Epoxy Barrier Coat over Gel Coat?
 
I have read that in order for an older hull to dry out sufficiently you must remove the gel coat and let it dry out before applying an epoxy barrier coat and that it will not dry out without removing the gel coat. I also read of people putting an epoxy barrier coat over the gel coat. My questions are: Do you have to remove the gel coat in order for a wet hull to dry out? Is it acceptable to place an epoxy barrier coat over a dry hull? In my case my HR 35 is under a shed and will be there for 4-5 years during it's restoration. The hull has moisture. Will it be sufficiently dry after 4-5 years without removing the gel coat? Anybody with THE ANSWER? Thanks.

Blisters are a bit hit and miss in there occurrence on different boats and If you don't have them by now you probably wont have and issue and can re-coat the boat with what you fell best about after some research

Neither of my two J24s(1981s) or my current 1970 Cal has had any issue with them and yet sometimes almost New boats get them :confused:

If the laminate is wet, then you will probably have to remove the gelcoat. :) However, depending on where you're keeping the boat and how wet the hull is, you may not need to peel the gelcoat, especially considering how long it is going to be out of the water.

If you have a moisture meter, it would give you a good starting point to judge whether peeling is going t be necessary. MaineSail has a great post on Moisture Meters and how to use them.

Hi
Blisters you say , do you see them quite well ? are they side by side all over he hull ? if not , supposedly the gell coat is the protection for the fibreglass, unless blisters totally cover your hull i would not take it off
just the blister itself should be grinder out , until all the bad fiberglass is remove around the blister , isn't it the solution to get the blister out and dry the hull ?
that is my humble opinion

me again
also , someone read the moisture on your hull right ? is you hull full fibreglass or sandwich with , a core between fibreglass ?

if core is the building method , maybe it is the core that is wet if so I dont know are you can dry that core
