Description
Description
DAP Max Fill Expanding Foam Sealant is a high-performance solution designed to seal large gaps and voids with superior expansion and adhesion. Unlike traditional caulks and sealants, this one-component foam expands up to three times its original size, ensuring complete coverage for gaps over 1 inch wide. It forms a durable, weather-resistant bond that effectively blocks out drafts, moisture, and pests, improving energy efficiency and home comfort. Ideal for both interior and exterior applications, it can be painted after curing to blend seamlessly with surrounding surfaces. The included reusable adapter allows for multiple uses per can, reducing foam waste and providing more value for your projects. For best results, apply in temperatures between 60-100°F, avoid overfilling by filling only one-third of the gap, and clean spills immediately with acetone. Once dry, the foam can be trimmed, sanded, and painted for a professional finish. DAP Max Fill is an essential tool for homeowners and professionals looking to seal and insulate with ease, providing long-lasting protection against air and moisture infiltration.
