Great for wetting out fiberglass fabrics and keeping them in position during layups

Tacky is good when you’re doing fiberglass layups and need to keep building layers without having them harden up on you. TotalBoat Polyester Laminating Resin will not cure on its own in direct contact with air. It contains no wax to prevent creation of an oxygen barrier that would cause it to cure, so it stays tacky and won’t sag while you’re building up layers. Its viscosity is ideal for wetting out fiberglass mat and cloth. Apply a final coat of TotalBoat Polyester Finishing Resin (which does contain wax) that cures to a hard, tack-free finish ready for sanding, painting, or gelcoating.

Gel time depends on amount of hardener admixed

The following table indicates approximate gel times @ 70°F. Adjust the hardener level to slow down or speed up gel time. Cooler temperatures may require a higher percentage of hardener than warmer temperature conditions.

Slow Gel Time Medium Gel Time Fast Gel Time
20 minutes or more 15-20 minutes 10 minutes
1 teaspoon of hardener per quart of laminating resin 2 teaspoons of hardener per quart of laminating resin 3 teaspoons of hardener per quart of laminating resin
