It’s also important to use gorilla glue in a well-ventilated area and avoid any contact with flames or sparks. In case of accidental exposure to fire, do not attempt to extinguish it with water as it can cause a potentially dangerous chemical reaction. Instead, use a dry chemical fire extinguisher or cover the flames with sand or baking soda.

How does gorilla glue work?

Gorilla Glue works through a chemical reaction triggered by the presence of moisture, both in the air and on the surfaces being bonded. This reaction causes the glue to undergo a process of polymerization and curing, transforming from a liquid to a solid state. The glue expands slightly during this process, filling in microscopic gaps and creating a very strong mechanical bond. Its efficacy lies in its ability to bond to a wide variety of materials, including wood, metal, stone, ceramics, foam, glass, and more, making it exceptionally versatile for both household repairs and professional projects.

Gorilla Glue is a powerful adhesive that works through a chemical reaction triggered by moisture. This unique feature allows it to create strong bonds on various surfaces, making it a go-to product for both DIY enthusiasts and professionals.
