Our unrivalled expertise means that we are familiar with standard maintenance procedures and with the specialised techniques used to polish stone floors.

The marble restoration and maintenance process initially involves a deep clean with a combination of a rotary cleaning machines and ‘by hand’ cleaning in the hard-to-access areas. This is followed by using the latest technology diamond resurfacing through a graduated range of abrasive pads that slowly skim off the top surface of the marble. This process is commonly known as marble grinding or honing, and starts with a coarse grit pad that erases surface scratches, some stains, and other forms of surface damage.

We then progress through the finer grades, honing the fresh marble surface with a finer abrasive pad to create a perfectly smooth finish. At this stage, there is a sheen to the surface of the marble which can be left at this level and sealed or impregnated. If a deep polish finish is required, various polishing techniques can be used to achieve a mirror finish. It is this final marble polishing technique that quickly restores the original glossy appearance and enhances the natural colour to the marble.

Our Values

With a thorough and conscientious approach to work, we focus on quality and value throughout all of our specialist marble services. We strive for invisible repairs wherever possible.

Common problems and recommended treatments

Stun marks

Caused by sharp impact on the stone surface, ladies’ high heeled shoes are the most common cause of stun marks. These marks are sometimes very deep in the stone. Grinding with diamond abrasives can remove or improve some, but if not, replacement of the damaged stone is the only alternative. Deep scratches can usually be repaired by resurfacing with medium to coarse grit diamond abrasives.

Spalling

Spalling is a condition in which piece of stone has broken leaving a chip or hole in the face of the stone. These can be repaired by filling with a polyester, epoxy or cement based filler material coloured to match the stone. The affected area must be resurfaced after filling to level the filler material to the stone surface. Replacing the stones is another, but more costly, alternative.

Staining

In most cases, staining can be remedied by a process known as ‘poulticing’. The appropriate poultice for the stain is prepared and placed on the stain and allowed to dry. As it dries, it draws the stain out of the stone. If this method doesn’t work, ‘honing’ (grinding) the surface down to a fresh layer of stone and then re- polishing may be needed to remove the stain. 

Cracks

It may be possible to repair cracks by filling them with a suitable filler material. Very large cracks, or very small hairline cracks, cannot generally be filled and the only alternative is replacement.

Lippage

Lippage or uneven tiles must be ground down or beveled to alleviate the problem. This is done by grinding with coarse grit diamond or abrasive stones.

Etching

Etching is a dull area on a stone caused by spills of acidic products such as citrus juice, vinegar, soft drinks, etc. If the etching is very light, it can possibly be repaired by polishing the area with a polishing powder. Heavy etching must be repaired by resurfacing the area with diamond abrasives.
