Hi,
my staircase wall needs to be replastered. I'm sure its probably an inch thick or more (I have broken off a small piece to check). I will be getting a few quotes from plasterers.
I want to know what is the proper way to build up the wall back to the original depth ?
I've been told that hardwall plaster is the correct undercoat, but gypsum web site says it should only be applied to 11mm thickness.
Should two separate coats of undercoat be applied?
Or should an initial sand-cement (or other render) be applied and then the undercoat plaster ?
