Gelcoat curing

[damo]

Gelcoat won't cure properly if exposed to the air and remains tacky, so wax-in-styrene is added to make it into flowcoat. What if some wally forgot to add the wax? /forums/images/graemlins/blush.gif

How deep does the "tackiness" go? Is it possible to abrade it to a hard cured surface?

(And as an aside: if the item is kept in an oxygen-free atmosphere would that have the same effect, in terms of curing, as adding wax?)

I think you are talking acetone and removal of the gelcoat then redoing it unfortunatly but someone may know a better solution hopefully.

Just paint it with some flow coat with MW added.

I'd prefer not to use up any more of my dwindling stock if I could avoid it /forums/images/graemlins/smile.gif

You can put cling film over it to keep the air out and it should then harden . If its two pack and you forgot the hardener then it dries eventually but its no good and needs sanding off ..

The tackiness is only on the surface, it will scrape or sand off no prob.

Thanks James - the PVA spray trick is good to know (doesn't the operator make a mess though!)

How's Bideford these days? - I was a cabinet maker there for a few years /forums/images/graemlins/smile.gif
