After painting my ceiling five times I finally found the paint that is extremely black ,flat as all get out and leaves no roller marks. The rollermarks were the killer for me. No matter what I did I could not eliminate them with any other paint. The company Rose Brand has it .
Honestly, if you are looking for the best paint for this purpose don't waste your time. It is a little more expensive but the Rosco Supersaturated velour is the way to go.
