18740 Weatherproof Patching Compound, White, 16 Oz.

Dap Weatherproof Patching Compound is an advanced exterior filler formulated with Weather Max Technology for long-lasting protection in all weather conditions. This spackling paste is designed to repair and fill holes, cracks, gaps and deteriorated areas on a wide variety of exterior surfaces, from fiber cement siding and vinyl siding to PVC trim, metal, composite, concrete, brick, stucco and wood. The weatherproof formula prevents discoloration, cracking and crumbling while resisting mold, mildew and algae growth—making it ideal for areas exposed continuously to sun, rain and moisture.

The compound's tough hydrophobic surface creates a waterproof repair that won't swell, soften, blister or break down over time. It bonds reliably to both porous and non-porous materials, delivering strong multi-material adhesion that won't crack or lose grip as it cures. The easy-apply texture reduces mess and effort, and it maintains strength without shrinking as it dries. Once cured, the patched area is sandable and paintable for seamless finishing, while cleanup is simple with just water.
