Minwax High Performance Wood Hardener 1 pt.

Minwax High Performance Wood Hardener is a clear, non-pigmented liquid formula designed to penetrate and reinforce soft, porous, or decayed wood.

Whether you're restoring antique furniture, repairing window sills, or refreshing exterior trim, this wood hardener delivers reliable strength and prepares wood for lasting refinishing.

Formulated for easy brush-on application, it penetrates deep into the grain to bond loose fibers and lock in structural integrity. Dries rapidly in 2–4 hours to a hard, sandable surface, allowing you to move quickly from repair to finishing.
