Waterproof Expanding Polyurethane Glue, 2 oz, Brown

When a repair needs to hold fast indoors or out, reach for this trusted polyurethane glue. The moisture‑activated formula expands as it cures, driving deep into pores and creating a durable, long‑lasting bond on wood, stone, metal, ceramic, foam, glass, concrete, and more. The 2 oz bottle is sized right for toolboxes and quick fixes at home, in the shop, or on the jobsite.

Performance you can count on: this adhesive is 100% waterproof and temperature resistant, with a service range from -40° to 200°F, so bonds stand up to rain, heat, and cold. It dries tan to blend naturally with many woods and can be sanded, stained, or painted for a clean, finished look. Clamp for 1–2 hours and allow 24 hours for a full cure.

Quality shows in the details. This polyurethane adhesive meets ANSI/HPVA Type I water‑resistance standards and is engineered for reliable results. For best results, lightly dampen one surface, apply a thin layer of glue to the dry surface, then clamp firmly. Not recommended for polypropylene (PP) or polyethylene (PE) plastics.

Proudly crafted here at home, this glue reflects the work ethic and ingenuity that keep American projects moving—from weekend DIY to professional builds. Choose a bottle that helps support domestic manufacturing while delivering the toughness your projects deserve.
