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.
