Osmo Door Oil Satin is a clear wood finish that uniquely combines the advantages of natural oils and waxes in one product. Osmo Door-Oil is resistant to dirt, water and abrasion and smooths the surface. Creating a microporous surface, this oil coating will not crack, peel, flake or blister making it ideal for the protection of solid and some selected veneered wood interior doors. Preparation and Application of Osmo Door Oil For best results, ensure your wood surface is clean, dry, and frost-free (moisture content max. 18%). Osmo Door-Oil is ready to use; no thinning is required. Simply shake well before use and thoroughly clean old microporous stains, removing old paints, varnishes, and lacquers. For quick and easy application, use an Osmo Flat Brush or Osmo Microfibre Roller, applying thinly and evenly to the clean and dry wood along the grain, spreading well. Ensure good ventilation.
