Overview

Osmo Decking Oil is an oil-based, transparent, satin ideal for use on decking and all exterior wood including garden furniture and privacy screens. The oil is a microporous finish that allows the wood to breathe and reduces swelling and shrinkage and stops your exterior wood from cracking, peeling, flaking, and blistering. It's also water-repellent, extremely weatherproof, dirt-resistant, and UV stable for ultimate protection against the elements. When dry Osmo Decking Oil is completely safe for humans, animals, and plants and will allow you to see the natural beauty of the wood grain.

• Low Odour
• Does not crack, peel or flake
• Very water and dirt resistant
• Natural wood grain remains visible

Preparation

Always ensure the surfaces to be treated is clean, dry, and frost-free.

Bare wood

• Species with a high content of natural wood extractives will need to weather off, usually for 4 weeks minimum. Alternatively clean with to degrease.
• Resinous wood, such as Larch or Douglas Fir needs to weather for at least 6 weeks.
• Pressure impregnated wood and tropical species like Massaranduba, Bangkirai, Garapa, Iroko need to weather off for at least 3 months.
• Cedar requires 3 months to weather off to improve absorbency.

Weathered Wood

• Greyed and weathered wood can be refreshed with .
• Avoid using power washers as this can significantly affect the coverage of Osmo Decking Oils.
• Clean and sand old microporous stains and completely remove old varnishes before application. Sanding to finishing grades of no more than a P120 grit is recommended.
• If additional protection against blue stain, rot, and insect attack is desired ( e.g. softwoods) , pre-treat the wood, if possible on all sides, with Osmo WR Impregnation.

Application

Before applying the product test a small area on the surface to be treated to ensure you are happy with your results.

• Stir product thoroughly.
• Use a stiff brush or lint-free cloth, we recommend using Osmo's Decking Brush (150mm) for quick and easy application.
• Apply thinly and evenly along the wood grain.
• Leave to dry for 12 hours.
• Apply a second coat as above ensuring to apply the product thinly.
• If a less intensive colour is desired, the second coat should be carried out with clear Anti-Slip Decking Oil 430. Generally the more rich and dark the colour chosen, the higher the level of UV protection offered. Avoid applying clear Anti-Slip Decking Oil 430 as a stand-alone finish as this offers limited UV protection.

Note: Always follow the manufacturer's instructions found on the bottle.
