Give your exterior wood a summer coat

The dry, cool weather we are experiencing at the moment provides perfect conditions for catching up with all those exterior wood preserving projects, shelved throughout the winter months.

Osmo UV Protection Oil Extra 420

Osmo UV Protection Oil Extra 420 is a clear, satin-matt finish, ideal for all vertical exterior woods such as doors, windows and window sills, carports, timber cladding, balconies, screens and fences, pergolas, garden houses and furniture. Its unique composition results in a clear finish which provides UV protection without pigmentation (staining). As a stand alone finish, with two coats, it prolongs the greying process on vertical surfaces by UV protection factor 12 in comparison to untreated wood.

The finish contains active ingredients which protect it from mould, algae and fungal attack. It is easy to renew (no sanding or primer necessary), and easy to apply - it will not dry during application. It can also be used as a final finish after staining, which prolongs the renovation life even further. It is fully compatible with Osmo's range of exterior wood stains, if a tinted colour is preferred.

Osmo Natural Oil Woodstain (available in oak and walnut)

All Osmo products are microporous and, therefore, do not peel, flake or blister. To view our full range of Osmo exterior wood finishes click here >>
