VELA WOOD PRIME UNIVERSAL PU is a high-quality water-based polyurethane-modified acrylic wood primer designed for preparing wooden surfaces before painting and applying decorative coatings. It is suitable for both interior and exterior use, providing a reliable foundation for a high-quality and long-lasting wood finish.

Thanks to modern polyurethane technology, the primer penetrates deeply into the wood, strengthens wood fibers, and improves the adhesion of the subsequent paint layer to the substrate. It reduces wood absorbency, helps block the migration of tannins and other wood extractives, and enhances surface moisture resistance. The flexible and vapor-permeable coating provides high resistance to weathering and temperature fluctuations.

This universal wood primer is suitable for wooden facades, cladding, windows, exterior doors, fences, gazebos, pergolas, garden buildings, wooden walls, and ceilings, as well as plywood, OSB, and MDF boards. VELA WOOD PRIME UNIVERSAL PU is compatible with various water-based and solvent-based topcoat systems, including acrylic, polyurethane, hybrid, alkyd, and alkyd-urethane paints.

Before applying VELA WOOD PRIME UNIVERSAL PU, ensure that the wooden surface is dry, stable, and clean. Remove dust, dirt, grease, wax, resin, mold, wood blue stain, and any loose or damaged parts of the old coating. The wood moisture content must not exceed 18%. Thoroughly clean previously painted surfaces, sand them until a firm, matte finish is achieved, and completely remove any sanding dust.

Mix the product until a homogeneous consistency is obtained and apply it using a brush, roller, airless sprayer, air-assisted (Airmix) sprayer, or pneumatic sprayer. If necessary, dilute with clean water: when applying with a brush or roller, add up to 5% water, and when using an airless sprayer, add up to 3%. The recommended coverage on planed wood is 8–10 m²/l, while on sawn wood it is 5–7 m²/l. Apply at an air and surface temperature between +5 °C and +30 °C and a relative air humidity below 80%.

Do not perform priming during rain, fog, or snow, in direct sunlight on strongly heated surfaces, or if precipitation is likely before the coating has dried.

Hardened material and empty packaging should be disposed of as household waste.
