layer thickness on the concrete and the brick is less than 5 mm, on a grid or shingle to 10 mm.
applied to the rendering trowel.
rough surface is obtained, which does not require alignment.

Blot layer of spray necessary after curing, but still wet layer.Determined open hand, applied to the rough surface.Surface hard enough, but moist at the same time.
primer solution more thick solution for the rendering, well smeared spatula.In the middle of the Falcon
