Make emergency repairs without hauling out

Discovering your floor hatches floating to the tune of your shrieking high-water alarm can wreck a relaxing trip in a heartbeat. When bad things happen on a boat, they can happen really fast, requiring immediate action to reverse the situation, or at least keep it at bay. The more time you spend on your boat, the greater the chances are that some day you’ll be faced with a disaster that threatens your boat’s ability to stay afloat.

Prepare yourself with an emergency toolkit that includes TotalBoat Underwater Repair Epoxy. It lets you make repairs without hauling out first because it can be applied underwater to patch, fill, and seal leaks in aluminum, fiberglass, wood, and steel hulls.

Mix it, apply it, and cure it underwater—even underway

When we say underwater, we mean underwater—for mixing the two components, applying the putty, and letting it cure. Of course, it works just as well in air above the waterline, too. Either way, it’s easy to mix—just wet your gloved hands, grab equal-sized chunks of Part A and Part B, and combine thoroughly. Mix as much as you think you’ll be able to use in 30 minutes. Keep the putty wet while mixing it. This isn’t hard to do if you’re underwater, but if you’re working with it out of water, the second you feel it sticking to your gloves while mixing, wet your gloves and keep mixing. The putty is ready to use when it becomes a consistent, dark green color.

In an emergency, our Underwater Epoxy Putty gives you a generous working time of up to 30 minutes at 70°F, which gives you enough time to slap it on the repair area, smooth it out, mix more, apply, and smooth, to build up a thickness of 1/8" to 1/4". It’ll begin firming up in about 2 hours at 70°F, and is super-sticky enough to stay where you stick it, and will cure properly, even while your boat is moving through the water returning to a safe harbor.

Rock-hard, reliable repairs on everything from boat hulls to pier supports—and much more

This versatile epoxy repair putty cures completely hard in 6 hours at 70°F—in air or underwater. It creates a high-strength, extremely hard surface that protects against impacts and abrasion, making it ideal for repairs to hulls, docks, pilings, sea walls, buoys, concrete barriers, and many other wood, steel, aluminum, fiberglass, and concrete structures. While it’s protecting repaired surfaces from impact damage and water intrusion, it’s also preventing new corrosion on metals and further deterioration on concrete and wood.
