

Varnishing is required for 2 reasons. To protect mineral finishing materials from destruction under external influences. It also allows you to create an original exterior for a stone with the effect of a wet stone is quite in demand, and in external and internal decoration. Read more about this tool in the article.

What to choose?

The answer depends on what type of stone coating needs to be processed and what features it has. For example, paving slabs, bricks, finishing are treated with a product that will protect against atmospheric phenomena. In addition to moisture resistance, the mixture must withstand temperatures, ultraviolet, wind, and mechanical stress.

The protective agent must be reliable in order to maintain the strength and indestructibility of mineral materials for a long time. Stone, tiles and ceramics in rooms are less exposed to atmospheric conditions, but the microclimate in the rooms and the intensity of use can influence.

Lacquer for natural stone with a wet effect allows you to create a protective film that emphasizes the texture and saturation of the shade, and there are products that give it a slight silkiness. Wet stone effect acrylic lacquer suitable for stone surfaces. It is water-based and solvent-based.

Water-based product suitable for interior decoration. This mixture has the best performance characteristics, since it does not contain chemicals, which cannot be said about solvent-based varnish. Because of this fact, toxicity increases. When working with these mixtures, you should remember safety precautions and use protective equipment.

Properties

Wet stone effect stone lacquers have the following properties:

  1. Possibility of use for external and internal work.
  2. Strengthening the surface and structure of bricks, tiles, concrete, stone.
  3. Weather protection.
  4. Surface hydrophobization and protection against moisture ingress.
  5. Decorative function: rich shade, shine.
  6. High level of adhesion.
  7. Insensitive to chemicals, UV, temperatures.
  8. Long service life.

Thanks to them, the decorative finish of walls, floors or sidewalks lasts longer and looks more interesting.

Usage Method

Wet stone effect stone varnish is sold ready-made, in a liquid substance. Stir the product before surface treatment. With the viscosity of the substance, it is necessary to dilute no more than 10% of the total volume. The thinner used is white spirit.

The mixture is applied with a paint brush, roller or sponge. For a smooth surface, one layer will be enough, and for a porous one, 2-3 is required. There are 6-8 hours between stages. Even when applying a water-based varnish, it should be used There should be no open flame near the place of work, since the material is flammable.

It is important to thoroughly ventilate the room during and after work. The surface is preliminarily cleaned of dirt, grease stains, dust, mold, and then dried. If paving slabs are to be varnished, it is necessary to check that the canvas does not rise from below. The design must be free of fragile areas.

Expert evaluation

Many experts recommend using a special stone polish with a wet effect. Reviews of experts are mostly positive, but there are exceptions. For example, if the substance is thick, it is diluted with water: no more than 10% of the volume, but when painting, white smudges and air bubbles appear.

To eliminate this drawback, experts recommend using a solvent. Then you do not need to dilute and use the finished one. After stirring, the product should stand for 5-10 minutes for the bubbles to settle. Compatibility of the compositions of products for cleaning stone surfaces and varnishes should be taken into account. It is necessary to monitor the temperature (from +10 to -20 degrees).

If you correct the shortcomings correctly, then the next work will be of high quality. It is not difficult to make a strong, stable construction from mineral materials. It is only necessary to use a high-quality stone varnish with the effect of a wet stone. The coating will be protected from external influences. Due to this effect, there is a feeling of purity and brilliance, as if it had just rained.

What varnishes are still in use?

The advantage of varnish is the possibility of using it for interior and exterior decoration. It can be used in all climates as it is resistant to temperature and moisture. The following types of funds are used:

  1. Polymer. This mixture is waterproof. In addition, after treatment, the surface dries quickly. This saves time when a large area needs to be covered. It is used in external work to give the material decorative properties.
  2. Polyurethane. Used in the construction industry, suitable for processing various surfaces. An organic solvent is mixed with polyurethane. When the agent dries, a colorless film forms.
  3. Silicone and acrylic. Used for decorative purposes. Their main purpose is interior decoration. Moreover, the surface can be stone, brick, decorative. The film provides moisture protection.
  4. Epoxy. Such varnishes are acceptable for processing wooden products. It is considered harmless, so it is used in furniture coating and interior decoration.

