When the word “polish” is mentioned, especially in the context whereby marble is concerned, the first image which comes to many people’s minds will be the shiny and glossy surfaces which literally take up all characteristics of a mirror. However, not many people realised that polish, is just the many ways of marble finish. Other types of finish include honed, which is more subtle and not as reflective compared to polish, or antiqued, which incorporates both modern and vintage designs so as to evolve an elegant feel.
Nevertheless, there lies a twin tower in marble polishing, the wet and dry. In dry polish, special-made silicone-carbide sandpapers are used. These circular sandpapers come with grit, which delicately cut away the top layer of the marble, so as to remove any scratches or unevenness visually visible, leaving behind only an even level.
Dry polishing is a challenging task as dust particles are created during the process, therefore, it cannot be performed in enclosed area and professionals performing the job will also need to be garnered by face and eye masks. Besides, there is a need to keep a constant momentum during sanding, so that all areas are equally even. Furthermore, the grit will also need to be turned up in a gradual manner, so that it is not easy to leave behind unwanted scratch as a result of over polished.
As a result of such hassle, it is recommended to start dry polishing, from one piece of marble first, compare the before and after result with the marble next in the line, before moving onto the next and so on. On top of sandpaper, there is also the option of using diamond polish, which induces finer polish, as it contains 3000 grits.
On the other hand, water is used in wet polishing, which minimises the discomfort created by fine dust in dry polishing. Furthermore, as water lessens the fiction between marble and polish, the end product will also have a relatively longer life. However, one needs to understand that the colour or appearance of the marble may change, immediately after wet polishing and after the marble is dried thoroughly. Hence, it is recommended to engage in professionals to complete the job so that such difference can be ideally reduced.
Occasionally, wet polishing also includes the use of chemicals for removal of etch. Unlike dullness, which is accumulated over time, etch is caused by the spilling of accidental acids, such as household detergents or orange juice etc.
Regardless of the kind of polish, both of which served the same purpose, that is to return old marbles, their new lives.
