Minwax 21600000 High-performance Wood Filler, 12 Oz.

Minwax High-Performance Wood Filler is a two-component wood repair compound designed to permanently restore damaged, rotted, or deteriorated wood surfaces. This 12-ounce filler combines a resin base with a hardener to create a durable, rock-solid repair that resists shrinkage, cracking, and moisture infiltration. Whether you're fixing split wood, filling deep gouges and holes, or repairing rotted sections in window sills, door frames, or exterior siding, this professional-grade filler delivers lasting results on both interior and exterior wood.

The advanced formulation addresses common wood repair challenges: it won't shrink or crack as it cures, won't soften or swell from humidity or moisture exposure, and bonds strongly to all types of wood including hardwoods, softwoods, and engineered boards. Once hardened, the filler sets to a smooth surface ready for sanding and finishing, then painted, stained, or sealed with varnish.

Features and Benefits

• Two-Component System: Resin and hardener combine for a chemical cure that produces an impact-resistant, durable bond with wood fibers.
• Non-Shrinking Formula: Maintains its shape and size as it cures, eliminating the gaps and sunken spots common with single-part fillers.
• Moisture-Resistant: Prevents swelling, softening, or deterioration in humid environments or outdoor applications.
• Sandable Surface: Hardens to a smooth, sand-ready finish that can be shaped to match surrounding wood.
• Accepts Finishes: Can be painted, stained, or sealed without blotching or rejection once fully cured.
• Easy Mixing: The 12-ounce measured container mixes evenly in minutes, reducing waste and simplifying application.
