Product Description

The DAP INC 18741 is a 16-ounce advanced exterior filler designed for demanding exterior home repair and surface patching applications. Formulated with Weathermax Technology, it delivers weatherproof performance and UV protection to resist color fading, discoloration, cracking, and crumbling caused by harsh outdoor conditions. The compound bonds to a wide range of building materials, making it a versatile single-product solution for filling holes, cracks, crevices, dents, and surface defects. It is low in odor, sandable, and paintable after application, suitable for use by professional contractors, remodelers, and trade-qualified maintenance technicians.

This exterior filler is intended for residential and light commercial repair work on exterior surfaces exposed to weather and UV. It is well suited to filling surface defects on wood, metal, composite, PVC, fiber cement, mortar, concrete, vinyl, brick, stucco, plaster, and drywall.

Installation Notes

Surface preparation is critical before applying exterior fillers — clean the substrate of loose material, dirt, oil, and existing failed coatings before application. Power down any adjacent electrical equipment if working near penetrations or service entries. Allow the filler to cure fully before sanding or applying paint or primer topcoats. This product is typically applied by general contractors, remodelers, or maintenance technicians; follow all manufacturer cure-time guidance and local building code requirements for exterior repair materials.
