Biocide-free wax impregnation - especially for applications in wet rooms!
Clear, microporous wood impregnation based on natural oils and waxes without biocides or preservatives. Due to its high physical wood protection, it is well suited for coating wood that is susceptible to blue stain. Osmo Wood Protector is strongly water-repellent. This low viscosity impregnation should be, if possible, applied to all sides and requires a top coat within one week. For the top coat, Our Osmo wood coatings, for example Osmo Wood Wax Finish, Polyx®-Oil or Wood Wax Finish Clear Extra Thin, are well suited. When dry, finish is safe for humans, animals and plants and is suitable for children’s toys as per EN 71.3 (European norm) and is resistant to saliva and perspiration according to DIN 53160 (German industrial norm).
Osmo Wood Protector is suitable for all interior wood furniture made of wood species susceptible to blue stain (e.g. Pine), window frames and wood in bathrooms, as well as exterior wood, for which an absolutely ecological, biocide-free impregnation is desired, for example playground equipment and sandboxes.

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

Approx. 24-36 hours (normal climatic conditions, 20-23°C/ 50-65% rel. humidity). Ventilate well while drying. Lower temperatures and/or higher air humidity may increase drying times.
Oils enhance the natural tone of wood (permanent wet effect). When using Osmo Wood Protector on large areas under Osmo One Coat
Only HSPlus, glossy spots may appear because of the extremely high content of solids in this stain. Due to the strongly water-repellent effect,
