## Overview

TotalBoat Aluminum Boat Barrier Coat is a high-build, two-component epoxy primer designed specifically for aluminum hulls and pontoons. It offers superior corrosion protection by creating a waterproof barrier that adheres strongly without sanding between coats. Fast drying and easy to apply, it supports all 1- and 2-part marine paints and covers approximately 225 sq. ft. per gallon. Made in the USA, this gray semi-gloss primer is the professional’s choice for durable, long-lasting underwater metal protection.

## 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.

Review: Good product and service - The order, a one gallon, two pack epoxy based boat paint arrived quickly and was in much better condition than some previous orders I have places. Good communication and no problems at all. This is a very thick paint and has to be applied by sticking to the instructions.
Review: Sailboat Rigger Recommended - We had our pontoon boat out of the water to refurbish it. I sent photos of our electric motor shaft to my nephew who is a sailboat rigger for advice. It was looking corroded. He recommended cleaning the corrosion off and buying this particular product for protection. It is like a thick paint and was super easy to apply. For sure it will give our motor years more of service. Worth the cost.

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
