Can you paint textured (popcorn) ceilings?

Well, I wish this question was a yes or no answer, but it depends on a few factors. In general, yes you can, assuming the surface that was textured was properly primed. However, if proper prep was not followed the textured may come off when the roller is used to apply the paint. A sprayer may be utilized, but the prep work is greatly increased to protect furniture, walls, trim and carpet. A case by case evaluation is always needed.
