: I'm restoring a patuxent 19.5 that I built about 10 years ago. Previously
: I've used MAS and West Systems products with good results. This time I'm
: using TAP marine epoxy. So I mix up a batch with graphite powder mixed in
: and coat the bottom. It's about 60 degrees, and the instructions say
: that's OK - barely. Come back the next morning and it's still wet. What?
: So I turn on the furnace to 80 and go away. 10 hours later it's still wet.
: I go to TAP website and they say that it shouldn't be applied below 77
: degrees! Nice! So I try another coat in a pre-warmed shop with a little
: extra hardener. Same results!

About all you can do is scrap it off and try again with a different resin.

I suspect it won't be any fun scraping it off, not much else you can do. Might have to sand the surface afterwards too so you don't get interaction between the different resins.

: I call TAP, and they suggest another coat using the quick set catalist. I do
: so, and get a few patches of firm set, and most is still wet! At this
: point I'm disgusted and set the kayak on a rack for a week.

: It's still wet! What should I do (besides never get within ten feet of TAP
: epoxy ever again.)
