FAQ

Q. 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 and exact stain match, use Minwax® Stainable Wood Filler.

Q. How is Minwax Wood Putty® different from Minwax® High Performance Wood Filler?

Unlike Minwax® High Performance Wood Filler, Minwax Wood Putty® is a non-hardening putty designed to cosmetically fill nail holes, joints and other minor surface imperfections. Additionally, Minwax Wood Putty® is color-matched to the Minwax® Wood Finish™ stain line. Minwax® High Performance Wood Filler is a heavy-duty filler that repairs damaged or rotted wood.

Directions

WARNING! Removal of old paint by sanding, scraping or other means may generate dust or fumes that contain lead. Exposure to lead dust or fumes may cause brain damage or other adverse health effects, especially in children or pregnant women. Controlling exposure to lead or other hazardous substances requires the use of proper protective equipment such as a properly fitted respirator (NIOSH approved) and proper containment and cleanup. For more information, call the National Lead Information Center at 1-800-424-LEAD (in US) or contact your local health authority.

Directions

  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 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 or stained. To stain Minwax® High Performance Wood Filler, see tips for staining Minwax® High Performance Wood Filler inside cap sticker.

Cleanup: acetone following manufacturer's safety instructions.

Note: This product absorbs stain differently than wood. Therefore, it is unlikely that exact color match to the original wood will be achieved.
