Waterproof Patch & Seal Paste

Gorilla Waterproof Patch & Seal Paste is a thick, flexible rubberized sealant paste that clings to multiple surfaces to instantly fill large gaps, cracks and holes. The high-strength formula tightly seals out water, air and moisture for lasting repairs on automotive, marine and household projects.

Capacity and headroom

The 1 lb container provides enough material for multiple medium-sized repairs such as sealing roof vents, patching boat hulls or fixing gutter joints. It handles wide gaps and deep cracks in a single application but very large voids may require more than one tub or a backing material.

Thermals, noise and power draw

The paste applies between 40F and 120F, skins over in 15 to 30 minutes and reaches full cure in 24 to 48 hours. No mixing, heating or powered tools are needed, so there is no electrical draw or operational noise during use.

Questions about this item

Will this paste stick to the old silicone caulk I already have around the window frame?

The rubberized formula clings to multiple surfaces, so it can bond to cured silicone after the area is cleaned of dirt, dust, grease and oil.

How do I know the 1 lb black paste has fully cured after I apply it?

It skins over in 15 to 30 minutes and reaches full cure at 24 to 48 hours, forming a flexible waterproof seal.

Does the 1 lb can include a putty knife or do I need to buy one separately?

The can contains only the sealant paste; a putty knife or trowel is required for application and must be purchased separately.
