I am admittedly new to DIY and especially painting furniture, this being my first project. I put together a custom desk two months ago using a laminate IKEA countertop. I followed the instructions most often repeated for painting laminate pieces like this: first I cleaned and sanded the countertop, then went in with two coats of primer ("the red" Zinsser) and then three coats of paint (acrylic latex interior paint), sanding in-between each application of primer and paint and allowing 12 hours for the primer to dry and 6-12 hours for the paint, just depending on when I got around to painting.
As mentioned, it's been two months since then and the countertop is still tacky. It doesn't feel tacky when you touch it, but if I place anything on it for even 10 minutes there is a noticeable peel when I go to pick it up. I placed a stack of papers on the desk and two days later the bottom piece of paper was very stuck, so much so that small bits of paper tore away and were stuck onto the desk when I peeled it off.
Is two months not long enough for the paint to fully cure? Did I just use the wrong kind of paint? Am I safe to just put a topcoat/sealer on it now?
