Paint getting tacky after dry?
Posted by TerryB on Wednesday, January 1, 2020 8:52 PM

Ok i have a delima here. I have had some paint jobs which were dry, polished and BMFed that got tacky as i was handeling them during the final construction phase. I have a dehydrator and leave most bodies in it for 3 days sometimes more and this has happened with all different kinds of paint.

My lastest project was painted with rustomleum laquer and dried for a week then decaled and weathered (lighty sanding threw decals and top coat to get to red primer) Then it was top coated with krylon chystal clear flat acrylic and let dry for almost month now as i continue to build it the more i touch itti the stickyier it gets not where it leaves finger prints but tacky.

Wats going on here?

Had the same problem with other acrylic (and non-lacquer) clear coats - Velejo & Gunze. Took months for the clear to fully cure. I stay away from them now and use lacquer clear.

I have had the same issue with Duplicolor clear lacquer a couple of times.

Generally, I have excellent luck with Duplicolor clear, but even the best will end up with a bad can occasionally.

Terry, I think that your problem may be that you are putting Acrylic paint over Lacquer which is an oil based paint. Acrylic basically forms a plastic airtight film when it dries. Enamels and lacquers on the other hand take a lot longer to dry out thouroughly despite feeling dry to the touch. The tackyness that you describe may be because the lacquer is trying to bleed out as it is not properly dry and trying to lift the acrylic. I use acrylics as primers and find them OK using lacquer or enamels as top coats.
