painted latex over oil paint -- please help

15 years ago

I painted acrylic latex paint (SW Super Paint) over oil based paint on our trim following recommendations found here and from contractor friends. I cleaned the surface, sanded with 150 grit sandpaper, spackled then spot primed any dings, then painted two coats of the latex.

It has been about 2 or 3 weeks since I painted. I can chip off the paint with my fingernail. Is this normal?

I am in the middle of prepping the next room to paint latex over oil. Would like to hear suggestions before I proceed with all that work! Should I follow the same procedure but also prime?
