TotalBoat Traditional 5:1 epoxy resin is a versatile marine-grade system with greater tensile strength and durability in harsh environments compared to polyester resin. Use marine epoxy to bond, coat, fillet, fair, or laminate – few epoxy systems offer this level of versatility when it comes to fiberglass boat building and repair, industrial composite construction, or woodworking projects. Working with fiberglass? Its low viscosity and self-leveling properties make TotalBoat 5:1 resin ideal for wetting out fiberglass, for laminating, wood penetration, gelcoat blister repair, weather and waterproofing, and other marine applications.
Use TotalBoat 2-part epoxy resin kits to build, patch, and repair boats and watercraft, including canoes, kayaks, paddleboards, or surfboards. It’s also suitable for carpentry, RV delamination repairs, automotive repairs, and all kinds of composite fabrication. Blend this fiberglass epoxy resin with fillers and thickeners like microballoons, wood flour and silica to create filleting compounds, fairing compounds, and high-strength bonding adhesives. Compatible with concrete, stone, most metals, wood, and reinforcement fabrics, including fiberglass and carbon fiber. Cured epoxy can be sanded, shaped, and painted. Cured resin resists abrasion, impact damage, scratches, solvents, salt, and is 100% waterproof.
Choose Quart, Gallon, and 4.5 Gallon epoxy kits with your choice Slow or Fast Hardener. Slow hardener extends working & cure times in warmer conditions. Choose Fast hardener in colder temperatures or when max cure speed is desired. Each kit includes resin, hardener, and calibrated, color-coded pumps. It’s as simple as 1 pump of resin for 1 pump of hardener for an accurate 5:1 ratio and a perfect cure. Apply epoxy by brush, roller, syringe, or spreader. Compare TotalBoat 5:1 marine epoxy resin to West System 105 epoxy resin with 205 or 206 hardener, MAS epoxy, System 3 epoxy, and other marine fiberglass repair kits.

Good stuff
I have used many epoxy kits before but this was great. I got the kit with the pumpers and the cups as well as enough resin and hardener to the do the project. Really easy to use. Made a miserable job a pleasure.

Good quality product
Great price for a great product and seems to use less product than other name brands to do the same size repair

Great product
Nice and workable but definitely order more than you think you will need.

woks great !
So far so good. Good value and the pumps make it easy.

5 days waiting for it to harden – still sticky
First, I’ll discuss mix ratio – advertised as 5:1. That’s confusing, because the bottles say 2:1 — Here’s the answer: Each stroke of the plunger in the hardener bottle will dispense one “unit” of hardener. The plunger in the resin bottle is larger – it dispenses 2 1/2 times as much per stroke. So 2 strokes from the resin bottle is 5 units, while one stroke from the hardener is one unit — result: 5:1. Now to the performance issues I have: First, the hardener bottle is for “FAST” hardening, although the description on the Amazon posting shows and says “SLOW” hardener. I prefer FAST, so no complaint – but it doesn’t match the advertisement.I”m repairing the engine hatch on my boat, which has edge damage due to water intrusion into the plywood around the edges. I removed the old gelcoat and the rotted plywood, applied a coat of mixed “Total Boat” epoxy to both the original fiberglass edge of the hatch and to the surface of the replacement new 1/8″ marine plywood, which i had rough sanded to get good adhesion. I clamped the plywood against the original fiberglass edge using multiple clamps (see attached photos), and waited. The next step would be to cover the plywood strips with fiberglass cloth, then sand, add a fairing compound, smooth, and gelcoat. I haven’t gotten that far. After 4 days at 70 degrees, the epoxy was still tacky, so I heated the area with two space heaters, to accelerate the hardening. 30 minutes later, the resin started dripping out onto the table! Removed the heaters. Now it has been 5 days, and the epoxy has returned to the tacky stage. The overall repair of my hatch will require a lot more epoxy, since i will be replacing all of the original plywood in the rest of the hatch. That will require 4 layers of fiberglass cloth, so I bought two “Total Boat” epoxy kits — neither of them returnable. I’ve used a very small amount of the first kit. I cannot afford to wait a week or more between coats (assuming this stuff ever hardens) – so it’s going on the shelf and I’ll order a name brand replacement kit.

Worked well and product received on time.
Getting the two part epoxy with pumps made it easy to mix the proper amount of epoxy (12.3 fl oz) using the slow hardner to level the area under a toilet. It flowed well and judging from the reflections from the surface (essentially no distortion) provided a flat surface. It set up in the advretised 6 hours enough to allow trimming with a sharp knife to remove the minuscus at the edges – I used a pliable putty to make a dam to constrain the flow to the desired area. I did call the supplier with a question and the gentlemen that answered the phone knew his product and how it could work for my application.I was concerned at first about how I could mix the proper amount without a lot of waste. After a quick measurement of the large pump and calculating its volume, I realized it would take quite a few pumps full to get the volume I wanted. So I just used the fl oz scale printed on the mixing cup to determine when I had enough. I still have enough to mix a little over a pint for future applications.
worked great. –
as expected
this stuff is easy to work with and has plenty of pot life. i did the bottom of a wooden boat with a size roughly 24âx15â.i did that same area on the other side of the keel.the gallon size came up short but the matting i used was really think.i had no problem mixing 5 batches for each side. no dry or hard spots as the pot life was long enough to smooth it all out.
