I am painting a small bathroom with Sandstone paint that I bought in Lowe's (for non-US users, this is big chain of home improvement/remodeling stores).
The result is just terrible. First, it requires multiple passes just to hide the white base ($50/can, and I am finishing a second can. $100 just to paint a small bathroom is rather excessive). Second, I can't get the paint to lay uniformly on the wall: sand (the aggregate in the paint) ends up as big, visible build-ups on the wall.
What am I doing wrong and how do I do it right?
