Polyester Laminating Resin for Marine Fiberglass Layups and Repairs (Gallon)

The surface tackiness is crucial when you're rapidly stacking layers of fiberglass and resin for a build or repair, as you don't want the layers to cure yet. TotalBoat Polyester Laminating Resin remains tacky, enabling the layers to form strong bonds without hardening up in the middle of your project. This economical, marine-grade fiberglass resin does not contain wax, ensuring it won't cure in direct contact with air. It can be applied to prepared fiberglass, wood, and metal, making it suitable for various projects, such as a spray-up in a mold, a hand layup on a boat, or DIY fiberglass repair on your boat hull, surfboard, car body, motorcycle, RV, or bathtub.

The DIY fiberglass laminating resin has an ideal viscosity for wetting out fiberglass mat, fiberglass cloth, and carbon fiber, without sagging, even on vertical surfaces. It also minimizes pattern print-through on gelcoat finishes, making it an excellent choice for your fiberglass or gelcoat repair kit. TotalBoat Laminating Resin is easy to use but requires MEKP catalyst (included) to function properly. Simply add the catalyst, stir thoroughly, and use immediately. To control the working time, you can adjust the amount of MEKP hardener. For example, at 70°F, for a working time of 20 minutes or more, add 1 teaspoon of MEKP to 1 quart of polyester resin; for a working time of 15-20 minutes, add 2 teaspoons of MEKP to 1 quart of resin; for a working time of 10 minutes, add 3 teaspoons of MEKP to 1 quart of resin. When you're ready for it to cure, apply a final coat of TotalBoat Polyester Finishing Resin for a hard, tack-free finish ready to sand, paint, or gelcoat.

TotalBoat Polyester Laminating Resin is available in Quart and Gallon sizes, with the MEKP catalyst included. It can be compared to products from 3M, Bondo Fiberglass Resin, FSD Fiberglass Supply Depot Polyester Resin, and Polymer Planet Polyester Fiberglass Resin. This resin is 100% made in the USA.
