Product Description

The GORILLA 109406 is a waterproof patch and seal paste used to stop leaks and seal gaps on a wide range of surfaces.

Weighing 1.317 pounds, it is sized for field repairs and on-the-job patching tasks.

Installation Notes

Surface preparation is critical before applying paste sealant - clean, dry, and free of loose material and contaminants for best adhesion. Apply using a putty knife, trowel, or gloved hand, working the paste firmly into the repair area. Allow full cure time before exposing the repair to water or moisture. Follow all applicable local building and mechanical codes when sealing penetrations or joints in regulated systems.
