Osmo UV-Protection Oil Extra Satin 420D 2.5L
Osmo UV-Protection Oil Extra Satin (420D) is a premium natural oil-wax finish for exterior timber with extra-strength UV protection, designed to significantly slow the natural greying and colour change of wood exposed to sunlight. The 2.5L size is the trade buy for larger exterior projects.
The Extra formulation offers enhanced UV filter performance compared to standard UV-Protection Oil, making it particularly suitable for south-facing elevations, exposed decking, and timber in high-UV environments. Based on natural oils and waxes, it penetrates the wood rather than forming a surface film, so it won't crack, peel, or flake.
- Finish: Satin
- UV protection: Extra-strength UV filters for maximum colour retention
- Coverage: Approx. 8–12 m² per litre (two coats)
- Application: Brush or lint-free cloth, applied thinly along the grain
- Coats required: 2 coats recommended
- Suitable for: Exterior cladding, garden furniture, fences, decking, and joinery in high-UV environments
- Properties: Microporous, water-repellent, extra UV-resistant, non-cracking, non-peeling
- Drying time: Approx. 12 hours between coats
- Size: 2.5L
Also Available: Osmo UV-Protection Oil Extra Satin 420C 0.75L. Browse the full Osmo range.
