How should the floor be sanded and prepared for application of OSMO Polyx-Oil?
Proper preparation of the floor is one of the most important factors in a successful OSMO Polyx-Oil application. The final sanding should use no finer than 120-grit sandpaper. Be extra-careful that no marks or gouges are left in the surface of the wood, as the penetrating finish will accentuate these marks. Pay particular attention to the transitions from the drum sander to the edger. Use a vacuum and a dry cloth, alternately, to remove any sawdust or sandpaper grit. Leftover dust or debris will get caught in the finish, leaving you with a rougher texture.
