It presents a fine rough appearance, without original colour alteration and achieving greater defense of atmospheric chemical alteration.

It is a heat treatment obtained by applying high temperatures (higher at 2800 degrees cent.) on the stone.

Being rough, it is non-slip and it is also especially suitable for outdoor use because its treatment provides greater defense to atmospheric chemical alteration.

The treated surface presents uniformity, with a series of peaks and valleys, similar to those obtained with the bush hammered.

Sandblast is achieved by projecting the surface of the stone with silica sand or corundum, driven at high speed and variable air pressure, through a nozzle. When using blast made of steel, this finish is called Blasting. Depending on the pressure applied and the flow rate of the abrasive, a finer or thicker finish is achieved.

It is non-slip and resistant, very suitable for exterior coatings.

The stone is treated with metal or diamond barbed brushes so that, by friction, the surface turns out to be glossy.

A rough but glossy surface is obtained, with a soft touch, as the surface peaks are very rounded. It has a velvety look

It is recommended to be used on flooring for both indoor and outdoor use, although, in this in case, its degree of slip has to be checked. In interior pavements there are no difficulties significant for cleaning.

Considerably smooth and flat surface.

It is treated when cutting slabs, steel strapping looms, which are used to cut granite blocks.

The stone has a light and matte tone indicating its natural origin.

Smooth and matte finish. Highlight texture and colours more than other dull finishes and leave no marks of any kind

By abrasion, with rotary heads. It could be considered a step prior to polishing, since its surface is simi-lar, but does not show shine

It brings compactness and hardness to the surface and although it is smooth it is not as sliding as po-lishing.

Very smooth and minimal porosity. Widely highlights the brightness and colour of the material with a darker appearance than in other surface treatments without any scratches appearing.

Through abrasion with rotating heads of decreasing devastation that gradually polish the stone until the minimum degree of porosity or closed pore is reached.

Being closed pore, it is the cleanest finish and the least absorbing liquids, making it more difficult to stain against external aggressions especially water, oil, acids, etc. resistant, but its absence of porosity and relief make it less non-slip.
