The grain of a tree is a unique fingerprint of nature: The even and beautiful surfaces of Osmo Wood Filler preserve this individual character. Unlike most woodfillers, it can easily be sanded at any time after drying, and it's fast drying - within approx. 30 minutes. Non-flammable and non-toxic, heat and freeze-proof, will not crack, shrink, sink or fall out.


  • Quick drying
  • Can be retreated with all Osmo wood finishes when dry
  • Fills small and large cracks
  • Does not shrink or fall out (suitable for ceilings)
  • Can easily be sanded at any time after drying


1. Using a plastic or high-quality stainless steel putty knife, apply OSMO WOODFILLER to the floor directly out of the tub prior to the last sanding. (NOTE: If filler turns black, the putty knife is not highcontent stainless steel; however, the black will sand off.)

2. If the hole is greater than 6mm, fill by layering Osmo Wood Filler in 6mm increments.

3. Let Osmo Wood Filler dry thoroughly. It is properly dry if it sands to the consistency of talcum powder.

4. Sand and remove all dust and debris.
