## Description

TotalBoat 5:1 Epoxy Resin Kits contain the traditional 5:1 marine grade epoxy resin and hardener valued for its high strength and waterproof cure. This premium epoxy kit is perfect for completing a variety of boat building and repair projects for wood or fiberglass boats. Kits contain TotalBoat Traditional 5:1 Epoxy Resin, your choice of TotalBoat 5:1 Fast or 5:1 Slow Hardener, plus calibrated 5:1 resin and hardener pumps designed to dispense the exact mix ratio by volume, and a perfect cure every time. The 5:1 epoxy resin and hardener components may be mixed by weight or volume. Choose TotalBoat 5:1 Fast Hardener when working in cooler temperatures (50-85 Degree F). At 75 Degree F, pot life is 12 minutes. Slow Hardener is best when working in warmer temperatures (70-95 degrees), or if you want to extend working and cure times. At 75 Degree F, pot life is 20 minutes. For dispensing product via pumps, the recommended temperature is 60-70 Degree F. TotalBoat 5:1 epoxy resin system can be applied to fiberglass, reinforcement fabrics, wood, etched aluminum and bare steel. This versatile, total boat epoxy resin system can also be combined with TotalBoat fillers to make a strong adhesive, filleting material or fairing compound. Available in 3 sizes: quart, gallon, and 4.5 gallon kits. Quart kit includes 30 fl. oz. of epoxy and 6 fl. oz. of hardener. Epoxy Gallon kit includes 127 fl oz of resin with 25 fl oz of hardener. 4.5 gallon kit includes 4.5 gallons of epoxy and 1 gallon of hardener. Apply by brush, roller or syringe.

All TotalBoat products provide great value and great results. 100percent made in the USA.

Review: I had to replace / rebuild some rotten deck and part of a stringer on my '93 Maxum 1800. After much product research, I decided to try the TotalBoat Epoxy 5:1 kit with the fast hardener. I have used almost three gallons via three different orders.I have had no issues and great results with each. When I started, I used a scale to ensure the pumps were measuring the correct amount - they were within a gram or two every pump of both parts, thus ensuring proper mixture. I am comfortable enough with the pumps' calibration that I no longer use a scale and every batch sets up fine. Working in the heat, I would only use five or six pumps of each, work it, then start another batch. That ensured it did not set up before I could get it where I needed it. With cooler temperatures, I had more time. Adding fillers for fillets is no problem. I like that it comes with the calibrated pumps, two mixing bowls, stir sticks and gloves, though the gloves are pretty thin. Everything you need is in the box on arrival. Since it is an epoxy resin, it does not stink like the polyester resins common at local big-box hardware stores. Though the product is not necessarily cheap, it is much less expensive than some of the more popular brands on the market, and those do not include all the extras. This is a quality product and good value. The shipping was very fast. I'm 100% satisfied with both the product and the seller.

## Questions & Answers

**Q: Is this a no blush epoxy?**
A: Unknown

**Q: Is this polyester resin**
A: No it is not polyester resin.  It is epoxy with a 5 to 1 ratio, and cures extremely hard.  Polyester should not be used on a repair below the water line.  Epoxy will not allow water to absorb into the repaired area.

**Q: can I use this to fix lamination on my RV side walls**
A: Worked great for me rebuilding the wall sandwich (fiberglass, thin ply, foam board,,,) after water delamination.

**Q: Can you do inside of bathtub with this?**
A: Good Afternoon, this product cures to a high strength, water resistant finish, so using within a bathtub should be fine. Thank you.

First off, do not, I repeat do not use the mixing cups that come with this set more than once. I used each cup 3 times. And on the third use, the resin melted the cups, and even got so hot it was smoking. Had to throw it in a puddle and pour more water over. It had the water boiling. Now, going backa couple of weeks......I used this for the first time last night. I'm very impressed so far. A lot easier than trying to use the bondo brand and guess the amount of hardener. Word of warning. Once mixed, you have maybe 10 minutes before it starts to jell. And if you're wearing latex gloves, you'll be able to tell because it gets hot. And I mean hot. Also, the thinner you spread it, the faster it sets. Had some pool up on the boat bottom and an hour later it was still tacky. Highly recommend!
