  1. Quite helpful! there are places where sharp sand is not used in wall rendering. They use only the plastering sand.

  2. I tagged it sharp sand because I'm from southern Nigeria (Delta) and over here, when you buy sharp sand, you mix it with clay.
    However, we also have the mixmud which I think is the plastering sand you're referring to but in most cases, the mix mud develops cracks after a while and no body wants that at all
