Gorilla Glue 5000408 Expanding Glue 4 Oz Indoor Outdoor

Product Description

The Gorilla Glue Company 5000408 is a 4 oz expanding polyurethane adhesive formulated for high-strength bonding across a wide range of surfaces and materials. The glue expands as it cures, filling gaps and creating a mechanical bond that holds firmly to wood, stone, metal, ceramic, foam, glass, and more. It cures to a rigid, sandable, paintable finish, making it suitable for both structural repairs and surface-finishing work. Contractors, maintenance technicians, and experienced tradespeople reach for this adhesive when standard glues fall short on porous or dissimilar-material joints.

This adhesive is designed for both indoor and outdoor applications. The waterproof cure makes it appropriate for exterior repairs, outdoor furniture, plumbing fixture surrounds, and any install where moisture exposure is expected. It is also well-suited for interior millwork, subfloor patching, cabinet repairs, and general construction tasks. The 4 oz bottle size is practical for single-job or small-batch use on the jobsite or in the shop.

Compatibility

Designed as a general-purpose expanding polyurethane adhesive compatible with porous and non-porous surfaces including wood, metal, stone, ceramic, foam, and glass in residential and commercial construction and maintenance applications.

Installation Notes

Apply to a clean, lightly dampened surface for best adhesion, as moisture activates the curing reaction in polyurethane adhesives. Clamp or secure bonded parts for the full cure period and avoid moving the joint during cure. Work in a well-ventilated area and wear appropriate gloves, as uncured polyurethane adhesive bonds to skin and is difficult to remove. Store the bottle sealed and upright to prevent premature curing of residual adhesive in the tip.
