Application Overview

Surface Preparation

Ensure the wood surface is clean, dry, and frost-free (maximum 18% moisture content).
Stir the Osmo Oil Stain thoroughly before use; do not thin.
Remove old microporous stains, paints, or lacquers completely through sanding.
Fill cracks, larger joints, or holes with Osmo Wood Filler as needed.
Sand surfaces carefully:
- Use P120-150 grit for flooring.
- Use P220-240 grit for furniture.
Remove sanding dust with a broom or vacuum cleaner.
Conduct a trial application on a small area to ensure desired results, as the wood's natural characteristics may influence the finish.

Methods of Application

Transparent Color:

Apply a very thin, even coat to the clean and dry wood along the grain using one of the following tools:
- Osmo Double Blade Scraper.
- Osmo Microfibre Roller.
- Osmo Floor Brush 150 mm.
Massage the stain into the wood using a white pad.
Allow to dry for approximately 12 hours with good ventilation.

Intensive Color:

For a stronger color intensity, repeat the process with a second thin, even coat.
Spread evenly and ensure uniform application.

Tips:

For transparent finishes, remove any brushstrokes within 30 minutes using an unused Microfibre Roller.
For furniture and smaller areas, apply the stain with a lint-free cloth.
After thoroughly drying, apply a topcoat of clear Osmo Polyx®-Oil for optimal protection.

FAQ

Small scratches or marks on your floor can be repaired using the Osmo Repair Set, which includes a heating gun and wax sticks. Simply heat the wax stick, apply it to the scratch, and smooth it with a spatula. Choose a wax stick color that matches your wood for the best results.

For worktops treated with Osmo TopOil, clean regularly with soapy water and a cloth. Do not use abrasive powders or scouring pads. For deeper cleaning and maintenance, occasionally use Osmo Liquid Wax Cleaner or Osmo Maintenance Oil to keep surfaces looking their best.

To restore weathered and greyed exterior wood, use Osmo Wood Reviver Power Gel to remove the greyed fibers and bring back the wood's natural color. Afterward, apply a suitable treatment from Osmo's exterior product range for lasting protection.

Seal the end grain by applying a small amount of Osmo End Grain Wax Sealer with a cloth. Allow it to dry thoroughly to ensure a durable seal against moisture.

Interior wood: Re-application is typically needed every 3-5 years, depending on the level of use and maintenance.

Exterior wood: Re-application varies from 3-10 years, influenced by exposure to sunlight and weather. Coastal or south-facing woods may require yearly maintenance.
