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

I was very satisfied with the Epoxy Kit.
By Ray from Brainerd, MN

Verified Purchase

I used the epoxy to fabricate a new centerboard for a Lido 14 sailboat. This was my first experience with using epoxy to adhere 5/8" wide strips of mahogany to 13" wide board. This included using a hardener in the resin. It was stressful but the end product looks great.

Bottom Line Yes, I would recommend to a friend

Great for my teardrop
By Tanner from Colorado

Verified Purchase

If you follow the steps exactly the kit is very user friendly. The fast resin cures very well here in Colorado spring weather, even with 40° temperature swings. Sands easily and takes paint well if you mar it with 220 grit. Great resin kit, thanks!

Bottom Line Yes, I would recommend to a friend
