Info & Guides
Why Should I Etch My Aluminum Boat Before Priming and Painting?
Getting primer or paint to stick to aluminum is very difficult, and it's a tedious process that typically entails sanding with very coarse sandpaper or blasting down to shiny, bright metal followed by priming with a specialty primer. The zinc chromate primers commonly used in the past are expensive, and less widely available now due to environmental restrictions. It's also not good for painting underwater metals, because zinc is the stuff of sacrificial anodes!
You can certainly still get excellent results with primer and paint, but the secret lies in etching the surface with the right product. Compare TotalBoat Aluminum Etch Wash to Alodine or Alumiprep 33. Our phosphoric acid-based etching wash is easy to use and works fast to create the toothed surface required for epoxy primer or paint to bond effectively and durably.
IMPORTANT: For best results coating aluminum, if using TotalBoat Aluminum Boat Etch Wash during surface prep, dry the surface completely and apply Aluminum Boat Barrier Coat within 1 hour after metal preparation.
Mixing Note: Combine base and activator components in a 3:1 ratio. If you want to mix the entire contents of both cans, just dump the can of curing agent into the can of base. There's enough room in the larger can to hold all the content of both components. Mix thoroughly, then induct for 15 minutes prior to reduction (if needed) and application.
Application Note: If applying antifouling paint over Aluminum Boat Barrier Coat epoxy primer, apply antifoulant while the primer is tacky to the touch. Do the thumbprint test—touch the barrier coat with your thumb. If the primer doesn't stick to your thumb, but you can make a thumbprint, you are within the overcoat window for applying antifouling paint. If you can't leave a thumbprint, you've missed the overcoat window. Sand with 80-grit sandpaper or apply another coat of Aluminum Boat Barrier Coat. Use the thumbprint method again before applying antifouling bottom paint.

I've used the barrier coat for fiberglass boats. This seems the same to me. Works good, builds up quick. Gets super hard. I used it on a 32' pontoon boat. Had to use 2 gallons.

Buy the Thinner Too!

The quart I got was extremely thick after it was mixed. Also, the solvent in the paint evaporates so quickly that it is almost impossible to lay the product down smoothly. This was while painting in the shade on a 70 degree day. The can I got definitely needs to be thinned to make is useable. I've ordered the 200 thinner and will try it again, after I sand off most of what I've already put down. Ugggh. It does cover real well!

It went on great. I like the way it turned out. It is going to be nice bullet proof layer. I did not add brushing paint thinner. I wish I would have added a little paint thinner just so the paint wasn't so thick while working with it.

Stuff is awesome. Unfortunately I couldn't cover the boat and had to paint in direct sun. My fault but didn't expect it to dry as quickly. Had my wife tipping it after I rolled it but the epoxy started to cure and started to clump. Not an issue but paint on an overcast day or thin. Went on smooth and there is probably no other paint as good as this. Would give it a 5 if it cured a bit slower.

This product is exactly what I was looking for as a barrier coat on an 28' aluminum boat. Applied the product per the directions and the primer has excellent adhesion, cured well and sanded well when I had to apply bottom paint at the location of the boat stands.

My aluminum canoe was in need of paint job, first I power washed to remove all loose paint particles, sanded some rough areas and used some BJ Weld to tighten up some of the leaks. Mixed up the TotalBoat Aluminum barrier coat primer (3 to1), it all fit in the quart can, mix well. Used a foam 4"" hot dog roller and rolled out the canoe hull. Let dry overnight then applied Total Boat Aluminum Finish Coat (Army Green). A week later took the canoe out into nearby lake and beaver ponds - thus dragging the canoe over logs through weedy areas. After I got home and inspected the hull, it was as if I just painted the hull - no paint scratches or scars. Paint provided excellent protection and proved to have outstanding adhesion.

Anyone with experience in two part poly primers would be hard pressed to find one that compares to Total Boat Aluminum Barrier Coat. I have been using this product to restore a 1963 Lone Star aluminum boat and am impressed with it's ease of use, coverage, and most of all its adhesion properties. This stuff sticks to aluminum like the military grade epoxies I used during my time in the Coast Guard. As long as you prep your surfaces properly, you can't go wrong. Wear a respirator when applying, as it is quite potent. A standard 3/8 nap roller does the trick, just burn off the loose nap prior to applying. Thanks for a great product Jamestown!

