## Overview

Featuring precision pumps for an exact 5:1 mix ratio and options for slow or fast hardeners, it offers customizable working times and cures to a durable, waterproof finish that resists chemicals, abrasion, and weather. Compatible with wood, fiberglass, metals, and fillers, this kit is the go-to solution for professionals and DIYers aiming for flawless marine and woodworking projects.

## Description

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.

Review: Superb wood filler - Rather than replacing more than a dozen rotted deck boards. I decided to try to fill the "ravines." I tried many wood putties: n'yet . Bondo? n'yet (Became unworkable too fast for my application). This kit with its slow hardening was perfect. Beyond being simple to use, with the two attached pumps pre-measuring the correct amounts of the resin and hardener. I decided to WILDLY experiment with "additives." First, I added a couple of scoops of Durham's Water Bingo! Mixed easily and perfectly increased the amount of the glop and was easy to spread into the ravines. Dried hard as a rock but it must be abraded hard for painting. Next, I stuffed steel wool into craters, which are deeper than ravines. Then I infused the steel wool with the mixed epoxy. Why? Epoxy bonds with steel and throws off heat to boot. The gaps I filled with steel wool and epoxy are clearly stronger than the original wood fibers because solid steel....Btw: you can perform microsurgery on the "treated" steel wool if you have a competent grinder with attachments. Finally, I mixed grout with sand into the epoxy. Why? Because the sand in this concoction, when used to fill shallower gaps, provided a surface onto which coating would better adhere. Success. Moral of the story: I would have been far, far better off, prying up the deck boards, purchasing new ones, and installing them. Why didn't I do it? I am a retired desk jockey and when I started the project more than a year ago, I did not have the carpentry skills to cut and replace the boards. I have them now. Absolutely no regrets even though the filled-in boards are less than cosmetically perfect. Two warnings: you should absolutely not experiments with epoxy additives. Use only those that the manufacturer prescribes. My outcomes were fine but yours may be disastrous. Second, I could care less about bubbles in the epoxy. Accordingly, my recommendations are expressly limited to the use to which I put the product.
Review: Easy to work with when you follow the mixing instructions - I am building a wooden boat and I chose to use the TotalBoat Epoxy Resin Kit (Gallon size, Slow Hardener) to fiberglass the wooden hull. This is a 5 part epoxy to 1 part hardener. The kit includes pumps for the epoxy and the hardener along with some disposable gloves and two mixing/graduated plastic cups. The cups have markings for several mixing ratios. I used the 5 to 1. Fill the cup up to the level you think you need and add the hardener up to the hardener line. Stir for at least one minute to 2 minutes and go to work. When it is properly mixed it will look clear as water. I have been pleased with the working time of the epoxy. If you are working in direct sun and/or hot weather, you may find that it starts to set/harden quicker. I am working outside in the shade and I have plenty of time to apply epoxy, fiberglass and more epoxy over the fiberglass before it even begins to harden...hardens overnight.

## 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.
