Surface preparation before treatment

Wood moisture content must not exceed 20%. Perform application at the temperature between  5°C and 25°C, relative humidity between 40% and 75%, and varnish temperature between 18°C and 25°C.
Finish outdoor surfaces so that the varnish surface can dry before the evening dew falls.
Do not perform the application in direct sunlight, at high temperatures and in case of exposure to draughts. Clean the surface from dirt, grease, oils, silicone or wax. Use White-Spirit solvent to wipe new hardwood surfaces (oak, beech).
Dampen rough surfaces, using a spray bottle; let them dry and sand off the fibres of wood raised by dampening. Before finishing previously varnished surfaces, we recommend making a varnish swatch on a small surface patch to check that the materials are compatible.
Previously varnished surfaces do not require preliminary priming; they need to be thoroughly cleaned from old peeling varnish, carefully sanded and cleaned from dust.
For priming new non-painted surfaces, dilute the varnish with White-Spirit in the ratio of 5:1.
Treat the surfaces exposed to the weather impact with the Biostop agent and prime them with diluted varnish.

Application

Before application and in the process of working, stir the varnish thoroughly but carefully (to make sure you do not cause air bubbles to form in it). Stirring ensures that the gloss of the varnish coating will be even when it dries.
Apply 2 coats of varnish on the surface along the grain of the wood or in the direction of the light from the window. 
The number of varnish coats depends on the porosity of the wood and the instrument you use. 
Sand the surface with fine sandpaper (120–150) and remove the dust before applying each following coat on the new surface that has not been previously painted.
Apply finishing varnish on previously varnished surfaces in thin coats without priming. 
Only apply each following varnish coat after the previous coat has fully dried. 
Use tinted varnish for the first coat only. Apply non-tinted varnish as the last coat.
You can use the Balance decorative wood protecting coating (in supplied colours or tinted) as the first coat for tinting. 
To check the tint, we recommend making a varnish swatch on a separate board as the final tint of the coating depends on the species of wood (exotic or unknown wood species can change their colour or get stains), the initial hue and the number of varnish coats.
Hardwood species should be used for surfaces exposed to mechanical impacts or requiring high durability.
Softwood species (spruce, pine, lime tree etc.) are likely to suffer deformation even after varnishing. 
Make sure the working area is well-ventilated, but with no draughts that can cause surface defects. In a dry and hot climate, turn down the ventilation to prevent the paint from drying too fast and avoid lap marks.

Care for the treated surface

Avoid using detergents or vigorously cleaning freshly varnished surfaces because it takes the coating two weeks to reach its peak hardness and durability after the varnish is applied. If necessary, wipe lightly with soft damp cloth during this period. In approximately 2 weeks after varnishing, the dried coating can be cleaned with neutral (рН 6–8) detergents and a soft sponge or cloth. Rinse the surface thoroughly with clean water and dry it after cleaning.
Rinse the surface thoroughly with clean water after cleaning and dry it. .

Tools

Brush, padded varnish applicator, spray gun with 0.009–0.013” nozzle. When applied with a spray gun, the varnish can be diluted with White Spirit in the amount of up to 10% of the varnish volume When applied with an applicator, little of the varnish is absorbed by the wood, which results in its lighter colour. The blade of the applicator must be flexible enough to follow the roughness of the floor and sufficiently sharp for the applicator to act as a knife and smooth down protruding wood fibres. The brush used for varnish application must be wide with well-fastened natural or synthetic bristles.

Tool cleaning

Wash with White-Spirit after completing work.

Store and transport in undamaged containers at the temperature up to +30°C.  Store in a well-ventilated place. Keep cool. Keep container tightly closed.  Keep away from heat, hot surfaces, sparks, open flames and other ignition sources. No smoking.
