Beger Polyurethane 2K Supreme

Step 1 Surface preparation: - If the wood has been painted before and the film is peeling, or it is old wood that has never been painted, first sand it back to the bare wood, then clean the surface so it is free of grease, dust, oil and foreign matter. - For new wood, sand off excess wood fibers and clean the surface so it is free of grease, dust, oil and foreign matter. - If the wood has resin, wipe off the resin with Thinner M-77. - If the wood has cracks, holes or nail heads, fill them first with Beger Wood Filler, leave for 30 minutes, then sand and clean

Step 2 Primer: - To protect wood from mould, termites, wood borers and wood-boring insects, we recommend 1 coat of clear BegerDrite (water-based or oil-based) brush-on, applied to all 6 sides. - For resinous wood such as Daeng, Takhian or Lumphor, apply 1 coat of Beger B-2000 wood resin-blocking primer to improve adhesion. - For non-resinous wood, apply 2 coats of Beger Sanding Sealer B-5000/599 (2-component) or Beger Sanding Sealer B-2400. Cautions: - Never prime with shellac or lacquer, as this will cause peeling. - Do not use pigment powder or shellac to stain the wood, as the powder blocks adhesion between Beger Polyurethane 2K Supreme and the wood

Step 3 Topcoat. Gloss film: apply 3-4 coats of Beger Polyurethane 2K Supreme P-910 (gloss), mixing ratio by volume Part A : Part B = 1:1, ready to use. It can be applied without thinner, but for large areas you can add 20% Beger Thinner M-50 by volume. Semi-gloss film (40% matte): apply 2-3 coats of Beger Polyurethane 2K Supreme P-910 (gloss), mixing ratio by volume Part A : Part B = 1:1, then 1-2 coats of Beger Polyurethane 2K Supreme P-915 (semi-gloss), stirring Part A : Part B = 1:1, ready to use. It can be applied without thinner; for large areas you can add 20% Beger Thinner M-50 or M-59 by volume. Matte film (70% matte): apply 2-3 coats of Beger Polyurethane 2K Supreme P-910 (gloss), mixing ratio by volume Part A : Part B = 1:1, then 1-2 coats of Beger Polyurethane 2K Supreme P-911 (matte), mixing ratio by volume Part A : Part B = 1:1, ready to use. It can be applied without thinner; for large areas you can add 20% Thinner M-50 or M-59 by volume. Notes: - Stir 2-component polyurethane well before and regularly during application so the mixture stays uniform. Beger Polyurethane 2K Supreme can be applied without thinner; if you want to thin it, use Beger Thinner M-50 or M-59. Matte polyurethane (of any brand) may show brush marks, depending on the surface condition, mixing, application method and how light falls on the area. - To adjust the wood color, or if the wood color is uneven or varies, especially parquet floors made from several types of wood, apply at least 2 coats of Beger Polyurethane B-5000 Color, mixing A and B at 1:1 without thinner. For spraying, thin with only 0-10% Beger Thinner M-50 by volume. Let each coat dry for 2-3 hours before the next
