It stays tacky between coats to ensure strong bonding without sanding, includes adjustable MEKP hardener for customizable gel times, and features a medium-high viscosity ideal for wetting out fiberglass on vertical and complex surfaces. Available in gallon size, it’s perfect for boat hulls, surfboards, automotive, and more, delivering water resistance and a smooth finish. Made in the USA with a 4.6-star rating, it’s a trusted choice for durable composite fabrication and repair. ## Description Surface tackiness is key when you're stacking up layers of fiberglass and resin fast for a build or repair and don’t want the layers to cure yet. TotalBoat Polyester Laminating Resin stays tacky, allows the layers to form strong bonds and won’t harden up on you in the middle of your project. This economical, marine-grade fiberglass resin doesn’t contain wax, so it won’t cure in direct contact with air. It can be applied to prepared fiberglass, wood, and metal, so it’s perfect for projects like 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. DIY fiberglass laminating resin has a viscosity ideal for wetting out fiberglass mat, fiberglass cloth and carbon fiber, and it won’t sag - even on vertical surfaces. It also minimizes pattern print-through on gelcoat finishes, making this resin ideal for your fiberglass or gelcoat repair kit. TotalBoat Laminating Resin is easy to use but requires MEKP catalyst (included) to work properly. Just add catalyst, stir thoroughly, and use immediately. To control 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, includes MEKP catalyst.
