Product Details

TotalBoat 5:1 Epoxy Kits include everything you need to tackle marine epoxy repairs and fiberglass projects. The five part resin to one part hardener ratio is considered the 'traditional' marine epoxy system of choice for projects like bonding, coating, fairing, filleting, and laminating.

Complete project-ready epoxy kits includes: TotalBoat 5:1 epoxy resin; your choice of either fast or slow TotalBoat hardener; calibrated epoxy pumps that dispense the right ratio of resin and hardener, 2 stir sticks, and 2 mixing pails.

System Group Sizes: A - Quart Kit; B - Gallon Kit; C - 4.5 Gallon Kit.

Note: Don't need the pumps, stir sticks or mixing cups? Gallon size kits are also available with just resin & hardener included. This 'no frills' version makes sense if you just need more epoxy.

Info & Guides
TotalBoat Traditional 5:1 Resin mixed with TotalBoat Fast or Slow Hardeners cures to an amber color, and is not suitable for clear-coating applications. It is the ideal marine epoxy system for boat building (especially fiberglass) and common composite repairs.

For clear-coating applications, or where an ultra clear cure is important, we recommend TotalBoat High Performance 2:1 Epoxy. TotalBoat Crystal Clear 3:1 Epoxy may also be used for such applications.

For extra long pot life and working time, use TotalBoat Tropical Epoxy.

Tip: Wash cured epoxy with water, scrubbing lightly with a Scotch-Brite pad to remove any amine blush prior to over=coating or painting.

Important Safety Information

Always wear protective clothing and equipment to protect your eyes, skin, and lungs when working with TotalBoat Traditional Epoxy Resin and Hardeners. Personal protective clothing should include appropriate gloves, safety glasses or goggles, a proper respirator, and a proper apron or similar protective clothing.

WARNING: The TotalBoat 5:1 Epoxy Slow Hardener can expose you to chemicals including bisphenol A, which is known to the State of California to cause female reproductive toxicity. For more information, go to www.P65Warnings.ca.gov

Excellent results
By Gill from Eden UT

Verified Purchase

I really appreciated the pumps. Took guess work out of measuring and the inconvenience out of pouring.

Bottom Line Yes, I would recommend to a friend

Excellent product
By Weaver from Harvey Cedars NJ

Verified Purchase

The fast hardener is just that, really fast. You've got 15 minutes at best. If the resin is thickened with wood powder or silica, I recommend spreading it out on a piece of cardboard to disparate the heat and give you extra time.

Bottom Line Yes, I would recommend to a friend

Epoxy Great. Pumps and Plastic Jugs, Not So Much
By Big Boat from US

Verified Purchase

Epoxy is great. My resin pump has been miserable to use since day one (hard to pump and it drains back into the jug). Also, plastic jugs? That's plain stupid. The other epoxy setup I have going, from the other guys (you know who), has a pump that works and metal jugs. Do that.

Bottom Line Yes, I would recommend to a friend

Worked Well.
By Chuck from Arkansas

Verified Purchase

Learned about Total Boat on the Boatworks Today YouTube channel. Purchased it to repair a 6 inch diameter soft spot in the deck of my Catalina 22. It mixed easily. Total Boat silica was added to thicken the mixture. The thickened mixture was injected using a syringe into the soft spot through holes drilled into the deck gel coat. The mixture filled the cavity left by the deteriorated wood core. Within 24 hours, the deck was solid. It worked wonderfully.

Bottom Line Yes, I would recommend to a friend
