Water tank fix (built in)

geoffr98 · #1 (**permalink**) 05-13-2007

In our boat we have water tanks build into our keels, over time the gelcoat has cracked so we are looking to repair it, however we are having a hard time finding any foodsafe gelcoat (or potable water tank safe). Is anybody here aware of such a product ?

Does anyone have any other suggestions ? (a flexible tank won't work as we have baffels which hold up the floor (as well as stop the water from sloshing).

thanks,

Ceram Kote is an FDA approved epoxy for use with potable water tanks. You can read a bit more about it here.

It is used in the fiberglass potable water tanks built into my boat.

Thanks - I have found two distributors that carry it here in Canada.

Sherwin-Williams also has an epoxy that goes on the same as paint. It is used to coat the interior of railroad potable water car. Don't remember the name, but it is a special order item. I found it on their web site.

NSP 120 - NSF 61 Potable water approved Epoxy Adduct

Is a NSF/FDA approved 'lining' epoxy for potable water tanks. Just roll it on.
Sold in 1+1 quart containers.
As with all such epoxies, use the 2-pot method of mixing to insure 'complete' mixing of the 2 parts.
