Developed by boaters for boaters, to provide great value and great results

We’ve used our years of experience to make the TotalBoat 5:1 system of marine-grade epoxy resin, hardeners, and fillers as DIY-friendly as possible. From the way it’s measured and mixed, to the thickening agents you can mix in to make it do what you want it to do. One pump of resin and one pump of hardener is all you need to get the proper 5:1 mix. For bigger batches, it’s just as easy to measure precise amounts by weight or by volume. No guessing that might result in unusable glop.

Get the right combination of resin, hardener, and filler for your particular project

Because it’s so strong and versatile, there are many things you can build or fix with our 5:1 marine epoxy resin. From bonding and coating, to laminating and fairing, we have a comprehensive line of hardeners and fillers to suit the job. TotalBoat 5:1 epoxy resin formula is also 100% compatible with other traditional 5:1 marine epoxy systems. Use it with other or specialty hardeners and fillers without worry.

Packaged to reduce waste and save money

TotalBoat epoxy is packaged so nothing gets wasted. For example, the Size A 5:1 Epoxy Resin and the Size A Hardener are made so when they are dispensed 5:1, the packages will empty at the same time, so there’s no wasted product. When you buy more, you can reuse your existing pumps. And because you can use TotalBoat 5:1 Epoxy Resin interchangeably with other traditional 5:1 epoxy systems, you can mix and match to use up the products you already have.
