In the case of the 404/414, the can is labeled in bold print "Epoxy
Barrier-Kote".

In the case of Interlux's Epiglass epoxy, the ad in Boaters World catalog
describes it as a two-part, high build primer suitable as a coating where
gelcoat has been removed. I called Boaters World and they assured me the ad
was written by Interlux. I called Interlux's tech line and they said that
was not an appropriate application and didn't understand why it was
described as such.

Neither organization seemed much concerned with correcting matters when I
pointed out it would be a good idea. Boaters World, however, did refund the
purchase price of the Epiglass even though it was partly used.

I'm curious ...I gave away my last bit of 404/414 so don't have a label to
read, but who's description was misleading? Interlux's? Or was the
description ambiguous instead? You know ...poorly written and could apply
equally well to more than one (conflicting) type of use? Have you called
the rep and told him about your experiences? Might save some newbies
headaches later on if the labels were clearer... Most companies won't want
you to be unhappy because a product was used for the wrong type of
application.

Thank you all for your comments.

For the record, I ended up thinning it about 20% with alcohol. This
worked well as far as thinning is concerned, but the alcohol apparently
evaporates too fast. It is impossible for the brush strokes to flow out
well. So -- more sanding. The good news is that it finds, and with
persistence, fills -- or at least coats -- about every pin hole in the
resin base. It dries quickly and appears to sand well. I am actually
using it as a primer under Interprotect 2000 BTW.

This is the second time I have purchased Interlux products which have
been described as applicable to things I later found out they were not
truly suitable for.

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.

It seems that it should be labeled "Barrier Coat for Epoxy".

A few things worth noting (I'm a marine and industrial epoxy vendor)...

no such thing as expensive solvents (relative to the epoxies) ----

All of our epoxy primers are essentially just solvent thinned epoxy. You
can add about 1 pint of solvent to 1 gal of resin (not including the
curing agent) before you begin to 'damage' the epoxy, but for many
applications no problem with using even a lot more solvent.

no problem with adding solvent to any sort of barrier coat epoxy.
Barrier coat epoxy is generally just industrial epoxy paint (resin plus
pigment plus a thixo agent). Regular marine epoxy will work too but will
probably drip and sag a good bit.
