Once the brick work of building a house is complete and want to cover the brickwork in plaster to paint a different colour. what that kind of plasster called?
also if you're building on a slope, how do you make the brick work level?
It isn't plaster, it is usually render, which is a mix of soft sand and cement powder. Older buildings have lime render on them. Plaster has no cement in it.
The second question is presumably a joke one. In case it is not, you dig the foundations deeper at one end than the other, setting the concrete to be level, then build the wall level onto that.
