Gorilla Glue 105338 Hybrid Polymer Caulk Sealant 32 Fl Oz

Product Description

The GORILLA GLUE 105338 is a hybrid polymer caulk and sealant supplied in a 32 fl oz can. It delivers a flexible, weatherproof seal across a wide range of substrates and exposure conditions. The formula reaches a tack-free state in approximately 80 minutes and achieves full cure within 24 to 48 hours. Once cured, it remains stable from -40 degrees F up to 212 degrees F, making it suitable for both seasonal temperature swings and sustained heat exposure. The black color blends with common roofing and flashing materials. Plumbers, roofers, general contractors, and experienced DIYers all use this product for leak prevention and surface sealing.

This sealant is rated for both indoor and outdoor use. Typical applications include roofs, gutters, skylights, flashing, chimneys, PVC pipe joints, windows, and RV surfaces. The hybrid polymer chemistry bonds to a broad range of materials, allowing a single product to handle multiple sealing tasks on the same job site. It is part of the Patch and Seal series, which is aimed at repair and maintenance scenarios where a durable, flexible bond is required.
