So, I'm finishing my detached garage as a recording studio, and now that I'm back from the holiday break it's time for the next step: painting.
Since we built new partition walls to be our interior space, we have essentially a brand new space. As I start putting together my materials list, it occurs to me that of all the painting I've done, I don't think I've ever painted over freshly hung drywall. Are there any special concerns here? I assume the walls need to be cleaned before I start, since dust is all over them. What else? Is primer essential, or will the big box paint+primer in one work just as well? Any tips would be much appreciated here.
