Chemical stone finishing Detail Information

Chemical stone finishing :  The texture and appearance of natural stone can be changed by applying chemicals to its surface thus creating a chemical finish. This type of finishing can be combined with other types of stone treatment and can be used on tiles that are already made and even installed.

Chemical stone finishing Details

Chemical stone finishing :  Finishing is a manufacturing process whose purpose is to obtain a surface with adequate characteristics for the particular application of the product being manufactured. This includes but is not limited to the cosmetic product. In some cases, the finishing process can have the additional purpose of getting the product to meet dimensional specifications.

Chemical stone finishing : There are four main sub-categories in this group: 

  • Acid wash
  • Epoxy treated
  • Meshed
  • Protective treatment

Chemical stone finishing : Acid wash

acids can be used to simply clean the surface of natural stone or to change its appearance, depending on the type of acid and the length of its application. Acid wash is an alternative way to achieve antiqued look and it also can have similar results as the water finishing. The good news is it can be applied retrospectively, meaning that you can change the look of an already installed countertop, for example.

Chemical stone finishing : Epoxy treated

it is a multi-step method that combines several techniques. First the stone is honed so that it has a smooth surface to which the resin can be applied. Then it is dried in a special oven and the process of applying resin and drying is done one more time. At the end, the stone is polished. The process improves the visual characteristics and the resistance of the stone tiles.

Chemical stone finishing : Meshed 

this is mainly an additional step to make the stone stronger, used mostly for defective marble or stone slabs. During the epoxy treatment of the stone a thin net of fiberglass or plastic is applied to the back side of the tile. It has no decorative functions.

Chemical stone finishing : Protective treatment

this is not an actual surface finishing, but rather the final step to protect the stone tiles by applying oil-repellents or anti-graffiti treating substances. In a nutshell, this is the process of protecting already installed tiles by treating them with the respective substance.

Types of Surface Textures stones

Rock or stone is a natural substance, a solid aggregate of one or more minerals or mineraloids. For example, granite, a common rock, is a combination of the minerals quartz, feldspar and biotite. The Earth’s outer solid layer, the lithosphere, is made of rock.

Rock has been used by mankind throughout history. The minerals and metals found in rocks have been essential to human civilisation.

Three major groups of rocks are defined: igneous, sedimentary, and metamorphic. The scientific study of rocks is called petrology, which is an essential component of geology.

Stones have different surface textures:

  1. Honed
  2. Polished
  3. Flamed
  4. Tumbled
  5. Sand Blasted
  6. Sawn
  7. Bush Hammered

Honed Surface Textures stones

It is produced by grinding a surface with high grit material to a uniform specification, without producing a reflective surface. Honed stone colours are not as vibrant as polished stones. A smooth finish with a slight sheen is produced by using a polishing head. This surface is very smooth, but often very porous.

Rubbing is achieved by a process similar to polishing abrasion, but without the resultant shine. Large production machines are also called polishing trains, and these are equipped with multiple heads that mount different abrasive grain per head and rotate on fixed benches along the process chain.

For small areas, this can be performed manually by means of articulated arm polishers. These achieve flat, smooth surfaces, dull and without any visible mark, provided the tone is darker than other terminal, highlighting the structure, texture and colours of the stone. This process is often applied to polished stones that do not reach the necessary degree of crystallization, often in the case of limestone and sandstone.

We could say that rubbing down is the first step to achieving brightness. This finish is applied in compact rock, with a minimum degree of hardness. As the polishing is achieved by abrasion, and in these cases it is most common to use conventional abrasives such as silicon carbide.

It is a finish that makes the surface of natural stone smooth and matted, without or with limited reflection of light. The same method and abrasive materials are used to achieve this finish as in polished finish, but polishing stops at an earlier stage and the stone is not buffed. The surface has a lighter shade but the overall colour and depth of the stone are preserved. Tiles are smooth but quite porous and should definitely be sealed. For our clients we offer travertine tiles that are honed and filled. In general, this type of finish can be applied to different stones and is preferred for locations with heavy traffic, such as floors, stairs, thresholds. We offer a great variety of honed tiles both for interior and exterior purposes – marble, slate, limestone, travertine, granite.
