Osmo WR Base Coat is not to be used alone, instead it is a clear impregnation to protect wood against rot, blue stain and insect attack.
Compatible with all common types of glue and putty (except silicone products). We recommend galvanized, anti-corrosive fasteners.
To guarantee full protection (against UV rays) and the long-lasting beauty of wood, a top coat (e.g. with One Coat Only HSPlus, Natural Oil Woodstain, Country Colour, Opaque White Gloss or UV-Protection-Oil) is required after the impregnation has completely dried.
If the coloured surface should have an external surface protection (film protection), we recommend for non-biocidal wood finishes (One Coat Only HSPlus and Country Colour) a top coat with UV-Protection-Oil Extra.*
*Do not coat white finished surfaces with UV-Protection-Oil Extra.
Using power washers will severely decrease the coverage of the finish and general or multi-purpose cleaners will increase the frequency of maintenance and recoating.
