Gorilla Waterproof Patch & Seal Paste is a thick, flexible rubberized sealant that clings to multiple surfaces to instantly fill large gaps, cracks, and holes. This high-strength formula seals out water, air, and moisture, making it ideal for stopping and preventing leaks on both wet and dry surfaces. Once cured, it provides a lasting, watertight repair that protects against the elements.
Whether you’re repairing a roof, gutter, skylight, flashing, chimney, PVC pipe joints, windows, RV seams, or tackling general DIY projects, this versatile sealant paste delivers professional-grade results. The spreadable consistency allows you to apply it easily with a putty knife or trowel, covering surfaces completely and filling even large voids. Because it can be painted once dried, you can finish repairs to match any color or surface for a polished appearance.
