I'm jumping in on this late, so forgive me if I'm off track ..I just saw the
reference to 404/414 Barrier Kote from Interlux, my favorite primer, and it
looks like there's some controversy on what it is. The reason that it's
called Epoxy Barrier Kote is because some coatings, paint that is, get
unhappy with leftover amines and what not on cured epoxy. To paint the
epoxy with such a paint, alkyd enamels for example, you need to sand, wash,
and prime the epoxy with an appropriate barrier coat that sticks well to
epoxy and provides a good substrate that he paint also sticks well to. The
Interlux 404/414 Barrier Kote (stinky but good) makes a very good primer for
protecting paints from epoxy chemistry that might still be on the boat, and
it's very high body (hides defects) and sands well too. Like I said, stinky
but good. Keep the doors open.

Just for the record, Jim, the can is labeled Epoxy Barrier-Kote. And the
catalog describes is as suitable for above or below water applications.
The directions also state that it must be thinned.

Thanks for your thoughts.

Interlux 404/414 is not a barrier coat. It's a sandable primer whose
function is to provide a tie coat between sime substrate and an
impervious
finish coat such as an LPU paint. If applied as directed, it's just
loaded
with expensive solvents and is consequently pretty porous. Useless under
bottom paint. If you are using it as a primer under finish paint and
not
under bottom paint, go for it. I'd try acetone. Let us know your
result.

Can I successfully use acetone to thin epoxy barrier coats? I am
thinking
of
Interlux 404/414 in particular, but the question is also a general one.

I am aware that there are proprietary products for this application, but
I
need to paint tomorrow morning, and the nearest dealer is about 60 miles
away.
