How to properly apply Polifarb (Lacrysil) 7-in-1 acrylic primer-enamel — a universal 7-in-1 coating for wood and metal (including rusty surfaces).

This is a ready-to-use water-based acrylic paint-primer that replaces several steps at once: priming, rust converter, anti-corrosion protection, antiseptic, enamel, and topcoat.

Surface Preparation (very important step!)

• The surface must be dry, clean, free of dust, grease, oil, and peeling old paint.

• Wood: remove resin (with solvent or alcohol), sand (especially glossy or old coatings), remove dust.

• Metal: remove loose rust with a wire brush, degrease (white spirit, acetone, or alcohol). Dense rust can be left in place — the primer-enamel will convert it.

• Old coatings (alkyd, oil-based, nitro): scuff with sandpaper, degrease, test adhesion with a trial application.

• OSB, chipboard, plywood, MDF: it is recommended to prime first or perform a test application.

• Do not apply to wet, heavily greasy, bituminous, plastic, or rubber surfaces (or perform a test).

Application — step by step

1. Thoroughly mix the primer-enamel in the can (using a drill with mixing attachment or by hand until completely uniform).

2. Do not dilute with water (the product is ready to use).

3. Apply with a brush, short-pile roller, or spray gun (air / airless).

4. Number of coats:

   • clean / new surfaces → 1–2 coats

   • rusty surfaces → always 2 coats

5. Apply the first coat evenly, without missing spots.

6. Apply the second coat after the “touch-dry” stage or after the recommended recoat time.

Drying time (at +20 °C and ~60% humidity)

• Touch-dry → 1–2 hours

• Recoat time → 2–4 hours

• Full dry → 24 hours

• Maximum hardness and durability → after 7 days

Consumption

120–180 g/m² per coat (depends on absorbency and surface roughness).
1 kg typically covers ≈ 6–8 m² in one coat.

Application conditions

• Air and surface temperature: +8…+30 °C

• Air humidity: not higher than 80%

• Do not apply in direct sunlight, on hot surfaces, during rain, or if rain is expected within the next 4–6 hours.

• Protect the fresh coating from dust and precipitation for at least 4–6 hours after application.

After work

• Clean tools immediately with warm soapy water (while the paint is still wet).

• Dried paint must be removed mechanically or with solvents.

Useful tips

• Always apply 2 coats on rust — the first converts it, the second provides reliable protection.

• Light colors (white, gray) usually require 2 coats for good coverage.

• Once fully cured, the coating can be washed with a damp cloth and neutral detergents.

• Suitable for interior and exterior use: fences, gates, doors, windows, gazebos, furniture, radiators, agricultural machinery, garages, greenhouses, etc.

• Service temperature of the cured coating: from -50 to +100 °C.

If the surface is very porous or heavily rusted — do a test patch first. Happy painting!