This is a wonderful barrier coat primer that reminds me of the Mare Island Systems Epoxy Polyamide we used in the military. Easy to apply by roller, (don't use foam rollers though, it will destroy them), and lays down smooth. A gallon goes a long way if you only mix it in small batches. You will need to stir your parts for quite some time prior to mixing for best result. Use this in a well ventilated area, and wear respiratory protection as it is quite powerful from a fume perspective. This was my first experience with Total Boat and I am more than happy with the result. I would highly recommend this primer to anybody who is doing an aluminum boat restoration project.

Q: I am applying this to my bare aluminum boat sides and bottom, just want to make sure it is ok to coat with Rustoluem Farm and Implement Enamel paint. And you have to paint within the 3 hour window correct?
6 months ago1 Answer
A: Hey Andy, Thank you for reaching out. The 3 hour window is only for Bottom paints for topside paints like the Rustoleum it would be the instructions for topside paints here: TotalBoat barrier coat can be used as a great foundation for topside paints and coatings other than antifouling paints. For these coatings, it is very important to allow the TotalProtect to cure enough to be sanded (24 hours @ 50ºF, 16 hours @ 70ºF, or 12 hours @ 90ºF. Sand the TotalProtect smooth to the required grit for the coating. Remove any sanding residue and apply paint.

Q: Can the product be used on aluminum stern drives where the original finish has corroded off? Can it be used over the existing original finish? What is the refinish process?
a year ago1 Answer
A: Hi there. Yes, this product can be used on aluminum stern drives, but it generally cannot be applied over most existing finishes. You will need to remove the original finish and blast or sand the surface to bright, shiny metal. Make sure all dust is removed, then clean with TotalBoat Dewaxer and Surface Prep. Although not required, TotalBoat Aluminum Etch Wash improves the bond and can be applied before using the barrier coat. Once the surface is clean and dry, apply the first coat of Aluminum Boat Barrier Coat within one hour of surface prep to prevent the metal from oxidizing. Remember that this is not meant to be a top coat, so you will need to apply an appropriate paint over the barrier coat. For more info, please contact us at 800-497-0010.

Q: Hello, what is the permeability rating on this barrier coat and how long should it be replaced? Thanks
3 years ago1 Answer
A: I reviewed tech sheets from several brands and none of them offer permeability ratings. I am not sure if there is an industry standard for such a measurement. Generally, it is considered a permanent solution and manufacturers make no recommendations for recoating. It is common for boats to build up enough layers of bottom paint over time that it may be necessary to remove the paint by sanding or blasting with a medium such as ground walnut shells. This would also remove some of the barrier coat so it would be necessary to apply some additional coats to buil up back to the recommended mil thickness.

Q: Hi I'm painting a 41 foot 14 foot beam aluminum haul for the Gulf of Mexico and inland up river from Mobile Alabama. I'm painting by myself and want your input on both barrie coat mixing batch size pot/life and roller life/time. How many coats if it was your only home. Then what's your best antifouling paint how many coats do I need. I really would like to get 5 years. I'm a live abroad retired. I want to do this the right way. How many gallons of each would you really buy. I'm in Demopolis Alabama at Kingfisher Bay Marina 100 miles from nowhere so you tell me how to do it.
4 years ago1 Answer
A: You will find detailed application information with answers to most of your questions on the technical data sheet located under the ""Data Sheets"" tab below the product description. How large your batch is will be totally dependent on the environmental condtions at the time of application and the tools you use. refer to the tech sheet for more details. The mohair roller supplied with total protect should survive for one coat. Foam rollers like the ARW Mighty Mini will lay down a smoother coat but they will fall apart. It took me three rollers to get through one coat on a 20' powerboat. One gallon of Total protect will cover @225 sq ft and you should do 3 to 5 coats, depending on the type of roller you use. You will need to use a multi-season copper-free bottom paint such as Pettit Hydrocoat ECO or Interlux Micron CF. Bottom paints typically cover @400 sq ft per gallon. After barrier coating, apply 2 coats of bottom paint for the first season then one additional coat for each extra season. To leave the boat in for 5 years, you will have to apply a toatl of 6 coats of bottom paint.
