Why us? We help people choose genuinely safer paints and finishes, without the greenwashing. We’re an independent shop, not a paint brand, and we only recommend products we truly believe in, or have tested and tried. For us, this is personal: better indoor air quality matters. Don't just take our word for it, read our Reviews. What is a natural paint?

Info: Osmo WR Base Coat (4001)
Ideal as extra protection for softwood species for the exterior. A clear wood impregnation which serves as a preventive protection against blue stain, rot and insect attack. Penetrates deeply into the wood – prevents swelling and shrinkage and is extremely water repellent with a very low odour during application and is completely odourless when dry.
- Approx. coverage: 5-6m²/L with one coat
- No. of coats: 1
- Application temperature: 5°C
- Drying time: 12hrs.
- Sizes: 0.125L, 0.750L, 2.5L
- 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 neccessary de-nib to smoothen the surface.
- Use biocides safely. Always read the label and product information before use.
- Note: 4005 WR Base Coat Aqua was discontinued in 2016 and superseded with an improved oil-based version 4001 WR Base Coat.
