DAP Platinum Patch Advanced Exterior Filler 16 oz. White

DAP Platinum Patch Advanced Exterior Filler is a professional-grade, all-weather repair paste designed to restore and protect exterior surfaces. Formulated with innovative WeatherMAX® technology, it delivers exceptional weatherproofing, UV resistance and a tough, hydrophobic barrier that won’t crack, crumble or discolor—even under continuous exposure to rain, sun and temperature extremes.

Ideal for a wide range of substrates—from fiber cement siding and PVC trim board to metal, wood, brick, concrete and vinyl—this 16 oz. white filler bonds firmly to porous and non-porous materials. It cleans up easily with water, dries low-odor and, once cured, can be sanded smooth and painted to blend seamlessly with any exterior finish.
