Finishing plasterboard to plaster joints

[Curquhart83]

Hi, I was looking for some help regarding taping the joints in a plasterboard wall. I've recently bought an old house and I'm planning on removing the lath and plaster on all of the outside walls of the property, insulating between the straps and then sheeting using insulation backed plasterboard (in order to preserve my cornice) due to cost I am planning to Ames tape the walls, however I'm not sure how to proceed with the corners where the plasterboard meets the old skimmed plaster walls. Would I just tape the corners the same as if both walls were plasterboarded? I'm a bit unsure about the adhesion to the plastered walls of the joint cement? Im going to finish the walls in 1400 lining paper then paint. Any guidance or advice would be greatly appreciated. Cheers

Yes just tape the internal corners, just as you would do if both surfaces were plasterboard. Adhesion will not be a problem.

Thanks for clearing that up Prenticeboysofderry, also would I get away with just using decorators caulk where the plasterboard meets the cornice?
