How do I fill gaps and cracks in the wood?
Osmo Woodfiller can be used to fill gaps, splits and cracks in the wood. If you will be staining the wood afterward, we recommend to use 73001 Natural since this can be coloured to match the floor colour – trial application required!
Alternatively, choose from a selection of Woodfiller colours to try to match the existing wood’s colour.
For larger areas, a more suitable and accurate alternative to matching the colour is Osmo Wood Putty mixed with the sanding dust to maintain the wood’s natural colour.
