Gorilla Original Waterproof Polyurethane Glue 36oz Pack of 3 - Tough

In this review of Gorilla Original Waterproof Polyurethane Glue, a pack of three 36oz bottles, the bottom line is simple: this is a go-to adhesive for heavy-duty household repairs where strength and versatility matter most. The reviewer found it especially useful for bonding dissimilar materials like wood to metal or stone to ceramic, and highlights the glue's reputation as a leading multi-purpose, waterproof polyurethane adhesive. While not perfect for every quick craft, it shines on tough fixes that need a durable, long-lasting hold.

Key Features

• Versatile bonding: Bonds wood, stone, metal, ceramic, foam, glass and concrete, which reduces the need to keep multiple specialty adhesives on hand.
• Waterproof formula: Designed to hold up indoors and out, making it suitable for exterior repairs and moisture-prone areas.
• High strength: The polyurethane chemistry creates an incredibly strong bond for demanding repairs on dissimilar surfaces.
• Large volume: Each bottle is 36oz and the pack of three provides enough adhesive for many projects, saving frequent reordering.
• Multi-purpose use: Works for household fixes, workshop projects and heavier construction touch-ups where a strong all-around glue is preferred.

Who It's For

This product is aimed at homeowners, hobbyists and light contractors who need a single adhesive capable of handling varied materials and outdoor exposure. If you frequently repair furniture, patch concrete, bond mixed substrates or want a dependable waterproof glue on hand, this pack provides value through volume and capability.

Those who need an ultra-fast-drying adhesive for delicate crafts or precise assembly of small parts should look elsewhere, as polyurethane glue can foam or expand during cure and may require clamping and cleanup. Also, users expecting instant tack like superglue will find this glue works differently.
