Osmo UV Protection Oils are clear, UV rated oils for new timber joinery, pergolas, trellis, timber garden furniture and planter boxes etc. They are not suitable for timber decking.

The finishes are UV Protection Oil 410 and UV Protection Oil - Extra 420.

The 410 has a low satin sheen, and is biocide free, which means it can be used internally on timbers such as window frames, french doors etc. It can also be used outdoors on items such as timber garden furniture, where food may be present.

The 420 has a higher satin finish, and contains biocides. These "Extra" ingredients help fight mould and fungal attack. The 420 should only be used on external timber surfaces where food will not be present. The UV resistance is the same for the 410 and 420.

UV Protection Oils are not suitable for use on horizontal "walk on" surfaces such as decks, as the finish can become quite slippery when wet.

On a 2 coat application, the UV Protection Oils block the greying process of the timber by a UV protection factor of 12, when compared with untreated timber. This is a similar principle to the SPF system of sunscreens we use on ourselves.

In New Zealand, due to the high UV light we have, the clear UV Protection Oils have a lifespan of 4 - 6 months in fully exposed weather conditions, and 12-18 months in areas that are totally weather protected. For longer protection, we recommend using one of the tinted UV Oils, which are available in 6 colour tones. Please click here for further details.

Osmo UV Protection Oils are water and dirt resistant, and are moisture regulating - reducing swelling and shrinkage of the timber.

Easy to apply and maintain, the oil highlights the natural tones of the timber by giving it a "wet look".