Thus, varnishes have many advantages. The effect of a wet stone looks original, but to create it, you need to choose the right tool, as well as correctly stain.

The oldest and especially popular in modern construction is natural stone. The demand for this material is due to strength and durability, but it must be remembered that almost all rocks have the ability to absorb liquids. In the articles we talked about the methods of protection, cleaning and processing of stone surfaces. But when using natural stone, you need to know what to look for when choosing a special tool, depending on what tasks it will perform.

What is impregnation for?

All kinds of protective compounds are usually used in the following situations:

  • The stone is exposed to external factors. In this case, the material can be both inside the building and on the street. Chemicals, detergents, paint, water damage the coating very much. As a result, stains appear on the stone, which are quite difficult to remove.
  • Facing burnout occurs. Exterior finishes are most exposed to sunlight, losing their original color.
  • The stone is overgrown with moss, mold and fungi. If their appearance is not prevented, then over time the stone will gradually collapse.
  • White spots appear on the surface. Efflorescence negatively affects not only the appearance of products, but also leads to damage to the structure of the material over time.

Types of protective drugs

Impregnation must be chosen taking into account the negative effects that will be exerted on the stone during operation. Today, chemical manufacturers offer to use different types of impregnations. The composition fills the pores and does not allow moisture to destroy the natural material. In addition, the stone becomes resistant to gasoline, salt, chemicals and other aggressive substances and retains its attractive appearance for many years.

Depending on the composition, protective impregnations are of the following types:

  • latex-based - used to prepare stone for painting;
  • containing chemicals - used to remove stains and rust of various origins;
  • silicone - serve to protect stone surfaces from the effects of rain, snow, sun and temperature extremes.

Characteristics of different compositions

Quite popular among buyers are solutions that create the effect of a wet stone. This impregnation is used to protect against water and the appearance of dirty spots. Experts recommend applying the product in order to improve the appearance of the product and emphasize the natural structure of the material. And also impregnation "wet stone" is used to enhance the color of the stone, eliminate microcracks and more.

Such solutions are consumed quite economically and are easy to use. Treatment with such impregnation provides reliable protection against external influences, prevents aging and rapid destruction of natural material. The surface becomes bright and glossy, much fresher and darker than the original color. Such impregnations are used on external and internal surfaces - cladding, countertops, floor coverings, monuments, sculptures. It is undesirable to use "wet" stone impregnation with a glossy effect on paving stones.

Other popular means are water repellents. Their purpose is to protect the surface from the absorption of various liquids. It can be water, tea, juices, coffee and others, which, when penetrating into the structure of the stone, spoil its appearance and aesthetics and contribute to the premature destruction of the material. Water repellents are safe for human health and do not harm the environment, they dry quickly and are deeply absorbed into the stone. At the same time, the thinnest film is formed on the surface, which prevents the penetration of moisture and oily substances, the appearance and growth of mold. The stone becomes more resistant to sub-zero temperatures, while maintaining the appearance of the material and its breathability. Facades lined with natural stone and treated with water repellents are much easier to care for in winter. However, it is better not to use such impregnations on surfaces subject to prolonged exposure to water, such as paths and sidewalks. It is important to remember that a stone coated with a water repellent cannot be painted if necessary, so the composition should be applied last.

Often, as a protective agent, consumers choose stone varnish, which is glossy and matte. The first makes the coating brighter, as if wet. The second type of varnish is usually used for floors and stairs in buildings with high traffic.

Protective varnishes are quite deeply “absorbed” by the stone, making it resistant to external influences and weather disasters. Such funds are of the following types:

  • polymer - used for indoor and outdoor work;
  • polyurethane - mainly used for impregnation of stone facades, tiles in swimming pools or paving, as it makes the surface impervious to water;
  • silicone and acrylic - enhance the decorative properties of the stone, are used for finishing outdoor elements and varnishing large areas indoors.

