## 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: Great product. Superior strength over poly based resin. - Great product. Learned about epoxy based resin and polyester resin on Youtube. Glad I found that info and I purchased Total Boat Epoxy to repair two snowmobiles. Both hoods one a simple crack and the other pretty much a big mess with multiple cracks and problems including a body with a torn out front hinge. On that I glassed in a couple layers of woven glass on the inside of a messy fiberglass tear after trimming it up a little. It's a vintage 70's sled with a fiberglass body. Duct tape was used as a soft form on the outside and it looks just great. Nearly zero transition between the epoxy and existing gelcoat. The repair feels as strong as the original if not slightly stiffer than the other side. I have yet to run it and see if the repair will hold. My prep work was very careful. Degreasing and lightly air sanding with a 2 inch 3M disc to expose fresh material to adhere to. Masking tape makes great dams and protects surrounding hardware I found. I am confident these repairs will last and I don't think I could say that if I were using a polyester based resin. I did pop the left over cured resin out of the mix cup and tried to break it. I could on the thinner cured part, but it was clear it was a pretty strong material. I ordered the fast cure and in a heated shop at 70 degrees it took a long time to cure I thought. Just about two hours. And I am reading that that is normal at that temp. I am however very used to automotive products cure times which is much quicker as in minutes. No hurry with this stuff unless it's very warm out. Wear your PPE as this stuff has a strong odor till it cures. And it sticks to everything. Gloves and disposable brushes are a must. Overall the product was great to work with. I see many other applications for this product. I have only used fiberglass products a couple times before. So an amateur I am. Good stuff. Great strength. Easy to work with. I measured and did not use the dispensers. So I cannot comment on those. 5 stars

## 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.
