Notes & Tips


  • WR Base Coat is not a wood finish and is a base coat only. A finishing product from the Osmo range is required within three months
  • If possible, although not essential; apply to all sides of the wood to give the strongest protection. Wipe excess from edges with a dry cloth before leaving to dry
  • Some applications may raise the wood’s grain, if necessary de-nib to smoothen the surface
  • Use biocides safely. Always read the label and product information before use
  • Supercedes the previous "WR Base Coat Aqua" with an improved oil-based version
  • 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

questions Anna on 2023-10-24 21:39:39
Question: 

Hi, How many coats are required? Thank you, Anna

Answer from Rawlins’ Technical Team:

Assuming the timber is clean, dry, frost-free and lightly abraded prior to application, 2-3 coats is recommended by either brush or roller, spreading out thinly and evenly along the wood texture to achieve the best results.

Once the timber is completely dried, we'd recommend a finish coat from the Osmo exterior finish range such as Osmo UV Protection Oil, Osmo Natural Oil Wood Stain or Osmo Country Shades, depending on the desired outcome.