The surface coated with such a composition becomes more durable and is not subject to wear. Such impregnations have minimal flammability, are resistant to low and high temperatures, and are suitable for use in wet rooms (baths, bathrooms and shower rooms), outdoors and in public places. Varnishes contain chemical compounds, so when working with them you need to be careful.

There are special tools not only to protect the stone and improve its external characteristics. Anti-slip impregnations help to make the surface safe and prevent people from falling on granite, marble, ceramic floors. Such compositions are made on the basis of water and are very easy to use. When conducting primary processing, experts recommend testing in an inconspicuous area, as the stone may lose its brightness.

Today, manufacturers offer many new products, among which are special compounds for protecting stone from graffiti. Such solutions evenly cover the surface and do not allow paint from a can to penetrate into the structure of the stone, and the removal of the pigment becomes hassle-free - it is enough to treat the contaminated area with a steam jet.

Such impregnation is used for natural and artificial stone, as well as for brick, concrete and other materials with a porous structure. The anti-graffiti preparation contains water, silicone and polymers. In addition to the main purpose, this composition makes the stone resistant to the destructive effects of wind, water, temperature changes, the treated surface does not turn yellow, does not stick and becomes a little brighter. It is not recommended to use anti-graffiti impregnation on polished and glazed surfaces. This will result in a loss of brilliance and brightness. The paint-resistant coating needs to be renewed periodically as it is quite unstable.

If you need to save the stone without streaks or film formation, then it is better to use a tool that does not create any effects. Impregnation quickly penetrates into the depth of the stone, so a protective layer is formed inside. After applying the composition, the material does not change its color and texture, but dirt and water do not penetrate into its structure. Dust, liquid, oil accumulate on the surface and are removed with conventional detergents. Such impregnations are indispensable for the treatment of countertops and floors in the kitchen, in the hallway, bathroom and other areas where the stone is regularly exposed to quite severe pollution and requires constant care.

When choosing a composition, it is important to remember that impregnating agents are not always able to protect the stone. Under the influence of external factors, any composition gradually loses the properties declared by the manufacturer. Therefore, to maintain the good condition of the natural material, it is necessary to apply protective impregnations regularly. The refresh rate depends on the original structure of the stone. For example, it is desirable to cover more porous rocks and surfaces subject to strong mechanical stress with a protective solution every two years, and for a dense and less loose stone, one treatment per five years will be enough.

All construction and repair work with concrete, stone, granite and similar materials requires a quality coating. With the help of special compositions, not only decoration is carried out. This allows you to protect the material from external influences and significantly extend its service life. One type of coating is stone varnish, which has many advantages. In order for stone varnish to provide maximum results, it is necessary to pay attention to the main types and composition when choosing.

The main advantage of the lacquer is that it is suitable for indoor and outdoor use. It can be used in any climate, as it is resistant to temperature and moisture. With the help of varnish for stone and concrete, you can protect the material as much as possible from mechanical and physical impact, because the coating has a high level of wear resistance.

If we talk about construction work, polymer varnish is most often used here. A distinctive feature is increased water resistance. In addition, this coating dries very quickly. This saves a lot of time when working, especially when you need to cover a large area of ​​concrete. Such a varnish for a concrete floor is simply irreplaceable, because it perfectly resists not only moisture, but also cold.

It is often used for outdoor coatings due to its decorative properties. This allows you to maintain the bearing capacity, the surface will retain its appearance for a long time, and will not fade.

Absolutely for any material that is used in construction, polyurethane varnish is suitable. It is used as follows: polyurethane is added to an organic solvent. When the substance is applied and dries, it forms a colorless film. In order to change the color of the coating, it is enough to add paint of the desired color.

It is more often used for stone in outdoor work, which allows you to achieve the effect of wet stone on the surface.

It is also used when working with concrete, brick, decorative and artificial products. This maximizes the durability of the material. Also, polyurethane varnish for concrete will increase waterproofing and anti-corrosion properties.

Silicone and acrylic varnishes

For decorative work, both silicone and acrylic varnish are suitable. It is used for varnishing at internal works. It can be a stone, brick, decorative surface. Thanks to the film that forms on the surface, complete protection against moisture is provided, in addition, the substance does not lose its original appearance and does not turn yellow.

