It is the brick without any processing, just as it comes out from the mold and later from the wood oven. This kind of finish identifies the part of sandblasted brick: slightly rough and natural. It’s the oldest and traditional finish. In this case, using release agent (silt) is really important both for grain (finer or coarser) and color. We can offer different kind of RAW finishes to meet the esthetic and functional customer needs. This finish is recommended for flooring outdoor because it is naturally non-slip (as reported by CERTIMAC in the website), for the walls (stone walls, column cladding, external thresholds / stairways and attics) or for who love the authenticity of real handmade brick. Your good taste combined with our wisdom will be the best partnership for the brick choice.
