Surface finishing

Sanded: for outdoor use, the purpose of sanding is to remove saw marks. Sand dry / wet with (SiC) carborundum, diamond discs or related abrasives.

Honed: under water spraying through series of sanding heads, application recommended for interior flooring, designation as follows:
C30 = very coarse clear grinding and sawing marks, stone color and structure almost invisible.
C60 = coarse, clearly visible grinding marks, color and structure barely visible.
C90 = medium, grinding marks visible from above, coarse structures visible, pale color.
C120 = medium, visible grinding marks, pale color, structure visible, grinding marks visible in grazing light.
C180 = a clear distinction from previous grinding, now feels smoother.
C220 = fine grinding, colors and structure easily recognizable, grinding marks still visible in grazing light.
C320 = silk matt surface grinding marks in grazing light still visible.
C400 = silk matt, biotit already shiny, grinding marks still visible in grazing light.
C600 = almost polished, minimal surface, grinding marks still visible in grazing light.
C800 = depending on the material, one can speak of polishing here, very small grinding marks can still be seen in grazing light.

Polished: grinding by machine with an even finer grain than with C800, with polishing the shades take on their different nuances, the colors are strengthened, the stone gets a reflective surface with a high gloss, not every stone can be polished depending on present minerals and structure of the stone. The veins and cracks are exposed in some species.

Flamed: the surface of the stone is dm.v. a flame (acetylene + oxygen) is strongly heated. Due to the sudden expansion of the material in the top layer, it breaks loose from the underlying layer. This creates a rough surface. In some cases, water is added under high pressure during the flames. The end effect is that the surface becomes rough but still feels smoother than with only flames.

Brushed: with cabon brushes the sharp edges are removed after flames. The brushes are soaked in a binder with (SiC) caroborundum / diamond grains.

Sandblasted + Brushed: the surface is first sanded, stopped and ground, then sandblasted and brushed.

Rustic: the corners and sides of tile are slightly rounded.

Versailles: surface tile sanded and brushed, serrated edges.

Castle: surface is aged rustically by combination of sanding, milling, brushing.
