Waterproof Patch & Seal Paste, White, 1 Lb.

Gorilla Waterproof Patch & Seal Paste is a thick, flexible rubberized sealant paste that clings to multiple surfaces to instantly fill large gaps, cracks & holes. Make sure to clean surface of dirt, dust, grease and oil. Using putty knife or trowel, apply to the surface. Ensure surface is completely covered and all gaps and holes have been filled. Allow to cure in between coats. Full cure at 24-48 hours. Once applied, the high strength formula smoothly covers the surface tightly sealing out water, air and moisture, resulting in lasting repairs! NOTE: Slight skinning may occur inside can if lid is not sealed tight. If present, remove skinned material to continue use and secure lid immediately after use.
