I'm having trouble covering some plywood with fiberglass cloth. The problem
is that I want to be able to see the wood under the cloth, but the cloth
just doesn't seem to want to get "transparent". I've covered plywood before
using this method, including a wooden kayak, and it usually comes out great.
I've been able to sheath the foredeck of the boat successfully, and the
fiberglass "disappears" into the epoxy resin, but for some reason all of a
sudden I'm having problems. It gets about 90% transparent, but stays a
little milky. I've made sure that I lay the cloth onto a wet piece of
plywood, and that I force more epoxy into the weave, but still it looks only
partially transparent. Ideas?

Thanks,

send me a little piece of the cloth and I will try it with my epoxy on
some wood and send it back to you.
- that should provide some clues......

Paul, that's exactly what I did and I could rip the cloth right off the
wood. I also tried it with a piece of West Biax and could not rip it off
the wood so I suspected the cloth the problem. I threw the cloth away
and bought new cloth.
I'd love to send you a piece of the new cloth I have so I don't have to
do this again.
Thanks,
Dan

Time needed to get good adhesion is an unrelated issue more tied with
curing times. WEST epoxies seem to develop good adhesion within a day,
our epoxies need 2 days. But WEST has a shorter potlife and bigger
exotherm so I suspect it is further down the curing curve after 12 or 24
hours than our epoxy. Note that epoxies really take about a week for
full cure.

Again, I would be pleased to coat your cloth with our BASIC NO BLUSH and
send it back to you - send to 48 wildwood, pittsfield NH 03263
