Decorative varnish consists of a set of substances that form a thin, almost invisible film on the surface of the coated product. In addition, the compounds are not soluble in water and organic solvents. After complete drying of the decorative varnish, in addition to additional strength, the item receives a pronounced shine.
Depending on the scope of use, varnishes are divided into groups. Since we will talk about decorative coating, then you will get acquainted with the paintwork for wood and stone.
Wood varnish requirements
Decorative varnish for wood emphasizes the texture and beauty of wood, while maintaining the aesthetic appearance of the material. Apply paintwork in the case when it is necessary to give wood or stone special decorative properties and appearance.
A special advantage of wood coated with decorative varnish is protection against decay, the formation of mold and fungi, the appearance of corrosion, as well as good thermal insulation. Color, thickness and lacquer film are of no less importance in maintaining the texture of the tree species.
What are varnishes for wood and how do they differ
Varnishes are distinguished:
- Oil, often used in wood processing and originally produced on the basis of natural resins.
- Based on alkides - glyphthalic and pentaphthalic synthetic resin with the addition of desiccant.
- Alcohol, giving the surface a lasting shine.
- Alkido-urea containing a solution of alkyd and aminoformaldehyde resin.
- Polyester, consisting of a whole chemical set of components.
- Based on acrylic dissolved in organic solvents.
- Polyurethane with extremely high strength characteristics.
- Water-based polyurethane - an innovative material, invented relatively recently.
Features of varnish for stone
Stone, tiled, ceramic surfaces indoors are less exposed to water and moisture than those that are on the street. At the same time, the indoor microclimate of the room no less affects the state of the material.
Wet stone varnishes create an exceptionally strong transparent film layer, emphasizing the texture and color saturation of the surface treated with a decorative coating. In this case, the object externally acquires silkiness.
What varnish is suitable for coating stone surfaces
Acrylic paints and varnishes - ideal. By the type of base, there are aqueous and organic (solvent-based). The former are environmentally friendly, since they do not emit toxic odors into the air and do not evaporate. As for organic acrylic varnish, it is characterized by the best performance, but it is not so safe.
Acrylic decorative varnish is the best option for coating stones.
What properties does the material have
Both organic and water-soluble compounds are characterized by:
- the possibility of use in interior and exterior decoration;
- significant strengthening of the stone surface, whether it be:
- brick;
- paving slabs;
- concrete;
- natural or artificial stone;
- another mineral based coating.
- weather protection;
- hydrophobization of the surface;
- decorative appeal: color saturation, brilliance;
- high degree of adhesion;
- poor sensitivity to the effects of irritants of the biological and chemical groups;
- unexpressed reaction to temperature changes and the effect of UV;
- high resistance to mechanical damage;
- poor susceptibility to abrasion;
- extending the life of stone products.
Decorative varnish for wood and coatings for stone - modern finishing materials that give new properties to the processed surfaces. Such products will last much longer than ordinary, not coated with a protective layer.
