Type: primer water - dispersed wood available in two grades: primer HP - AK - 057 and the primer VD - AK - 057 "O", which represents a suspension of pigments and fillers in aqueous acrylic dispersion with the introduction of various functional additives.
Scope: primer designed for priming and leveling the absorbency of the wood surfaces prior to application of waterborne paints for wood production "Lakokraska".
Primer WD - AK - 057 is intended for priming wooden surfaces by air, airless spray, brush or roller.
Primer WD - AK - 057 "O" is intended for priming of wooden surfaces by immersion.

Advantages : primer porous reinforcing wooden surface, prevent swelling of wood fibers and improve the appearance of painted surfaces. Primers contribute to the adhesion of the subsequent paint layer and reduce its consumption. The primer coating is easily polished, and formed in the grinding dust does not clog sandpaper.
Surface preparation: The surface must be dry (moisture content of the wood must be 8 - 14% ), free of oil, dust, waxes and other impurities. Before applying the primer sanded wooden surface along wood grain sandpaper grit № 4 and dedusted. Surface defects zashpatlevyvayut and sanded.
Priming: mixed thoroughly before application of the primer and allowed to stand for 20 minutes to remove air bubbles.
Priming products prepared with primer VD - AK - 057 is carried out by pneumatic, airless spray, brush or roller along the wood fibers (in the direction of the pile) with the initial viscosity. If necessary, at the request of the consumer, the primer may be diluted with water (not more than 10% water by weight).
The user independently makes the selection of a viscosity depending on the operating conditions (the ambient temperature in the room, the diameter of the nozzle spray gun, compressed air, etc. operating pressure. )
Priming prepared products Primer WD - AK - 057 "On" is carried out with the original viscosity by dipping. When manually dipping, surface active substances saturation desired, the items must be rotated in the container twice.
Drying primed products at (20 ± 2) ° C and a relative humidity of 65% - at least 2 hours prior to application of paint - primed surface is maintained at a temperature.
(20 ± 2) ° C for at least 2 hours.
Primed product may be dried at a temperature of (35 ± 5) ° C for 1 - 2 hours (depending on the process parameters of drying chambers enterprises) primed products delayed for at least 0.5 hours at a temperature of (20 ± 2) ° C. Dry the primer layer before applying the paint sanded sandpaper № 4 (avoiding proshlifovki coating to wood) and purified from dust.
Flow primers for single - layer coating - 170 - 350 g / m² excluding absorbency, surface roughness, its preparation, and the method of application and other factors determined by the test staining.
At the end of the container, tools, stains wash with soap and water before drying primers.
It is not allowed to mix with other primer primers and solvents of any kind. Hardened remnants of primers and empty plastic containers to dispose of as household waste.
Storage : Primers stored in closed warehouses at ambient temperature from + 5 to + 35 ° C. Keep away from direct sunlight. In the winter time the primer is transported in insulated truck.
Precautions: persons related to the paint work must be provided with personal protective equipment (overalls, safety glasses, rubber gloves). Accidental contact with the eyes, mucous membranes and the skin rinsed with water.
The dried coating does not have toxic effects on the human body
