Dap Inc 21408 Plastic Wood Filler 4 Oz Golden Oak

Product Description

The DAP INC 21408 is a solvent-based, cellulose fibre wood filler in a 4 oz container with a Golden Oak color finish. It hardens to form a surface body that closely replicates the look and structural behavior of real wood. Once cured, it accepts sanding, staining, cutting, drilling, planing, varnishing, painting, and lacquering. Rated for both interior and exterior applications, this filler meets Federal Specification TT-F-340C. It is a practical go-to for carpenters, finish contractors, and maintenance professionals who need a reliable wood repair compound on the job site or in the field.

The 21408 is suited for repairing cracks, gouges, and scratches in wood surfaces across residential and light commercial settings. Its formulation is especially effective for large, deep holes where surface-level fillers fall short. Because it bonds firmly and accepts finish work, it fits naturally into trim repair, door and window frame restoration, furniture repair, and general millwork patching on both painted and stained wood surfaces.

Installation Notes

Application is typically performed by carpenters, finish contractors, or maintenance technicians. Work in a well-ventilated area, as the solvent-based formula releases fumes during application and curing. Clean the repair area of loose material and debris before applying the filler. Allow the product to fully cure before sanding, drilling, or applying any finish coat.
