FAQ

Q: How does Minwax® High Performance Wood Hardener work?

Minwax® High Performance Wood Hardener's extra hard resin is dissolved in a solution of solvents.  These solvents carry the resin deep into the pores of the wood where they quickly evaporate leaving behind the hardened resin resulting in hardened 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.

  1. Completely remove decayed and very soft, crumbly wood until you reach reasonably sound wood.  Wood should be dry, free from dirt, grease, oil and loose paint particles.
  2. Shake can well; apply Minwax® High Performance Wood Hardener with a disposable bristle brush to the softened wood to completely saturate the area.
  3. For strength, apply several coats in quick succession until a shiny surface appearance is obtained.
  4. Allow to harden for 2-4 hours before filling void with Minwax® High Performance Wood Filler.
  5. Sand, paint, or stain if desired.

Clean up: disposable bristle brush is recommended.  If not available, clean the brush with acetone, following manufacture’s safety instructions
