I hope this is the right place to post this. I hired a contractor to do a tinted USG diamond finish skim coat over existing drywall. The job is unacceptable in terms of color and detail. Now I would like to hire a plasterer to repair/redo the job. My question is, assuming the bonding of what is there is OK - Can a skimcoat of USG Diamond finish be put over another or will I have to do another coat of bonding agent? If so will that work?. The skimcoat put on by the contractor is rough in places but hard and shiney in others.
Thanks in advance.
