Since the ceilings don't look too good after scraping the popcorn off it was recommended to me to trowel on compound to the ceiling to hide the imperfections. Is this necessary or is spraying an orange peel texture on ok? Should I prime before doing this? After? At all?
I plan of spraying an orange peel texture on the walls. The walls seem dirty and yellowed enough for priming. Should I prime them before or after the texture?
