Minwax 21600 High Performance Wood Filler 12 Oz

Product Description

The MINWAX COMPANY, THE 21600 is a two-component, high-performance wood filler formulated for repairing damaged, rotted, or missing wood on interior and exterior surfaces. This product uses a two-part system that, once mixed, delivers a durable, sandable, and paintable fill that resists shrinkage and cracking. Each container holds 12 oz of filler material. The 21600 is suited for finish carpenters, general contractors, and experienced DIYers working on millwork, trim, siding, doors, and structural wood repair where a strong, stable fill is required.

This wood filler is appropriate for both residential and light commercial applications. It works on window sills, door frames, porch columns, exterior trim, and other wood surfaces subject to weathering or physical damage. The two-component formulation cures to a hard, workable mass that can be shaped, carved, drilled, and painted like wood. It is typically used where standard single-component fillers lack the structural integrity needed for the repair.

Installation Notes

Application is typically performed by finish carpenters or general contractors following standard surface preparation practices. The substrate should be clean, dry, and free of loose material before mixing and applying the two-component filler. Mix only the amount needed for immediate use, as the product begins to cure after components are combined. Follow all manufacturer mixing ratio instructions printed on the packaging and wear appropriate personal protective equipment during handling.
