Marine Epoxy FAQs:
How to use marine epoxy
Marine grade epoxy is an excellent way to protect your watercraft to ensure it can withstand the forces of rough seas. If you want to apply waterproof epoxy to your boat, follow these steps:
- Clean: Begin by cleaning your boat and removing any salt, grease, grime, wax, and oil using a de-wax solvent.
- Prepare: Once you’ve cleaned your boat, begin preparing your marine epoxy resin with a marine epoxy hardener. Do this by slowly pouring both into a bucket or plastic container while mixing. Once both are combined, pour your epoxy solution into another bucket or plastic container to remove any clumps and air bubbles. However, do not mix all of your marine epoxy resin and epoxy hardener at once. If you do, it will cure before you finish. Instead, make small batches and mix as you go.
- Apply: After you’ve mixed your boat epoxy solution, it’s time to seal the surface of your boat. Do this by using a paintbrush or a brush roller to apply the first coat. When applying multiple coats, know that AeroMarine’s 300/21 epoxy resin takes 12 hours to cure at 70 degrees Fahrenheit. It’s advised to apply between 2 and 3 coats of waterproof epoxy.
- Removing Excess Epoxy: Epoxying your boat can be a messy job. If you need to remove any uncured epoxy, use a metal or plastic scraper and scrape away any epoxy you don’t need. Then, use acetone or alcohol and scrub away the remnants. If the epoxy has cured, you can use a heat gun and scrape away any epoxy. Then, you can use sandpaper and sand away any excess.
Is marine epoxy waterproof?
Yes, marine epoxy is waterproof. Marine epoxy resin is a clear, low viscosity cycloaliphatic epoxy system that bonds well, is a strong and durable material, and provides a glassy finish that will make your vessel shine. Waterproof epoxy can be used to laminate boats using fiberglass, carbon fiber, or Kevlar cloth and to build stitch and glue boats. Underwater epoxy can bond to wood, metal, plastic, and other common materials, and can even cure underwater after it has been applied.
Is marine epoxy food safe?
AeroMarine offers non-blushing epoxies (300/21 and 400/21) which should not leave a residue that could contaminate food. These epoxies are used for bar tops, tables, and water tanks all the time. We would not recommend using these epoxies to create eating vehicles and utensils however.
