Osmo is a German-engineered hardwax oil finish system based on natural vegetable oils and waxes that penetrate into the wood rather than forming a plastic film on the surface. Osmo finishes keep the wood looking and feeling like real wood -- not like wood under a layer of varnish. The finish is microporous, allowing the wood to breathe and regulate moisture naturally. Trusted worldwide by professional woodworkers, furniture makers, and flooring specialists. Available at Windsor Plywood locations.

Pro Tips
- Apply Osmo in thin coats -- the most common mistake is applying too much product. Spread a thin layer, wait 15-20 minutes, then buff off any excess with a cloth. The finish should be in the wood, not sitting on the surface.
- Osmo's biggest advantage over polyurethane is repairability. When a section gets scratched or worn, sand that area lightly and reapply Osmo. The repair blends seamlessly with the surrounding finish. This is not possible with polyurethane.
- For live edge tables finished with EcoPoxy river fills, use Osmo Polyx-Oil on the wood portions for a natural, matte contrast against the gloss of the epoxy river. This is a premium finishing combination available entirely at Windsor Plywood.
Frequently Asked Questions
What is the difference between Osmo and polyurethane?
Polyurethane sits on top of the wood as a plastic film. Osmo penetrates into the wood. Polyurethane makes wood look and feel like it is under a coating. Osmo makes wood look and feel like natural wood. Polyurethane cannot be spot-repaired. Osmo can. The trade-off is that Osmo requires more frequent maintenance on high-wear surfaces.
Is Osmo food-safe?
Osmo Top Oil is specifically certified food-safe for countertops, cutting boards, and food-contact surfaces. Confirm the specific food-safe product with your local Windsor Plywood team.
