SURFACE PREPARATION
Wood surface must be clean, dry and frost-free (moisture content max. 18%).
Osmo TopOil 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 Osmo Wood Filler).
Sand wood surfaces carefully. Begin with coarse sandpaper then progress to finer grades– final sanding work for furniture P150-240 (depending on wood species ). For kitchen work tops using absorbent hardwoods like Oak or Beech, final sanding grade P120. For very absorbent woods like Pine, sand to a maximum of P150.
For dark and extractive-rich woods (e.g. Iroko, Teak, Mahogany, Sapele, Wenge, Merbau, Jatoba, Cedar etc.), we recommend using Osmo Wood Wax Finish Clear Extra Thin. A trial application is recommended.
Before oiling the surface, remove sanding dust with a soft brush or vacuum cleaner.
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.
