Paint feels tacky - What am I missing?
Lakersfan:
Hi folks,
I'm converting an old Sunset Riders cab into a MAME cab. The wood is pressed wood. I cleaned the heck out of it and sanded it until it was as smooth as a baby's behind. I primed twice and sanded between each coat. Now I am painting using Black Behr Premium Plus paint with a high density foam roller. After giving the first coat, it still felt tacky after about 5 hours, but in my anxiousness, I went ahead and sanded (without any problems) and gave another coat. Now, I've done 4 coats this way, waiting approximately 8-10 hours between coats but still feeling the tackiness. There's no problem when sanding but for some reason the tackiness feel just won't go away after painting and I can "scuff" the paint really easy by rubbing my fingernail along it. This last time I haven't painted since yesterday afternoon and it still has a tackiness feeling to it.
Will this go away? I feel like it's looking good but I am missing something. Can I get the buffer out and give this a coat of something to protect it? Maybe the weather has something to do with it (90-100 degrees) while painting in the garage??
Thanks for the help, you guys are the best!!

that's the problem right there
I am going thru this NOW on one side of my cab
Paint wants a ROUGH surface to stick to... You do NOT want to smooth your primer coats... at all... 100 grit at most... I did my cab SMOOTH after primer coats, and that was a MISTAKE. Anyway I found out later (a guy from the paint store told me) and the solution is to sand down what comes off and let the surface be a bit rough (not damaged, but not smooth either) and just paint on top of that... the paint will be thick enough to cover the "roughness" and it will stick to the surface much better.
I am no expert, as you see I just ran into the same issue, but I thought I'd pass the tips along.
Now my cab is looking and feeling a lot better. I believe you can sand LIGHTLY using 1500 grit after the paint coats ... to smooth a bit. Not the primer / before painting.
Good luck

make that 120 or 150 ... smooth-ish but not mirror-smooth for paint to stick
i confirmed with my father in law :) he knows his stuff

Give it a day to dry in a good temp (say 80 degrees or so). I've seen some issues where the paint didn't want to stick to the primer. If you take some water and rub it on a test spot on the cabinet and see if the paint comes off. If the paint comes off... yuck.
WunderCade:
I think what the guy is trying to say though, is that it remains tacky, as if not drying all the way.
That's a different problem than simply peeling of a smoothed surface isn't it? Unless the dryness of the paint would be affected by the smooth surface, but that doesn't sound right. The paint should dry whether or not it adheres to surface.
I know, having used a latex enamel paint, that stuff takes almost a month to harden just right. Are you using latex enamel by any chance?
