Why are my LEGO still sticky after I paint them? I use primer beforehand but the acrylic paint is still tacky hours after they're painted. Thanks!
I suspect that you used an acrylic paint with a solvent that softens ABS plastic.
Your bricks may take quite some time to harden.
It's possible they never will.

I sanded the brick and used primer but it's still sticky even though it's been drying for 3 hours so not sure what I'm doing wrong? – mario23 Apr 10 '20 at 19:17
Sticky paint is usually caused by painting over a coat that wasn't fully dry. If you did not wait several hours after applying primer, that would be the cause.
