Preparing a floor surface to be finished with OSMO Polyx Oil

Having the floor sanded correctly is essential. To achieve the best result, we recommend using a professional floor sander. Because Polyx Oil is clear, any sanding marks left in the timber will become highly visible once the finish is applied. The final finish will depend upon your requirements - whether you want a glass "ballroom" finish or a more rustic look. 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.
