Oilbased Paint
how to prepare walls for painting if cracked d/t latex over oilbased paint?
I have the same problem due to the previous owner of my home. What a mess!. I was told I have to scrape off the big flakes and then sand off the rest. It takes forever to sand it off. I sure can empathize with you!
