Hull Blisters

Postby rwidman » Mon Mar 02, 2020 5:37 pm

When I bought my boat in 2008, the surveyor reported some blisters. He said they weren't serious.

Right now, the boat is out of the water to be bottom painted and the yard manager reported blisters. He gave me two options; scrape the gelcoat off and repair the blisters and barrier coat for $12K - $14K or just paint over them. I'm going to paint over them.

Anyone else have a blister issue and what did you do about it?

Same story when I bought, that there were a few blisters.

However, on one of my pull outs we took off a fair bit of the existing ablative and other paint and discovered many blisters.

We took the first option and had all the blisters taken out and refilled, sanded and then 2 epoxy barrier coats applied then ablative paint.

We were told we'd never see a blister again.

So far so good, boat comes out in 2 weeks so I'll see again how it is going.

The other advantage of this approach is that you have an extremely smooth bottom when done as all the old paint layers are gone.

Cost was $2,500 CDN.
