We are removing semi-gloss painted popcorn texture from the ceiling. We have found the easy and cleanest method is to first float (put) all purpose lightweight joint compound #3 on the ceiling and let it dry over night. Then the next day use a joint knife spatula and start scraping it off. It should come off in large chunks very easy and very little dust.I hope this suggestion helps you. Let me know how it does. Good Luck.
