Marble is a hard surface that is desired because of its shine and attractive colouring possibilities. However, like with any surface, a time will come when it loses its sparkle and appeal. When this time comes, a restoration process begins.
What is the process of marble restoration?
Marble restoration involves four steps:
Grinding involves the removal of scratches, rough patches, stains, and scuffs. It can also be referred to as flattening as it also provides the ability to even the marble surface, which may be uneven due to installation or settling. Grinding involves the use of a low-grit (30 – 50) polishing pad.
Honing involves a higher grit (100-200) polishing pad than used in grinding and removes deeper stains and scratches. Furthermore, it adds a smoother and shinier finish to the marble.
Polishing is an elevated grit of 400, 800 or 1500. This is used on flooring that does not need grinding or honing and is in pretty good condition already. By polishing, the shine is restored to the surface.
A fine grit polishing pad, around 3000, is used to add the finishing “glamour” to marble. It is also known as crystallisation. The buffing phase also involves a chemical treatment which allows the marble to have its glassy shine.
Sealing is the final step in marble restoration. It is recommended that a high-quality sealer is applied to marble at least once a year. By doing this, the life of the marble is extended. Additionally, the marble is protected from cracking and chipping.
When should I get my marble floors restored?
Generally, marble flooring polishing lasts from 1 – 3 years. However, it may be difficult to know when it is time to get the restoration done. When marble floors start losing their shine and this is not brought back through buffing, it may be time to consider having a restoration completed. You may also want to consider restoration when you notice stains, scuffs, chips or cracks.
Can marble be resurfaced?
In short, yes. Marble can be resurfaced after the top layer has been removed. This is achieved by grinding or sanding back the sealant layer to expose the underlying surface. Once that has been completed, the marble can be resurfaced, polished, or re-sealed.
