Osmo Garden Furniture Oil – Clear Exterior Wood Oil

Clear Protection for Wooden Garden Furniture

Exterior wooden furniture is regularly exposed to rain, dirt, sunlight, food, drink and changing temperatures. Osmo Garden Furniture Oil penetrates into the timber and helps replace oils lost through weathering while maintaining a natural-looking surface.

Because the finish remains microporous, moisture vapour can continue to move through the timber. This helps reduce excessive swelling and shrinkage and avoids the cracking and peeling associated with many film-forming exterior coatings.

Suitable Timber Species

Natural oils, resin, extractives and previous treatments can affect absorption and drying. Always complete a representative test before treating the complete item.

New Hardwood Furniture May Need to Weather First

New teak and many tropical hardwoods contain natural oils and extractives that can prevent Garden Furniture Oil from penetrating and drying correctly. Allowing the furniture to weather outside helps reduce these surface ingredients and improves absorption.

How to Apply Osmo Garden Furniture Oil

1. Confirm that the furniture is clean, completely dry and ready to accept oil.
2. Stir the product thoroughly. Do not thin.
3. Apply the first coat exceptionally thinly using an Osmo Flat Brush or lint-free cloth.
4. Work with the wood grain and spread the oil thoroughly.
5. Complete individual slats or components from end to end where possible.
6. Check joints, corners, undersides and end grain for heavy deposits.
7. Redistribute or remove all visible excess.
8. Allow approximately 12 hours’ drying with good ventilation.
9. Once the first coat is fully dry, apply a second equally thin coat.
10. Protect the furniture from rain, dew, dust and handling while drying.
11. Allow the finish to cure fully before prolonged or demanding use.

Applying with a Lint-Free Cloth

1. Place a small quantity of oil onto the cloth rather than pouring it directly onto the furniture.
2. Work it firmly into the timber along the grain.
3. Spread the oil over as much surface as possible.
4. Use a clean section of cloth to remove all wet-looking residue.
5. Take particular care around slats, joints and end grain.

Restoring Greyed Garden Furniture

1. Remove cushions, loose dirt and surface debris.
2. Wet the timber as directed in the Wood Reviver instructions.

• The timber begins to look dry or faded.
• Water no longer beads effectively.
• Frequently touched areas appear lighter.
• The surface becomes rougher or less richly coloured.
• The finish remains intact but protection is visibly reducing.

Important Application Notes

• Use on suitable exterior wooden furniture.
• Apply two exceptionally thin coats to bare timber.
• One thin coat is normally sufficient for maintenance where the existing finish remains sound.
