Original Formula Gorilla Glue is tough, expanding and sticks to everything. It is incredibly strong and ideal for indoor and outdoor applications. Known for its industrial holding power and versatility, regardless of the surface, Gorilla Glue is 100 percent waterproof and doesn't break down when exposed to outdoor elements. It easily bonds wood, stone, metal, ceramic, foam, glass, concrete and much more. The water-activated polyurethane formula expands three times into the materials to form an incredibly strong bond. Bond holds through hot and cold temperatures. Clamp time is 1 to 2 hours. <p><a id="gfk-spex-minisite" rel="nofollow" href="javascript:void(0)" onclick="javascript:window.open('//content.etilize.com/mini-site/en_us/1064679595.html', '_blank', 'height=800, width=780, resizable=yes, scrollbars=yes, toolbar=no, menubar=no, location=no, directories=no, status=no'), return false, ">More from the Manufacturer</a></p>