You can easily achieve the desired texture and color, it can be a matte varnish of any shades, just add a special paint. Despite the fact that the substance has high protective characteristics, it is very rarely used in outdoor work. This is due to the high price category. More often used varnish on concrete for floors and walls, as it provides maximum protection.

Epoxy varnish is also used for decorative work, but this substance is intended for surfaces and wood products. It is absolutely harmless, which allows it to be used to cover furniture and for interior work.

Thanks to this coating, the material retains its natural texture, but at the same time provides maximum protection against moisture and mechanical strength. The substance has a high gloss level when applied.

In addition to the advantages, some disadvantages should be noted. This substance does not have high elasticity. Also, working with it requires compliance with the technological process of preparation.

Properties

In addition to protective characteristics, varnishes also differ in decorative properties. It depends on what substances are present in the composition. They are divided into two types:

  1. Glossy, semi-gloss effects, with the help of which the wet stone effect occurs.
  2. Matte and semi-matt effects suitable for high traffic floors.

Both the first and second types have almost the same properties. When it is planned to work with a surface, for example, a fireplace or stove, it is necessary to take into account the temperature regime. You should also take into account in the work the surface, which has a large permeability.

Coating properties:

  • Maximum resistance to moisture and aggressive environment;
  • Due to the fact that the substance penetrates into the processed material, wear resistance increases;
  • Resistance to external factors, high temperature and low;
  • Maximum surface strength;
  • Minimum flammability;
  • Long service life.

How to work with material

  1. When working, it is necessary to observe safety precautions and have protective equipment.
  2. After the work in the room is completed, it must be well ventilated.
  3. Before applying the substance to the work surface, it must be prepared. The surface must be free of dust, dirt and moisture. If necessary, the surface is primed.
  4. The maximum allowable temperature at which you can work with the substance is 35 °.
  5. Can be applied with roller and brush. When applied to a large area, sprayers are used.
  6. For maximum effect, two coats of the product are applied, especially if the exterior stone product is applied to a porous surface.

Conclusion

Regardless of what work is ahead, you should always take into account the features of the surface on which the varnish will be applied. The characteristics of the composition allow it to be used under any climatic conditions, even at high humidity, which preserves the long service life of the products.

Lacquer can be used on floors, walls, ceilings, as a base, for decorative finishes. The main thing is to approach the choice of substance and the application procedure with full responsibility, then the surface will be protected as much as possible and will have a long service life.

Overview of varnishes for stone (2 videos)


Wild stone is a practical finishing material. It is inexpensive, has a presentable appearance, its surface is easy to clean. With the help of wild stone, you can decorate both the internal and external walls of the house. If this material is varnished, it will look more impressive: its edges will become much clearer, and the color will become brighter.

How to make the effect of "wet stone"

The finish of the plinth and facade will be more attractive and interesting if the wild stone is covered with a product that provides the effect of a “wet” surface. This property has a varnish "Olympus". It is made on an acrylic basis and gives a transparent semi-gloss sheen. The varnish can be used for interior and exterior decoration: it increases the frost resistance and moisture resistance of the finishing stone, fills the smallest pores of its structure, thereby preventing the accumulation of dirt in them. "Olimp" is non-toxic, has antibacterial properties (prevents the development of mold and fungus), does not have a strong odor.

Before applying the covering composition, it is necessary to prepare the surface of the finishing material. If there are inclusions of lime, cement, plaster mortar on the wild stone, it is recommended to use a remover from the same manufacturer to remove them: OLIMP. The tool is called "Flushing efflorescence." After cleaning the surface, you can start applying varnish. You can work at a temperature not lower than + 10 ° C. Drying time of the coating - no more than 1 hour. Stone processing can be done with a brush or roller.

What varnishes to cover a wild stone

For interior decoration, you can use Tikurilla matte acrylic lacquer. To obtain different shades, you can add color to it. It is necessary to cover the finishing material until the varnish is no longer absorbed. It is best to spray it with an airbrush: the coating will be uniform, the smallest pores will be filled. After 24 hours, the varnish will dry, but if color has been added to it, the applied layer can be scratched quite easily.

