Wood surface must be clean, dry and frost-free (moisture content max. 18%). Osmo Wood Protector is ready to use. Do not thin. Stir well before use. Clean old microporous stains thoroughly. Old paints and lacquers must be completely removed. As a general rule, wear a dust mask during sanding works. Fill small cracks, larger joints or holes in wood (with wood filler). The finished surface is influenced by several factors, including the condition of the wood. Therefore, a trial application is always required, especially for unfamiliar surfaces. Osmo Wood Protector is compatible with all conventional types of glue and putty (except for products containing silicon).

Apply one time to the clean and dry wood with a flat brush, microfibre roller or by dipping. Coat the clean, dry and frost-free wood generously – if possible, on all sides. Dipping process: approx. 2 minutes dipping time. Ventilate well. Top coat should be carried out within one week.

Approx. 24 hours when brushed and approx. 36 hours when dipped (normal climatic conditions, 23 °C/50 % rel. humidity). Lower temperatures and/or higher air humidity can increase the drying time. Ventilate well while drying.

1 litre covers approx. 6-8.4 m² with one coat. Coverage depends significantly on the condition of the wood. All information refers to smooth and planed/ sanded surfaces. Other surfaces may lead to differences in coverage.

Oils enhance the natural tone of wood (permanent wet effect). Osmo Wood Protector is not to be used alone. Within one week, a top coat (with an oil-based Osmo wood finish) should be carried out. Due to the strongly water-repellent effect, do not coat with water-soluble products (e.g. Interior Wax).


  • Ideal base coat for Osmo Polyx®-Oils for use in bathrooms, kitchens and even swimming pool environments and saunas!
  • Wood Protector is a primer only and requires a finishing product such as  Osmo Polyx®-Oil for flooring, furniture and joinery in bathrooms or kitchens.
  • First application of Wood Protector must be applied onto untreated or evenly sanded surfaces.
  • Wood Protector is clear and therefore will darken the natural character of the wood, please test a small area prior to application.
  • If possible, although not essential; apply to all sides of the wood to give the strongest protection. Wipe excess from edges with a dry cloth before leaving to dry.
