Preparing a floor surface to be finished with OSMO Polyx Oil
Having the floor sanded correctly is essential. For best results, we recommend using a professional floorsander. The final finish depends upon the quality of the sanding - whether you require a glass "ballroom" finish or a more rustic look. Because Polyx Oil is clear, and sanding marks left in the timber will become highly visible once the finish is applied. The following is a preparation guide:
For newly laid timber floors which have not been factory finished, the sanding should result in a clean even surface before coating with oil.
Floors which are old, worn or grey should be lightly sanded to restore the timber to it's original colour. Any deep grooves or other scratches should be removed.
Floors which have previously been coated with a varnish, polyurethane, stain or paint should have the coating removed, and the timber sanded back to it's original colour.
