## Overview

TotalBoat Aluminum Boat Barrier Coat is a high-build, two-component epoxy primer designed specifically for aluminum hulls and pontoon boats. Offering superior corrosion protection both above and below the waterline, it dries quickly without requiring sanding between coats. This waterproof, matte gray coating covers approximately 225 sq. ft. per gallon and can be overcoated with various bottom paints, making it an essential protective solution for outdoor marine use.

## 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: Application - 5 step process, lot's of labor, #1. sand boat, #2. JB Weld (Marine Grade) any pock holes, #3. Sand boat again, then use the recommended etching spray, #4. apply 2 part barrier paint 3:1 mix rolls on thick not like paint 3 coats minimum are recommended, last step #5. apply Aluminum AF paint... Well worth the end result with maximum protection, 3 quarts yields 3 coat's on a 14' boat...expect about 2 days to apply with day time temperatures being considered, read all instructions carefully, very detailed wear appropriate clothing and read entire procedures... Very impressive 👍😎
Review: Welder’s worst nightmare - Just got off the phone with my guy whos welding aluminum. “Jesus guy, what kind of primer you use on this!? I had to sand and torch it 3 times to get it off!” Gave me a good laugh. This stuff is pretty tough. Application was easy as long as you take your time and prep it correctly. Pretty happy and If i decide to totally restore another flat bottom in the future(NOT likely) I will be sure to purchase again.
