General description Gorilla Glue is a high-strength polyurethane adhesive that provides a durable, waterproof bond. It is suitable for a wide range of materials including wood, stone, metal, ceramics, foam, glass, and leather. The glue expands upon contact with moisture, filling gaps and creating a strong, lasting bond. It is ideal for both indoor and outdoor repairs and projects, offering resistance to extreme temperatures and weather conditions. Once dried, the adhesive is sandable, stainable, paintable, and varnishable.
