Waterproof Polyurethane Glue Single-Use, Brown

When you need a small amount of serious holding power, this single-use polyurethane adhesive delivers. Its moisture-activated formula expands into material pores and creates a durable, long-lasting bond on both porous and non-porous surfaces. The compact, use-and-toss tube helps ensure fresh glue every time with less mess and no clogged caps.

Ideal for home repairs, woodworking, outdoor fixtures, crafts, and DIY builds, it works across wood, metal, stone, ceramic, foam, glass, concrete, and more. Clamp for 1–2 hours and allow 24 hours for full cure; once cured, the bond is 100% waterproof and holds through hot and cold temperatures from -40°F to 200°F.

Quality matters: this adhesive meets the ANSI/HPVA Type I water-resistance standard, cures to a natural brown/tan color, and can be sanded, stained, and painted (oil-based or spray; acrylic/latex paints and stains may require sanding). For best results, apply above 40°F to clean, tight-fitting surfaces and lightly dampen one surface before gluing.

Engineered for reliability you can trust, it’s a smart addition to any toolbox, jobsite kit, or junk drawer. Proudly made in the USA with domestic and global materials, it supports American manufacturing while delivering pro-grade performance for everyday users.
