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.

Frequently Asked Questions
Does the epoxy resin come with a hardener?
No, hardener must be purchased separately. We recommend TotalBoat 5:1 Epoxy Kits, which contain both resin and hardener.
Do I have to mix the resin with a hardener, or can I use it by itself?
All epoxies need to be mixed with the correct hardener, at the specified mix ratio, or the resin will not cure.
Is TotalBoat resin compatible with other epoxy systems?
Traditional 5:1 resin is designed for use with either TotalBoat 5:1 Slow Hardener or TotalBoat 5:1 Fast Hardener but it is also 100% compatible with common marine 5:1 epoxy systems. Do not use with other resin systems specifying a mix ratio other than 5:1.
Can I use 5:1 epoxy over penetrating epoxy sealer?
Yes. Allow the penetrating epoxy to cure completely, wash it with mild soap and water, then dry. Rough the surface with 80-grit sandpaper and then apply the Traditional 5:1 Epoxy.
Does resin include a pump?
Purchasing any TotalBoat resin alone will not include pumps. TotalBoat Epoxy Kits normally include pumps.
How should I apply resin?
You can apply the epoxy resin with a brush, roller, or syringe. It can also be poured and spread with an epoxy spreader.
Does the epoxy dry clear or does it carry a color?
The 5:1 epoxy resin itself is clear in color. However, admixed with TotalBoat 5:1 Fast, Slow, and 3:1 Tropical hardeners will yield an amber hue, while the TotalBoat Crystal Clear Hardener will have a clear finish.
How should I properly store the resin?
Store the resin at 60-90°F in a dry place. After use, tightly reseal all containers. Store the product on a raised surface off the floor during cold weather and avoid storing near outside walls or doors.
