I have a vaulted ceiling in my living room with a popcorn texture. I decided to take it down. It has all come off very easily but not sure what I should do now. I was thinking that I could just smooth all the joints with the putty knife and then paint over with a good primer and then white ceiling paint. Do all the joints have to be perfect? I know there are some minor imperfections with the mudding that was done but the popcorn masked all of that. I tend to think they only used one coat of mud so not sure if I really should put a second coat of mud over the joints before I paint.

Any good advice is well appreciated. Thank you,
Greg
