Hi fellas

As you can see from previous posts did a basic part time college platerin course just to improve diy skills. One job i have ahead of me now is to plasterboard a ceiling (only small toliet) and skim the side walls as the plaster is pretty good already. My question is what do i do to make the join between the ceiling  pplasterboardand the wall seemless. Do i use a tape to join the gap of the ceiling board to the wall before plastering it all?? If so what is the plaster tape called???  


thanks in advance

Paul
