TotalBoat High Performance 2:1 Epoxy Resin and 2:1 Non-Blushing Hardeners can be poured (to measure by weight or volume), or dispensed in exact measure using TotalBoat 2:1 Epoxy Pumps. Our 2:1 Epoxy Pumps are intended for use only with TotalBoat 2:1 epoxy resin and hardener containers, and they will not fit other marine 2:1 epoxy resin and hardener containers.

Which TotalBoat 2:1 Hardener Do I Need for My Project?

2:1 Fast Hardener – Use 2:1 Fast Hardener for the fastest cure and shortest working time at room temperature, or for an overnight cure in low temperatures (minimum 55°F).

2:1 Medium Hardener – Use 2:1 Medium Hardener for most common applications, or for an overnight cure at room temperature (77°F).

2:1 Slow Hardener – Use 2:1 Slow Hardener for extended working time and cure time at room temperature, or when working in warmer temperature conditions. If you are new at working with epoxy resin, the slow speed hardener will give you more working time, which you may find helpful.

Even better, you can customize pot life and cure time further by combining the different hardeners with each other. Just remember to always maintain the proper ratio of 2 parts resin to 1 part hardener by volume.
