Varnish for stone

Traditional varnishes are designed for impregnating wood. However, there is a whole group of varnishes, the purpose of which is to protect concrete and bricks. Today, a lot of lacquer producers are known, among which the consumer can choose himself. Popular are the varnishes of well-known manufacturers "H & C", "Sherwin-Williams", "Promo", "KrasKo", "Olympus", etc.

Varnish for stone is designed for protection and impregnation of concrete. It is used when it is necessary to obtain a strong coating, which at the same time would be transparent or create the effect of a natural wet stone. After drying on a hard surface, a high-quality varnish should come to this state.

Lacquer for stone based on polyurethane is a particularly strong composition for the protection of concrete. It is used for indoor and outdoor works. It is extremely easy to apply it to hard surfaces, it is very resistant to chemical and physical stimuli, high humidity and sharp temperature changes. When deposited, the effect of wet stone is observed: the surface even in a dry state looks slightly moist and overflows into the sun.

Varnish for natural stone is used mainly for protective purposes. They impregnate surfaces of cement, concrete, decorative stone, brickwork, finishing tiles. In addition, varnishes are used as a finishing coat for these types of coatings. The composition shows well the texture and hides the scratches on the surface of the stone.

Luck on the stone has a variety of properties. It is a one-component polyurethane compound, the process of solidification of which takes place under the influence of air and moisture. The varnish deeply penetrates into the microcracks, de-dusts the surface and makes it even stronger. The coating provides an excellent barrier for protection from the effects of the environment.

After impregnation with varnish, the stone surfaces in operation become much more uncomfortable: they withstand the most severe conditions (they are not afraid of temperature changes from -90 degrees to +50), they are resistant to high humidity, they do not lend themselves to moderate mechanical damages.

Stone varnish is sprayed onto the surface and distributed with a special brush or roller with a velor or short coat. For internal work, the varnish must be applied in a well-ventilated room, at a temperature of at least zero and not more than thirty degrees. Stone and concrete are pre-cleaned of all substances (liquid, plaque, dust) on its surface, ground, re-dusted and dried.

The stone to be treated can be varnished in several layers, each of which is applied only after the previous one has dried completely (after about 4-5 hours). The drying time of the varnish depends on the air temperature: the lower it is, the longer it will take.

Before starting work, it is recommended to make a test application on a small surface area in order to evaluate the quality of the coating. Varnishes are flammable materials with complex chemical compounds, so work with them is necessary with the observance of safety precautions.

Varnish for stone prevents the formation of fungus on the material, salt spots, increases the resistance of mineral stone bases, blocks the capillaries of porous surfaces. The composition has a high fluidity and adhesion, good astringent and penetrating properties.

It is used to protect walls, floors, streams, various products and structures from natural and artificial stone. Processing of products made of stone, located in the open air, is limited. It is not recommended to apply it in the absence of a lower waterproofing.
