Latex over Oil-based trim
Many years ago I painted the oil-based trim in my home that had yellowed and gotten dingy looking with latex. I cleaned, sanded, used a primer recommended by the paint store employee (forget the name) and then applied two coats of my trim paint. Everything looked great, and the paint never peeled off when I cleaned it.
Now I'm in a home where the previous owners applied latex paint over oil-based on the trim, and it's peeling up in many areas. Given some of the other "improvements" they made in this home, I'm fairly confident that they did not properly prepare the original oil-based trim to accept the latex paint.
I'm wanting to repaint it, and wonder if I can just use the previous method of clean, sand, primer, then new paint (I will be using Sherwin Williams Pro Classic). Will this work even with some areas peeling? (You can pull small sections up, and they seem a bit rubbery until they break.)
