Not as thick as some hey.
I have a brick wall that has been extended and is not straight. It has a bow in it of about 30 - 40 mm due to the extension. I want to plaster and tile the wall and would like to get it straight. Can it be plastered in the low area up to 40mm thick say down to about 10 mm at the ends of the wall? I thought maybe plaster in 2 goes and let the first one cure a bit before the final rendering.
