Gorilla Glue 109406 Hybrid Silicone Caulk Sealant 1 Lb White

Product Description

The GORILLA GLUE 109406 is a hybrid silicone modified polymer caulk sealant designed for waterproof patching and sealing across a wide range of surfaces and conditions. Packaged in a 1 lb can, this white sealant delivers a tack-free dry time of 5 to 30 minutes and reaches full cure in 24 to 48 hours. It operates reliably from -40 degrees F up to 212 degrees F, making it suitable for demanding exterior environments. Once cured, the sealant accepts paint, allowing finish work to proceed without visible sealant lines. HVAC technicians, plumbers, roofers, and general contractors reach for this product when a flexible, weatherproof seal is needed across dissimilar materials.

This sealant is rated for both indoor and outdoor use. Primary applications include roofs, gutters, skylights, flashing, chimneys, PVC pipe joints, windows, and RV sealing. It bonds to aluminum, brick, concrete, glass, metal, rubber, tile, and wood, covering the broad mix of substrate combinations commonly encountered on residential and light commercial service calls. The series is marketed as Waterproof Patch and Seal, reflecting its role as a field repair and installation sealant rather than a structural adhesive. A single 1 lb can provides coverage of 257 square inches.

Installation Notes

Surface preparation is critical — clean and dry all substrates before applying sealant to ensure proper adhesion. On exterior applications such as chimneys and flashing, confirm the surface is free of existing loose caulk, dirt, and moisture. Apply within the manufacturer-stated temperature range for best adhesion results. Allow full cure time of 24 to 48 hours before exposing the joint to water or mechanical stress.
