Opaque Gloss Wood Stain

Surface Preparation

Wood surface must be clean, dry and frost-free (moisture content max. 20%).

Osmo Opaque Gloss Wood Stain is ready to use. Do not thin. Stir well.

Clean old microporous stains thoroughly. Old paints and lacquers must be completely removed. As a general rule, wear a dust mask during sanding works.

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 insects is desired, pre-treat the wood if possible on all sides with Osmo WR Base Coat.

Method of Application

With Osmo Flat Brush or Microfibre Roller, apply thinly and evenly to the clean and dry wood along the wood grain and spread well.

Allow to dry for approx. 10-12 hours under good ventilation.

After drying, apply a second coat – also thinly.

For renovation works, one coat applied to the clean and dry surface is usually sufficient.

Note

When used in dark indoor areas, the coating has due to its high oil content a slight yellowing effect.

Using power washers will severely decrease the coverage of the finish and general or multi-purpose cleaners will increase the frequency of maintenance and recoating.

Care

Regular Cleaning: Damp cleaning with Osmo Spray-Cleaner.

Occasional Maintenance: If necessary, intensive cleaning and refreshing using Osmo Wood Reviver Power Gel or Osmo Gard Clean.

Recoating: Simply re-apply one coat onto the clean and dry surface when signs of wear become visible.
