Looking for advice. I have applied gel coat to a hatch cover which hasn’t cured. It had too much pigment applied when mixing and I stupidly continued. Went off in about 10 mins so thought all is good. After a week I can brush my hand across it but is still tacky... so not so good. Do I need to remove it? If so, how do I do this?

You can remove uncured gelcoat with acetone.  Whats the hatch made of? Gelcoat wont cure if it's on epoxy with amine blush, the gelcoat must be cured,  & washed with soap and water first.

There is nothing, absolutely nothing, half so much worth doing, as simply messing about in boats

Was it waxed or unwaxed Gelcoat?

If it was waxed, with too much pigment then you'll have to remove it.

If it was unwaxed GC, stick another coat over it with right amount of pigment with styrene/wax.

Last coat should always have wax. Except in female mold.

 

Safest way is to remove & start again.

 

With brushing GC, I always use unwaxed & multiple coats, with wax in the last 

for cut & polish.

And, too thicker gelcoat tends to spider crack.

Thanks.  It was waxed GC brushed over old GC that I had sanded back.  Looks like removal is needed - You live and learn!
