I have on a friends boat. It is harder then normal paint to remove but a far cry from epoxy resin. With the resin I ended up using a belt sander and it was eating up 50 grit belts like candy.

Freesail99 I used blue tape when I was using epoxy on my bottom to show where I stopped or around the stands when I had to move them. It was simple and it worked for me. I still need to be shown how epoxy paint can offer the same protection as epoxy resin. I've removed paint and I've removed epoxy resin. The resin has to be 10 times harder to remove.

sailingdog If you look at a sodablasted hull, it has a very fine tooth to it, much like what a good sanding prep job would leave behind, Sodablasting is definitely the way to go, if you have to remove all of the paint and want to do it quickly and cost-effectively IMHO.


Have you popped any of those little blisters. If you haven't, you probably should, but do so wearing googles/safety glasses and gloves, since osmotic blisters are filled with nasty chemicals at relatively high pressures. If the blisters are dry, and not filled with liquid, it is more likely that they're small layup voids, since osmotic blisters would be wet. If they're not wet, just fill them with thickened epoxy and paint over them.

For barrier coating, I prefer to use Interprotect 2000E. The main reason I like using the IP2KE is ease of use and application. I've described my method for applying it, using the two different colors, white and grey, to make it as simple to apply as possible, especially when working around the boat stands on this site before. If either you or Barry want me to dig it up, I can repost the technique in this thread.

Freesail99 MAS Flag epoxy and the slow hardner is what I used.

sailingcal21 Thanks for sharing. Looks like the result that I ended up with except I have lots of little blisters about the size of a pencil eraser. What's your thinking on barrier coating? Straight epoxy or use products specific to barrier coating? I'm currently considering MAS epoxy and the slow hardner.

BarryL Hello,

The price seemed high to me, but I think it was worth if. It took the guy two solid days of work. The soda is very gentle on the hull. I looked at two boats that had been media blasted (small plastic beads) and the bottoms looked terrible. Many many places where the gelcoat was blasted off, leaving pockmarks in the fiberglass. On my boat about 1/2 of the previous barrier coat is intact, in other places gelcoat has been revealed. There is no damage to the gelcoat, it is nice and smooth.

I do plan on sanding everything, then washing, barrier coat, and bottom paint. I will use an ablative paint, so I never have to go through this again.

One last point, this is Long Island, NY, so EVERYTHING costs more. The sand / media blast guys charge $1200, and then you would have LOTS of time and money to properly prepare the bottom.

KeelHaulin If the surface appears rough; with highs and lows and generally porous, you should sand it smooth before putting down paint. The porous surface caused by "blasting" can cause further problems with blistering. Sand blasting is a definite no-no; don't know how soda blasting compares...

sailingdog Barry-

That sodablasting sounds a bit pricey... I had my boat done, yes all three hulls, last summer, and it was almost half of what you got nailed for.


In case you were serious... you can get the equipment here.

$1700??? How long did it take? Where can I buy me one of those soda blasters?
