It's plaster skim over a rendered breeze block wall. I've always used readymixed tile & grout before and like that type of product. I've actually used the quadrant before and will do so again as it gives a nice neat finish. We have a heavy duty German steel bath and movement hasn't been an issue in all the years we've had it.
Can't wait to try my tile cutter. Gone are the days of carbide hand saws, nibblers etc.
