Sticky Gloss Coat.............What are my options??

It was going so well, then I seem to have tripped at the final hurdle.

Did the first coat in the morning, ok, then did the other side in the afternoon (mistake, too hot) so now I have a sticky board.

Any ideas what to do to solve this please? Can I strip it back, my paper is clogging badly and I am wasting heaps of the stuff. Is there a quick solution to remove the stickiness?

Thanks...........

Sticky gloss coats are a polishers worst nightmare.  Lots of things can cause a sticky polyester gloss, high temps, over 95 degress, and I wont even try, or not enough surfacing agent being the main culprets, along with wrong catylization ratios.  Oh yeah there are more, but someone else can add to the list.  Bad glosses are a great way to alienate yourself in a production setting.  Polishers take a bad rap in glass shops, they get no love and usually are treated the worst, but often its the glossers fault.  Most of the good glossers I have known work when no one is around at night; because  of less dust, and commotion, and even ambient humidity is a bit more congenial.  

Hey you can always leave it out as a modern “no pest strip;” any one else remember those?

epoxy or polyester?

you can sand it back, which is probably your best bet now. If at forst you hit it and it gums…Scotchbrite and re-gloss right over the top of the old. But since you started you probably have some nasty gummy uneven swirls that would give you a wavy second coat.

Good Luck

Polyester.............

Resin looses its tack in a lack of air.

Stick it in a vacuum bag for an hour, and see what happens

all true!

Most common text from the glosser…“What time you guys leaving”?

This is a little laborious but it works…you can shoot a super hot, hot coat and then sand the whole thing back down to prep for a new gloss coat. It doesn’t sound like you’re a production guy so I’d take the time to do this and start fresh.

Thanks for the input guys. I am most certainly not a production guy, this was my fifth board after a 33 year lay-off...so it took some getting used to after such a long break. The heat has been an issue over here in France, my mistake being trying to do the gloss coat in the afternoon, should have waited 'til the following morning. Over eager, I guess. I considered the extra hot coat and re-sand but in the end just got into it and sanded back best I could. Polished it up and the results are acceptable but not perfect. Board is a bit heavy, so could have used less gloss resin. Note to self: next board, speed finish and not gloss. And not dark blue!!!! Thanks again.
