Dap Inc 21500 Plastic Wood Filler 1.875 Oz Tube

Product Description

The DAP INC 21500 is a cellulose fibre-based wood filler packaged in a 1.875 oz tube, formulated for filling, patching, and repairing wood surfaces in residential and light commercial settings. Its anti-shrink formula maintains fill integrity as it cures, reducing the need for second applications. Once set, the natural-color compound can be sanded, cut, drilled, planed, or whittled to match the surrounding surface profile. It also accepts stains, varnishes, paint, and lacquer, making it suitable for finish carpentry, cabinet repair, and millwork patching where a clean final appearance is required.

The 21500 is used by carpenters, finish trim installers, cabinet makers, and general contractors for wood repair tasks on doors, window frames, furniture, flooring, and structural wood members. Beyond wood, the compound bonds to metals, glass, and stone, expanding its use to mixed-material assemblies. It holds screws and nails after curing, making it a functional repair material and not just a cosmetic filler. The tube format offers controlled application with minimal waste on small patch jobs.
