TotalBoat High Performance Fast Hardener is the curing agent for low-viscosity TotalBoat High Performance Epoxy Resin for the fastest cure at room temperature, or for overnight cure in low temperatures (minimum 55°F)
At 77°F, this non-blushing hardener has a pot life of 10 minutes, will be tack-free in approximately 2 hours, and reaches full cure in 2 days.
Pairing TotalBoat High Performance Resin with the Fast Hardener results in a moisture-resistant clear finish, ideal for clear coating applications. No blush to remove between coats means no time-consuming washdowns and no worrying about whether you removed all the blush, which could cause improper cure.
This Fast Hardener is available in Group Size A (pint), B (half gallon), and C (gallon), to match the group sizes of TotalBoat High Performance Epoxy Resin, which reduces waste and saves money.
Note: Fast hardener is also available in a 26.1 gallon container, for use with drums of High Performance Resin. Please contact us for pricing.

Three Hardener Speeds Let You Control Pot Life and Cure Time
Fast, Medium, and Slow High Performance Hardeners allow you to control the pot life and cure times to suit your particular working conditions.
Even better, you can craft your ideal working properties and pot life by combining the different hardeners with each other, but always remember to maintain the proper ratio of 2 parts resin to 1 part hardener by volume.
Which High Performance Hardener Should I Use?
IMPORTANT! In order to achieve a proper cure, accurate mix ratios are critical when working with epoxy resin and hardeners.
TotalBoat High Performance Epoxy Resin and TotalBoat High Performance Hardeners can be measured either by pouring or by using the calibrated TotalBoat 2:1 Epoxy Pumps (sold separately). If using the pump method for dispensing, USE ONLY TOTALBOAT 2:1 Epoxy Pumps. DO NOT substitute the pumps from any other epoxy system or the material will not cure properly.
NOTE: The procedure for dispensing TotalBoat High Performance Epoxy Resin and TotalBoat High Performance Hardener properly is always ONE full pump of resin to ONE full pump of hardener.
