There are a wide variety of paints and varnishes suitable for various surfaces. The main determining factor in the selection is the material to be coated and its properties.
Benefits
Acrylic glossy varnish is used not only to provide decorative properties, but also to increase the period of use of the product and protect the surface from adverse effects. He gained his popularity due to many advantages, among which are the following:
- quick drying;
- creating a reliable and durable coating on any surface;
- does not change the natural texture and shade of the material;
- high elasticity and strength;
- environmental friendliness.
Special compounds
Universal Acrylic Gloss Varnish Kudo has a high level of resistance to weathering and excellent adhesion. Suitable for creating a decorative sheen on plastic, wooden and metal products, regardless of the presence of a paint layer. It can be used both for internal and external work. At the same time it protects the surface from abrasion and mechanical stress, hides coating defects. Like any acrylic compound, Kudo varnish is characterized by excellent performance. It is water resistant, transparent in structure and odorless.
Glossy acrylic varnish for artwork is ideally suited for processing colored surfaces to create a shiny and smooth top coat that is resistant to dirt, moisture and wear. This is not limited to its application, it provides the following tasks:
- fixing details of work performed using chalk or coal;
- adding to gouache paint to obtain wear-resistant characteristics and increase adhesion;
- increase the durability of the coloring compounds and giving brightness;
- acts as a bonding base for the preparation of paints at home.
Acrylic varnish, the price of which starts at 200 rubles, is used not only to protect the surface, but also to obtain decorative effects. It is optimally suitable for wood, as its composition penetrates into the pores and forms a dense film. It also has antiseptic properties, due to which it prevents the appearance of mold and fungus.
What you need to know
Before applying the composition, it must be thoroughly shaken. When applying two or more layers, when necessary, grinding can be performed. It is worth remembering that during the process of work the air temperature should be at least +5 degrees. To create a high-quality surface, the acrylic gloss varnish should not be exposed to ultraviolet radiation and draft during drying. Some components in the composition during long-term storage may settle to the bottom in the form of a loose residue, so the mixture is thoroughly mixed before use. So, after the sediment is distributed over the contents, the material acquires a homogeneous structure.
Composition
Glossy acrylic varnish for artwork is made on the basis of polyacrylates, or substances formed after the polymerization of acrylic acid. The compositions are classified depending on the type of film-forming component:
- Varnish with thermoactive oligomers (styrenes, acrylates and other substances). It creates an insoluble surface, film formation occurs in 30-50 minutes when exposed to high temperatures. Plasticizers are possible, for the dissolution of which hydrocarbons, ketones and acetates are used.
- Composition based on thermoplastic and high molecular weight acrylates. It forms a reversible surface, the film is created within an hour at room temperature in the process of volatilization of soluble components.
Application features
Acrylic glossy varnish is applied most often using pneumatic spraying; the electrodeposition method is used for water-borne formulations.
To get a uniform high-quality coating on wooden surfaces and reduce consumption, pre-treatment is carried out with a special primer or tinted impregnation.
Creating a mirror surface is possible after wet grinding. That is, the base is polished after wetting and drying, only after that a primer is applied. Also, this effect can be obtained by grinding all layers of varnish, with the exception of the latter.
Acrylic glossy varnish is suitable for updating the painted surface, in case of thinning of the previous layer. To do this, the surface is treated with sandpaper and soap solution, then the composition is distributed, before using it, it is also possible to apply acrylic paints. It is worth noting that the varnish is diluted only in pure water, without the addition of drying oil and solvents.
