Osmo 4001 WR Basecoat is ideal as an extra protection layer for softwood species used on external applications. A clear wood impregnation serves as a preventative protection against blue stain, rot or insect attack. The WR Basecoat penetrates deeply into the wood, preventing any swelling or shrinkage and is extremely water repellent.
Advantages of the Osmo 4001:
- Only 1 Coat Needed
- Reduces wood swelling or shrinkage
