How to use Brummer Exterior Wood

  1. Wood should be sanded smooth, clean and free from wax. If wood is to be painted, it should be primed before the Wood Filler is applied.
  2. Apply the filler using a putty knife, forcing into the cracks and holes.
  3. Leave slightly proud of the surface to allow for possible shrinkage.
  4. Sand off any excess.
  5. Brummer Exterior Wood Filler is supplied ready for use, but if it becomes hard, adding a little methylated spirit may soften it.
  6. Allow to dry for about 1 hour, depending on temperature, then sand smooth.
  7. If the hole to be filled is quite deep, it may be filled in stages to minimise shrinkage.
  8. Deeper holes will need extended drying periods.
  9. If applying a clear finish, Brummer exterior Filler can be disguised by painting a pattern onto the dry filler with artists acrylic colours before varnishing.
  10. Leave to dry for 1 hour before applying undercoat or varnish. Deep filled area will require longer drying times.
