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

Great product
By Mark from Beaufort NC

Verified Purchase

used to repair soft/waterlogged deck. Worked great with coosa board and it's strong. Ran out near the end and bought cheap epoxy. The difference is that the Total Boat was slightly thicker and it makes a difference. Used West system in the past... couldn't tell the difference except that total boat is less expensive. use it.

Bottom Line Yes, I would recommend to a friend

Worked Great
By Rookie boat refurbisher in MN from Minnesota

Verified Purchase

This was my first experience using a 2 part epoxy. Generally, everything went well with the application. Since this was my first time it was hard to tell when the epoxy was fully cured because the surface remained tacky. I waited 48+ hours with my first pour because of the tacky residue. After I wiped it off, I discovered that it was just a residue so I only waited 24 hours for my next pour to cure and it worked perfectly. The only real complaint that I have is that the resin was so thick that when I used the supplied pump the bottle would crush. I ended up holding the bottle by the handle and then pushing down on the pump. This worked but was not ideal. I was mixing and applying at temperatures between 55 and 40 so that probably contributed to my difficulty with the pump. This project was for a transom replacement on a '92 Crestliner Sportfish 170.

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
