10 Techniques for marble processing

Marble is one of the most widely used precious stones in construction. The typical shiny surface, the veining and the delicacy of the coloring tones make marble, together with granite, the ideal material for covering surfaces in sophisticated and elegant environments, for artistic purposes and for internal and external architectural elements.

As beautiful as it is delicate: marble is particularly susceptible to the aggression of chemical and atmospheric agents, which deteriorate its surface causing it to lose its shine, to the point of undermining its natural splendor.

In maintenance activities, one often finds oneself in front of floors, sculptures and worn coatings, but with a charm and aesthetic value still intact.

The interventions for the recovery of marble objects are of different nature and depend on its consistency, its state of preservation and the problem that has been found.


A process suitable for interiors, through the use of automatic machines that polish the surface with the abrasive action of grits, large or particularly fine depending on the surface to be treated. Allows the floor to recover brilliance, eliminating degradation and porosity. In outdoor it is not very effective for the simple fact that due to the acid rain the results would last a short time.


Suitable for both indoors and outdoors, as the polished surface resists acid rain without being noticeably dented. This treatment gives the marble a satin appearance, which is not reflected and is not reflected.


It is used to give marble an antique and worked appearance, generating an orange peel surface through special grinding wheels in plastic-abrasive material. Particularly suitable for outdoor use, for structures that you want to give an “aged” look.


Creates a slightly corrugated surface, giving an appearance similar to the untreated natural material. In addition to aesthetic purposes, it is performed (with machines that beat with spikes on the surface of the object) to give the floors its anti-slip properties. Not all marbles can withstand the impact of this process.


Used for the processing and maintenance of the facades of old building facades, the flaming through a thermal shock – it is in fact performed with very high-temperature hydrogen torches, 2500-3000°- gives the marble a natural brushed split appearance, very nice to see.


It serves to scratch the surface, giving a particular aspect appreciated both in the internal walls and on the external floors, given the non-slip characteristics of this work. The toothed rolling machine, rotating at high speed on the surface, gives more or less marked and deep lines.


The marble is immersed in an acid tank to obtain an appearance similar to brushing, but even more vintage and aged, especially if the object was treated with bush-hammering or sandblasting before acid-etching.


A special shot blast machine shoots the marble with a powerful jet of compressed air-air and sand, to give it a particularly marked satin finish. Given the power of the jet, not all marbles can be treated in this way, certainly not those that are too soft or with excessive holes.


It gives the marble a worn look. With this process, small blocks of marble are handled, given the very high costs. After tumbling, the object can be treated with special paints to restore its shine.


Processing that can be performed either by hand or in the factory with special machines. It gives a very rustic appearance, generally used for window sills and other external architectural elements. By trimming it is also possible to impress characteristic drawings on the plate. Not very economical, perhaps, but certainly effective.
