If you want to apply latex paint over oil paint you have to first prepare the surface by sanding, cleaning with detergent, and coating it with a primer. The primer can be oil or latex, but in either case it should labeled as a “bonding primer.”

The same is true for applying oil over latex. However, latex paints are more flexible than oil and many modern formulas are just as tough as oil, so it may be best to simply stick with latex for the new topcoat.

1. Hi!
My contractor painted my walls and moldings with latex satin paint over existing oil based satin. The walls are fine but the doors and wood works are starting to peel. What do I (he) do now? He can’t seem to come up with a constructive solution other than apply another coat. I don’t think that’ll help. What do you suggest???
Thanks

2. My painter painted my room wall with oil paint n now I want to scrape it for another emulsion paint,how do I go about it pls?Thank you

3. I painted latex over oil on the exterior on my French doors’ however I am not sure if because they are fiberglass is the reason I have not had a problem. We did not do anything to the surface before.
