Do not require Plastering Interlocking bricks are formulated with a smooth finish and texture. If you are utilizing interlocking bricks in the wall construction, there is no need of plastering the walls. Apply a thin layer of paint to give a smooth finish and elegant looks.

Hence the interiors are much cooler. http://www.txlsk.com/container-yard-pavement/
