Hi Michael – What problems have you had with painted surfaces? If you use regular cement/concrete paint, then yes you can have problems. You need to use an epoxy (I’m digging in my notes to get the name of what I’ve used successfully.) Bare concrete generates WAY too much dust for collections storage areas in my opinion. Properly cured epoxy paint wears well, is easy to clean and looks “neat and tidy”. Would love to hear what paints you’ve used and the problems you’ve had.
