Osmo Wood Protector is a clear wood primer and preservative. It will help to control blue stain in timbers such as Pine, Spruce and Douglas Fir (Oregon) which are being used in areas where steam and/or high humidity may be present. Normally it is a one coat primer followed by 2 top coats of Polyx Oil.
No Osmo product should be used on any timber which will receive regular quantities of water - such as the inside walls and floors of shower cubicles.
