Osmo UV Wood Protection Exterior Oil 420 Satin Clear 750ml

All exterior woods grey into a patina colour over time, but UV-Protection Oil has been developed to maintain the wood's natural colour and slow the greying process by (UV factor) 12 times in comparison to untreated wood. Ideal for windows, doors, cladding, fencing and other vertically structured joinery (not recommended on flat surfaces such as decking). Natural oil-based and microporous finish does not crack, flake, peel or blister. Water and dirt resistant, moisture regulating and reduces wood swelling and shrinkage.
