Directions Instrucciones en Español

  1. Area must be clean, dry and free from paint varnish, dirt, and grease. If working with rotted or soft wood, remove loose material and apply Minwax®High Performance Wood Hardener to strengthen wood fibers and to form a solid base for filling.
  2. Scoop a golf ball size amount of filler into plastic lid and squeeze in a thin 3/4 inch long line of hardener from the tube. Mix thoroughly. (Mix only as much as can be used in 15 minutes.)
  3. Apply the mixed paste immediately to the area to be repaired. Spread on a thin layer followed by sufficient product to fill the gap. Slightly over-fill to allow for sanding down. Work quickly as the mixture remains workable for about 10 minutes at room temperature. (To fill deep holes, spread on 1/8 inch thin layers one at a time until the hole is filled.)
  4. After approximately 20 minutes, the repair should be hard enough to be carved and shaped using a sharp modeling knife.
  5. Wait at least 30 minutes to sand, plane or file.
  6. The Minwax® High Performance Wood Filler can then be painted.

Frequently Asked Questions

Can Minwax® High Performance Wood Filler be stained?

Staining High Performance Wood Filler is not recommended. Minwax® High Performance Wood Filler accepts stain differently than wood does. It is unlikely that a close color match will be achieved. For repairs that require an exact stain match, use Minwax® Stainable Wood Filler
