Available in gray quart size, it covers approximately 225 sq. ft. per gallon and is made in the USA by boaters for boaters.

## Description

TotalBoat Aluminum Boat Barrier Coat two-part epoxy primer is the dependable way to prime aluminum in preparation for bottom paint or other 1- or 2-part paint finishes. It’s easy to use and adheres extremely well to properly prepared aluminum hulls and pontoons to create a waterproof tie-coat barrier that offers exceptional protection against corrosion. This effective high-build formula fills small surface imperfections and provides excellent adhesion so paint won’t peel and will last longer. In addition, you can apply it to all underwater metals for superior corrosion protection.Proper preparation is the key to success when priming or painting aluminum surfaces. We strongly recommend the use of our TotalBoat Aluminum Boat Etch Wash (sold separately) to clean, condition, and prepare the aluminum surface so it has enough tooth for the barrier coat primer to adhere to strongly and effectively. After rinsing it off thoroughly and drying the surface, apply Aluminum Boat Barrier Coat primer within 1 hour of metal preparation.Aluminum Boat Barrier Coat has a simple 3 to 1 mix ratio that’s easy to use, can be recoated with itself in as little as three hours at 90°F, and requires no sanding. After mixing thoroughly, allow an induction period of 15 minutes before reducing with TotalBoat Epoxy Primer Thinner 200, if needed, and applying by brush, roller, or spray equipment. Compare to Interlux Interprotect and Pettit Aluma Protect marine epoxy primers. Aluminum Boat Barrier Coat provides great protection at a better value for your money. All TotalBoat products are developed by boaters for boaters, to provide great value and great results. We know what works and what doesn't. 100% made in the USA.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Buy this now
*by S***L on July 7, 2025*

1000% reccomend this. I bought this as a precaution to help stop any leaks that nay or may not happen. It popped up when I google waterproof barrier undercoat for a boat. This product is not rated to be waterproof I later found out but once I applied it I felt super happy it went on perfectly to my aluminum 16foot boat. I do reccomend getting a top coat for once it drys. Use inside as well if you can

### ⭐⭐⭐⭐⭐ A few things to keep in mind....
*by P***N on May 29, 2025*

What a great product, just a few things that helped me... It is going to be too thick out of the can. drill mixing attachment to mix the base and hardner together. Thin 10% with totalboat 200 thinner and roll it on with a bunch of small foam rollers. Wear a good respirator, probably too dangerous to spray without a full force fed suit as I have read these epoxies in aerosol can damage your lungs real bad, not worth the risk.. It etches and bonds to even lightly oxidized aluminum. I quit sanding and just washed clean and applied, seems to be holding up no differently than a lot of sanding...

### ⭐⭐⭐⭐⭐ Good stuff
*by W***Y on March 8, 2025*

Worked great, would recommend drill with mixing attachment. And wear gloves.
