Sanding, which is also used to clean and maintain stone surfaces, is obtained by wet or dry fine siliceous sand blasting of the surface.

The treated surface will appear bleached, rough and grainy to the touch, and this type of machining will give the material a rustic, delicate and elegant appearance.

The texture will be rougher or coarser depending on the size of the sand granules used. This finishing can also be applied to materials that are less than 3 cm thick.
