Popcorn Ceiling - paint & primer?
I'm in the process of painting Kilz primer on our nasty popcorn ceiling (there was icky discoloration from age...and then I went & left a burner on & smoked the place up last month, hence the Kilz). It's so much better and brighter than it was!
My question is, do I need to topcoat the Kilz with actual ceiling paint? If so, why? It's not like I'll be scrubbing the popcorn. Will it chalk off even if it's not touched? Thanks!
