Osmo Woodfiller can be used to fill gaps, splits and cracks in the wood.
If staining the wood, we recommend to use the ‘73001 Natural’ as this can be coloured to match the appearance.
Otherwise, choose one of the other colours from the Woodfiller range to try and match the existing wood’s colour.
Alternatively, we recommend using Osmo Wood Putty which is to be mixed with the sanding dust when sanding the wood. This will achieve an exact match for the wood’s natural colour.
