SURFACE PREPARATION
Bare 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 to improve absorbency. Pressure impregnated wood and tropical species like Massaranduba, Bangkirai, Garapa, Iroko need to weather off for at least 3 months. Cedar requires a 3 month weathering period to improve absorbency.
Greyed and weathered wood can be refreshed with Osmo Wood Reviver Power-Gel before applying clear Osmo Teak-Oil Spray 008. Avoid using jet / power washers to clean the surface as they can significantly affect the coverage of Osmo Teak-Oil Spray 008. Wood surface must be clean, dry and frost-free (moisture content max. 20%).
Osmo Teak-Oil Spray 008 is ready to use. Shake spray can well and carry out trial spray.
Thoroughly clean or lightly sand old microporous stains or completely remove old varnishes before application. If any sanding works are carried out some fresh wood species must be weathered as directed above to improve absorbency once more. Sanding to finishing grades of no more than a P120 grit are recommended. Always wear a dust mask when sanding.
If possible, and if the wood is absorbent please apply the first coat to all sides before installation.
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.
If additional protection against blue stain, rot and insect attack is desired ( eg soft woods), pre-treat the wood, if possible on all sides, with Osmo WR Impregnation.
METHOD OF APPLICATION
Spraying distance approx. 25 cm. Afterwards rub in with a brush.
While applying, cover and protect surrounding areas and parts that should not be treated against the spray mist. Wipe away any excess with a cloth.
Allow to dry for approx. 12 hours under good ventilation and apply a second coat.
When renovating, one coat applied is usually sufficient to the clean and dry surface.
Clean spray nozzle after use.
