glassSTEEL is a flexible, fiber reinforced polymer sheet that cures with UV light to be hard like steel. It can be bonded to nearly any rigid surface such as concrete, metal, steel, glass, piping, fiberglass, polyethylene, wood and more. Product hardens in minutes, with little to no down time. Flexible sheets can be cut with scissors or knife and have a translucent quality to show air bubbles and surface below when bonding. With flashlight UV activation, sheets cure in 5 minutes or can be cured by the sun. When hard, patches can be sanded, painted and drilled. Shelf stable, each patch comes in a resealable bag, use only what you need and save the rest for your next quick maintenance repair!
