NOTE
Osmo Garden Furniture Oil is clear; therefore it offers no UV protection (greying). Due to their surface properties, ribbed or rough saw wood surfaces absorb more product. Many wood species contain water-soluble coloured extractives which may leach out naturally when weathered.
SURFACE PREPARATION
Wood species with a high content of natural wood extractives need to weather off (min. 4 weeks) before the initial treatment or be cleaned with Osmo Brush Cleaner and Thinner (degreaser). Resinous wood, such as Larch or Douglas Fir, needs to weather off for at least 6 weeks. Pressure-impregnated wood, Massaranduba,Bangkirai or Garapa need to weather off for at least 3 months. De-grey any already greyed wood with Osmo Wood Reviver Power-Gel before applying Osmo Garden Furniture Oil. Wood surface must be clean, dry and frost-free (moisture content max. 20%). Osmo Garden Furniture Oil is ready to use. Do not thin. Stir well before use. Thoroughly clean or lightly sand old microporous stains or completely remove old varnishes before application. Always wear a dust mask while sanding. If possible, please apply the first coat to all sides before installation. If additional protection against blue stain, rot and insect attack is desired, pre-treat the wood, if possible on all sides, with Osmo WR Impregnation.
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.
