Morning all, I’m new here, you’ve all been recommended by a few friends. Just bought a house that needs a bit of work, including putting a retaining wall back in. I’m comfortable with all aspects bar the plastering so will get someone in to do that, I just need to know how much thickness of plaster to allow for. I’ve drawn up a floor plan, you can see the remains of the original wall, as you can see it butts up to the original location, and I don’t want to create a step along the wall. So, my question is, how thick will a plasterer apply plaster, and how much of a step should I leave between the plasterboard and the finish of the existing wall?? Thanks in advance!
