The tough, water-resistant cure for whatever unfloats your boat
Have a chainplate that busted out of its bulkhead? A motor mount that came unmounted? Delaminated deck material? Cracks in your cuddy? No matter what shape your ship’s in, there are several projects epoxy can handle. It’s strong and won’t shrink in the face of daunting repairs. Literally. There’s nominal shrinkage, especially in larger repairs like replacing large sections of laminate. TotalBoat 5:1 Epoxy cures to a high-strength, water-resistant solid ideal for use in a variety of epoxy repair and fiberglass projects, including coating, bonding, and laminating. Add our fillers to the resin/hardener mix to get a strong adhesive, or a fairing and filleting compound that sands easily once cured.
Our epoxy resin kits make doing it yourself even easier
Whether you’re reinstalling berth frames and bulkheads, or you have an old wooden boat that needs some new skin, there’s enough stuff in our kits to make tough projects easier. You get the 5:1 Epoxy Resin and your choice of either Fast or Slow Hardener. Use the Fast Hardener in cooler temperature conditions to give you adequate working time and to speed up the curing time. The Slow Hardener extends the working and cure times in warmer temperatures. These complete, project-ready kits also have a set of calibrated pumps to dole out the resin and hardener in the precise mix of 5 parts resin to 1 part hardener. If you only need the 5:1 Epoxy Resin and Hardener, there’s a kit for that, too.
Our Traditional Formula is Compatible with Other 5:1 Marine Epoxy Systems
Still have another brand of resin or hardener left over from previous projects? You can use TotalBoat 5:1 components interchangeably with other 5:1 fiberglass epoxy systems, letting you mix-and-match to use up those leftovers. Just remember that other brands' pumps are not compatible - only use the included TotalBoat 5:1 Epoxy Pumps.
Calibrated Pumps for a Perfect 5:1 Ratio in a Single Pump
While this fiberglass epoxy resin can easily be measured by weight or volume, the included color-coded pumps simplify the math by achieving a 5:1 ratio in a single pump. The white resin pump and black hardener pump are calibrated to automatically dispense the needed ratio for each component. Pump the needed amount into a mixing cup and stir for two minutes using the two-cup method to create professional-level results and waste less product.

FREQUENTLY ASKED QUESTIONS
-
What is the difference between Fast Hardener and Slow Hardener?
Use the Fast Hardener in cooler temperature conditions to speed up curing time while still providing adequate working time. The Slow Hardener extends the working and cure times in warmer temperatures. Slow Hardener is not recommended for use in cool temperatures. -
Is TotalBoat 5:1 Epoxy UV-protected?
All epoxies will discolor, turn brittle, and eventually disintegrate upon prolonged UV exposure unless topcoated with a UV-resistant varnish or polyurethane finish. Be sure to sand cured epoxy before topcoating. -
Should I sand epoxy between coats?
When applying additional coats of resin to dried epoxy, sanding improves the mechanical bond. Before sanding, be sure to remove any amine blush. Once cured, this epoxy can be sanded and shaped. -
Is Traditional 5:1 Epoxy Resin Kits a non-blushing system?
No, it will blush upon cure. Amine blush is a normal byproduct of curing and is easily removed. -
Can this epoxy resin be thinned?
Do not thin TotalBoat 5:1 Epoxy; we recommend Penetrating Epoxy if you need a thin or low-viscosity epoxy. -
How should I apply this resin?
You can apply epoxy resin with a brush, roller, or syringe. It can also be poured and spread with an epoxy spreader. -
Does TotalBoat Traditional Epoxy dry clear?
TotalBoat 5:1 epoxy cures to a slight amber color. It is not intended for clear coat applications. We recommend High Performance 2:1 Epoxy for applications where the clearest possible finish is important -
How many square feet will a one-gallon system cover?
Using typical 6 oz fiberglass cloth, a gallon of resin will cover about 10 sq yards or 90 sq ft of cloth. -
Is this resin compatible with fillers?
Yes. All common fillers like cabosil, wood flour, milled glass fibers, microballoons, and others may be added to 5:1 Epoxy to create compounds used for fillets, fairing, bonding, and gap filling. -
What is the minimum temperature suggested for working with this product?
The minimum recommended temperature for the Fast Hardener is 40°F. The minimum recommended temperature for the Slow Hardener is 60°F. -
Is TotalBoat Traditional 5:1 Epoxy compatible with other epoxy systems?
Yes, TotalBoat 5:1 Epoxy can be used interchangeably with other traditional 5:1 marine epoxy systems. Important: Do not use TotalBoat pumps with other brands. Be sure to mix by volume only. -
What is the working time?
Pot life ranges from 12 minutes at 75°F for Fast Hardener, to 20 minutes at 75°F for Slow Hardener. Set time ranges from 6 hours at 75°F for Fast Hardener, to 10 hours at 75°F for Slow Hardener. Cure time ranges from 1-4 days at 75°F for Fast Hardener and Slow Hardener. -
Will epoxy still cure if mixed at an incorrect ratio?
No, unlike polyester resin, epoxies require a very specific resin to hardener ratio in order to cure properly. You will need to remove the epoxy and start over. Solvents like acetone may be used to remove the uncured resin. -
How should I properly store TotalBoat epoxy?
Store at 60-90°F in a dry place. After use, tightly reseal all containers. Store products on a raised surface off the floor during cold weather and avoid storing near outside walls or doors. Properly stored, this epoxy has no specific shelf life.
