Application

For Spot Patching:

If staining, use Osmo Woodfiller Natural/Clear. Otherwise match the colour to the wood. 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 high content stainless steel; however, the black will sand off.) Filling: If hole is greater than 6mm, fill by layering Osmo Woodfiller in 6mm increments. Drying: Let Osmo Woodfiller dry thoroughly. Use a heat gun or similar to speed drying time if desirable. (Osmo Woodfiller is properly dry if it sands to the consistency of talcum powder.) Sanding: Sand and remove all dust and debris. Staining: Apply stain to the floor (if staining). Do not rub the stain in with an aggressive action. Doing so will remove Osmo Woodfiller. Finish Coat: Apply Osmo or any final finish coat.

For Trowel Filling:

Mixing: If staining, use Osmo Woodfiller Natural/Clear. Otherwise match the colour to the wood. Mix Osmo Woodfiller in the tub with warm water (a mixer attached
to a heavy duty drill is ideal). Slowly pour the water in as you mix – usually about 15% water by weight. Mix until Osmo Woodfiller has the consistency of toothpaste.
Apply: Apply Osmo Woodfiller just before the final sand using a plastic trowel or rubber coat across the grain over the entire floor. Make sure the filler is forced into deep voids. Do not apply Osmo Woodfiller too heavily – a small amount goes a long way. Remove all excess Osmo Woodfiller. (Return excess to the Osmo Woodfiller container – no waste.) Drying: Let Osmo Woodfiller dry thoroughly. Use a heat gun or similar to speed drying time if desirable. Osmo Woodfiller is properly dry if it sands to the consistency of talcum powder.) Sanding: Final sand and remove all dust and debris. (If grain filling do not use a grit coarser than 120.)
Staining: Apply stain to the floor (if staining). Do not rub the stain in with an aggressive action; doing so will remove Osmo Woodfiller. Finishing Coat: Apply Osmo or any final finish coat.
