joints are always taped and mudded before applying popcorn.They usually just don't do as good of a finished job as would be needed for a flat ceiling
I really like using "hot mud" for repairs. By that, I just mean the powder you mix that has a time rating - like EasySand 45, which means it sets up in 45 minutes instead of having to air dry overnight.So, is it a good idea to just do the repair with DAP, then sand the whole ceiling, prime and paint?
or repair with drywall compound then sand, prime and paint?
any difference?
