small blister repairs

[jimmy wise]

My hull has small blisters on the bottom rear. They are through two layers of gel coat. They pop open when ground through. How do you fix them

How do you fix them

That depends on how good you want your boat to look and how much time and money you want to spend on it.

My concerns.....do I take it to glass and fair in? Do I sand it tell they stop opening and fair

Re: small blister repairs

The only real fix is to remove all of the gel coat and the laminate down to a level where there are no more blisters on all surfaces below the water line. After that you rebuild the surface with epoxy and glass, then fair and paint. It's a very involved and costlyprocess

Post a pic so we can see how bad they are.

Id love to but everytime I try a banner ad blocks the window and takes over my phone. They are bad when you grind them down to glass they are pinholes. I think water caused them. They are all around or 3/16 in diameter

What's a little more money lol. I'm in six gallons of resin and no deck yet. The blisters stop St gelcoat

Re: small blister repairs

If your hull is blistered then using polyester resin and gel coat isn't a good option, it would most likely be a temporary fix.

Without pics it makes it very difficult to recommend any good methods.

I dont even know what 2 layers of gel looks like ..

Grind/fill with PB, Sand fair, apply gelcoat .. sand and buff.

Unless you want to do a bottom epoxy coating.

At that point its a little more "involved".

YD.

Re: small blister repairs

If the blisters are confined to one small location a spot repair may be OK, if they are distributed around the hull spot repairs are worthless.
