I scraped the popcorn from the ceiling in my den. It had a nice knockdown look. When I tried to roll the primer, Zinser 1-2-3, the remaining texture started to come off on the roller. I only rolled about 20% of the room and then quit. The ceiling looked worse than when I started. After the primer dried, I scraped it and the texture underneath off down to the sheetrock. Then I went to plan B. I went and bought a Wagner paint crew plus and and sprayed the primer. This worked great. My plan now is to let the 1-2-3 sit for a week and adhere to the sheetrock. Then I will spray texture on the ceiling, probably the whole ceiling so it will blend. Then roll 2 coats of BM. Does this sound reasonable? Will I have any problems with paint adhering to the ceiling (not the roller) or cracking?
