Osmo UV-Protection Oil Extra Satin 420C 0.75L
Osmo UV-Protection Oil Extra Satin (420C) 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. It delivers a satin sheen while providing robust protection against moisture, dirt, and UV degradation.
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: 0.75L
Also Available: Osmo UV-Protection Oil Extra Satin 420D 2.5L. Browse the full Osmo range.
