Instructions

Step 1

In addition to the composition, parquet varnishes are classified according to the degree of wear resistance and the degree of gloss. According to the degree of gloss, matte (reflect 0-30% of light), semi-matt (30-70%) and glossy varnishes (70-100%) are distinguished. Dullness is achieved due to the presence of a passive filler in the composition. However, remember that the filler settles to the bottom, so the varnish must be thoroughly mixed before use. According to the degree of wear resistance, varnishes with increased, medium and low abrasion resistance are distinguished. The former should be used in non-residential premises where a large number of people walk, often in street shoes. The latter are suitable for home, where they wear slippers.

Step 2

Polyurethane varnishes There are one- and two-component polyurethane varnishes (PUR and DD). These varnishes may or may not contain aromatic compounds. Polyurethane varnishes can be produced on a variety of bases: acrylic, urethane, or solvent based. When dry, the solvent first evaporates and then chemically hardens. Pros: heat and light resistance, excellent adhesive properties, high elasticity. Good for high traffic areas. After drying, they are resistant to household chemicals and the ingress of liquids to the surface. These varnishes are not demanding on the temperature and humidity in the room. Cons: gluing parquet planks. Sensitive to moisture during application and drying: moisture will cause the varnish to foam.

Step 3

Water-borne varnishes Water-borne varnishes are generally a dispersion of film-forming substances in water. Such varnish is applied exclusively with a roller, and not with a brush or swab. The room temperature should be within 15-22 ° С, air humidity - 50%. Before applying the varnish, it is advisable to cover the parquet with a primer. Pros: water-soluble varnishes are almost odorless compared to oil, polyurethane varnishes. Such varnishes are non-flammable, they are distinguished by good adhesion and transfer of the texture and texture of the parquet. Cons: very low wear resistance. Suitable for low-traffic living spaces. When flowing into cracks, the varnish glues the sides of the parquet planks. Not very well suited for parquet from "nervous" species - beech, hornbeam, pine. Under no circumstances should the varnish freeze.

Step 4

Varnishes based on artificial oil resins This group includes adkyd and urethane alkyd varnishes. These varnishes are made on the basis of wood or linseed oil and penetrate deep enough into the wood. According to the degree of shine, there are matte, silky-matte, semi-matte, glossy. They are applied in a thin layer of no more than 120 g / sq.m. Pros: they do not glue the sides of the planks. No need for prior application of a primer. Not slippery. Cons: poorly dry at high or low indoor temperatures, toxic, dry for a long time (8 hours or more).

Step 5

Acid-curing varnishes These varnishes consist of two components - the varnish itself and the hardener, which is added to the varnish before starting work. These varnishes are used in rooms with high demands on the durability of the coating. Pros: high adhesion, not demanding on humidity and temperature in the room, as well as on tools. No primer required. Cons: they strongly glue the strips. They have a strong odor.