To get a durable coating that cannot be damaged by sharp objects, you can use colorless quick-drying car enamel. It comes in the form of a spray, which is very convenient for stone processing. This option for processing wild stone is suitable for outdoor work. Enamel is water-repellent, durable and strong.

Instead of paints and varnishes, you can use the Lithurin 2C impregnation. This tool penetrates deep into the stone and polymerizes in its pores, which provides high-quality protection against moisture and abrasion. The surface covered with Lithurin 2C does not darken, does not peel off. In addition to wild stone, the impregnation protects and strengthens the seams well.

Good afternoon! Interested in varnish KO-85. Is it suitable for processing countertops made of artificial stone? Where are you located in Zaporozhye?

Answer: KO-85 is an organosilicon varnish, which (according to the instructions) can be applied to metal, concrete, glass, karmic surfaces. Can this varnish be applied to the surface of artificial stone. This brand of varnish is used as an independent coating or for the preparation of Enamel - KO-814 (by introducing 5% aluminum powder into the composition). The varnish itself is used for corrosion protection of metal structures during their operation at elevated temperatures up to 250 degrees. For KO-814 enamel, the maximum operating temperature reaches 400 degrees.

On porous surfaces (e.g. concrete, plaster) pure varnish must be applied in three coats. On a firm surface - in 1 or 2 layers. When applied in multiple layers, Lacquer KO-85 changes the color of the stone surface. Many refer to this change as the "wet rock effect". Lacquer can also be used for these purposes. The surface before drawing has to be degreased, cleared of dust and dirt, it is perfectly dried up. This directly affects the adhesion of the varnish to the surface of the material.

Organosilicon varnish KO-85 has a pronounced hydrophobicity. Already after applying the first layer, the surface acquires water-repellent properties upon contact with water.

This varnish is frost-resistant and can be used to protect products and structures operated at temperatures down to -60 degrees. Also, the varnish perfectly tolerates negative atmospheric influences, and painted products can be used outdoors.

If your goal is to protect artificial stone from the negative effects of aggressive substances (oil, liquid fuel, saline solutions, acid), then the best way to cope with the task is not varnish, but enamel KO-814 based on this varnish. To protect the stone from mechanical damage, you can use other types of varnishes, for example, based on polyurethane or epoxy resin.

The kitchen is tiled with natural stone. What is the best varnish for her to use and where can I buy it in Balashikha (Schelkovo)? Is it possible to give the varnish the required color?

Answer: For natural stone tiles, you can choose varnishes on such film formers as:

Acrylic polymer varnishes for stone. Are issued decorative and protective or protective on the basis of copolymers of acrylate, polystyrene. Such varnishes dry quickly, penetrate deeply into the structure, thereby increasing the strength of the stone tile and its wear resistance, and protect against corrosion. Most of these varnishes are characterized by resistance to aggressive environments (alkaline and saline solutions, fats) due to this they are excellent for covering stone floors in the kitchen. Decorative and protective acrylic varnishes may contain wax, which increases the water-repellent properties of the coating. There are matte, semi-matte, glossy. Acrylic varnishes give the coating the effect of "wet stone".

Polyurethane varnishes for stone. Designed to strengthen the surface strength and resistance to abrasion of coatings made of stone, concrete, asbestos (refer to protective varnishes). More often they are used to cover outdoor floor materials (paving slabs, concrete paths, etc.). In order to increase strength and durability, they can also be used for stone floor tiles in the kitchen. Usually, when applied, the coating is given a semi-matte texture. With multi-layer coating, you can achieve a glossy effect. Varnishes are produced colorless or colored.

Silicone and silicone-acrylic varnishes for stone. They are characterized by high decorativeness, moisture resistance, durability (do not lose color, do not become cloudy, do not turn yellow). This type of varnish is more expensive than those listed above and is better suited for decorative stone coating indoors. There are matte, semi-matte, glossy, transparent and colored, with the effect of a wet stone, with wax.

To increase the contrast and expressiveness of the texture of natural stone, it is coated with special impregnations. After drying, the stone is covered with a colorless varnish.
