Designed for marine and composite projects, it offers low viscosity for easy fiberglass wet-out, compatibility with fillers, and a durable, waterproof finish that resists chemicals and weather. Available with slow or fast hardeners, this all-in-one kit ensures flawless application and rock-hard cures for boat building, repairs, woodworking, and more. ## 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: READ THE INCLUDED INSTRUCTIONS!!!! THEY ARE PERFECTLY CLEAR ON HOW TO USE THIS PRODUCT CORRECTLY! - I have a 14' x 10' pop up camper roof that I am completely redoing (the old roof just decayed into nothing) with new wood and covered with a new fiberglass seamless shell. I still have about a 1/4 gallon left to begin applying to the next layer. Worked perfectly. Easy to mix and use. One full pump of the resin, one full pump of the hardener to get the perfect 5:1 ratio with no fuss, no muss every time. The instructions are SUPER CLEAR on this! The bold header at the top of the page is crystal clear! Anyone complaining that it is not clear apparently cannot comprehend what they read very well, or just plain cannot (or did not) read it. I was working on a day that was about 65-70 deg F (~50% humidity), and the working time was fantastic! I was able (with 2 other helpers) to get the entire 1 layer installed and bonded to the wood in less then 8 hours total. ## Features - High-Strength Marine Epoxy Resin Kits: System formulated for bonding, coating, and laminating.

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.

THEY ARE PERFECTLY CLEAR ON HOW TO USE THIS PRODUCT CORRECTLY! *by B***S on May 20, 2026* I have a 14' x 10' pop up camper roof that I am completely redoing (the old roof just decayed into nothing) with new wood and covered with a new fiberglass seamless shell.

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. ## Frequently Bought Together - TotalBoat 5:1 Marine Epoxy Resin Kit for Bonding, Filleting, Coating, and Laminating - Use for Fiberglass, Wood, Carbon Fiber, Boat Building, Repairs, Woodworking (Gallon, Slow Hardener, Pumps) - Fiberglass Roller Tools Kit, 3pcs Fiberglass Resin Laminating Bubble Roller Set for Tub Shower Bathtub Boat Repair - Fiberglass Cloth,6oz 50sq Feet E-Glass Plain Weave Glass Fiber Cloth,12 Feet*50 Inches Woven Fabric for Boat RC Plane Auto Surfboard Tub Pool Repair --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sn/products/13247904-totalboat-5-1-marine-epoxy-resin-kit-for-bonding-filleting](https://www.desertcart.sn/products/13247904-totalboat-5-1-marine-epoxy-resin-kit-for-bonding-filleting) --- *Product available on Desertcart Senegal* *Store origin: SN* *Last updated: 2026-07-14*
