What is Epoxy?
Boat builders, surfboard makers and fabricators of all kinds use epoxy every day to form strong, waterproof, lightweight structures. And you can take advantage of this versatile group of products around the home, too. Epoxy for household use is available in liquid, gel and putty and in containers ranging from a mere half ounce to gallons.
Unlike many other adhesives and fillers that require drying time, epoxies require two parts that, when mixed, begin a chemical reaction that causes the liquid or putty to harden. The amount of time you have to work with the epoxy before it sets up is determined by the chemistry of the hardener. For tiny jobs, you can choose one-minute epoxy, but in general, epoxy that takes longer to set also forms a stronger bond, not to mention giving you more working time.
