Know Your Paint

I finally finished??the kitchen. It is??all painted and it??is beautiful. It??came out just like we wanted. Then I??found out that it was??oil paint underneath the latex I had just painted. I had sanded most surfaces, but when it gets wet, the paint just peels right off. It is very disappointing. I fear that most of it will have to be stripped or scraped off and then primed, and then repainted. After hours and hours of painting, I will have to start all over again. Sigh…
