Topic tags/keywords: osmo hard wax oil

I have a monkey pod wood coffee table that I’m refinishing for a relative. It’s essentially a diagonal slice out of a log with three legs. I wanted to try Osmo Polyx-Oil because it seemed easy and they wanted a more natural finish. The edges and legs turned out great. The top, however, is all end grain and this finish seems to be a great scratch accentuator. It’s especially hard to get the softer area around the pith smooth enough. I’ll think I have it looking good but, as the finish dries, the scratches show up. The other problem is that, even after a few days drying, the moisture from my hand will leave a mark that won’t go away.

I’m ready to try something else. Will polyurethane help my scratch problem? How do you think poly will get along with this hard wax oil. Do I need to get rid of all traces of it?

Thanks

Nothing is going to stick to OSMO Polyx-Oil, so sanding is your best course. Since it’s end grain, that might be difficult to achieve.

It is a high-solids product, so more coats may help with the scratches if they aren’t too deep. Keep the coats thin and don’t apply more often than every 12 hours.

Thanks Rich. This wood is pretty porous so I’m not very confident about getting it all off. It sounds like I might need to stick with the Osmo. Any insight on the moisture issue? If it can be used on floors it seems like it should handle water better than what I’m seeing. Maybe it just needs more time to cure?

It’ll cure hard and waterproof if given the chance. That’s why I suggested many thin coats with plenty of time in between. I have no experience applying it to end grain though, and the depth of penetration could be an issue in how long it takes to cure.

With any reactive finish, OSMO included, if it’s applied too thick too fast, it can seal off the earlier coats and cause them to take very long to cure.
