What Is ClearWeld?

Like other epoxies, ClearWeld is a two-part component adhesive. It requires a 1:1 mix, which when dispensed through the syringe, comes out perfect every time. Once set, you have just under 5 minutes to apply and adjust the epoxy, and it cures fully in 1 hour, so repairs are quick and easy. With a strength of 4,400psi, ClearWeld provides a strong, lasting bond.

Getting Started

As with any repair, prep is the key to success. Start off by cleaning the parts to be repaired with a detergent or degreaser. Next, rough up the surfaces with a bit of 80-grit sandpaper. This gives the epoxy something to grab onto.
