Marble renovation
The renovation allows a refurbishment of a marble floor.
The first operation is a wet grinding. This method is identical to that of marble marble workshop with diamond abrasives of different particle sizes. Scratches, impacts, scratches, stains are eliminated by removing a thin surface layer of the stone.
Two finishes are most often encountered: Honed or polished polishing.
The gloss-polished is achieved mechanically by sanding with an added polish.
The sweetened offer a smooth finish to the touch. It offers a contemporary and natural. With a water repellent treatment is a smart choice for the scene of intense passages.
The most commonly encountered marbles under the floors: Carrara White, Pink Portugal, travertine, Botticcino, Perlato of Sicily, Savoy Blue, Red Verona, Comblanchien, Granito (Terrazzo), Green Alpine
The mosaic floors can be refurbished using the same principle. .
Marble Grinding
In the case of laying a new pavement, the rough grinding is inevitable to perfectly level the connection of the tiles together and the joints. Also the thickness of the slabs may be slightly different (because it is not a perfectly calibrated industrial product but a natural product
The water in marble sanding is preferred because it significantly reduces the amount of dust, which can work in the apartments, the climbs stairs of condominiums, shops and others.
Once the draft phase carried out, the operations are identical to those required for the renovation.
French production of stones hit bottom in 2014
Over 60 million euros of revenue lost between 2013 and 2014 (and 2015 should not be better), the French natural stone industry continued to dive. All industries are concerned with significant declines in activity between - 8% - 22% and unfortunately many stops activity.

Enamelled lava
The density of the dish (2.3) is to be considered for the design of supports and desks for handling as a plate of 1 m2 in 20 mm thick weighs almost 50 kg!
This is a great difference of sandstone that weighs him that 18 kg per m2.
Finishing panels: rectangular, round ... can be obtained by cutting the plate with diamond saws or water jet before enamelling. Large surfaces can be obtained by juxtaposition of plates. In practice, most manufacturers are limited in the size of the panels they can be glazed by the size of their ovens. The stone can be engraved shallowly before enamelling and exposed stone surfaces can be etched sandblasted. Surface edges that will not be in a sealing can be "dropped" (weakest angle, more exposed to vandalism).
For fasteners in the covers and guards, the plates may be:
• pasted on walls,
• either on the surface like tile, then it may be prudent to drop the edges plate development,
• is embedded in a reserve provided on masonry, a slab, a plaster or a rock.
• stuck on a wooden stand furniture or metal with an epoxy adhesive; a metal casing that surrounds the sides of the plate is a conservative fixing against vandalism; a seal silicone around 2 to 3 mm or below, is essential to compensate for expansion of the metal.
• held by small metal claws, which may become the weak point of the whole.

Stone splitting machines
All the stone cannot be polished. But all the stone can be splitted.
But every stone, every product, every processing need the proper splitting machine. It is not a problem because the machine range available on the market is large.
Once the necessary power decided, the useful dimension, the productivity required it is easily possible to work on the good spilitting machine choice.
To help there is a very good book "Stone Splitting" written by Piero Primavori and published by mec 38050 Scurelle, TN, Italy. This e-mail address is being protected from spambots. You need JavaScript enabled to view it
