I am intending to build a small house with "plaster bricks". However, my dream is to create a smooth "off-shutter" appeal to the exterior walls. The problem is while everything and anything is possible, this off-shutter impression may be prone to sucking rain water and damage the walls latter in the life of the building. My challenge therefore is two-fold:
1. How can I have the best plaster mix to achive this dream?
2. What can I do to ensure the plastered wall repels almost all the water when it rains?
I love the look of raw concrete but feels it will be uneconomical to trully concrete this small house.
