Marble and stone repairs
Repairs of cracks, chips, unevenness, holes in travertine or marble/stone tile replacement are all part of PMAC’s floor restoration service.
Cracks in stone floors appear because of movement beneath the stone – in the sub-floor. We can repair cracks, but if there is still movement in the sub-floor they will reappear.
Fixing and replacement
We source, fix and replace stone to match existing floors. Loose stones should always be re-laid, as they will eventually crack and may cause damage to the surrounding floor. New stone can then be colour-enhanced to blend in with the existing floor.
Grinding and re-honing
Grinding is a process whereby the surface is aggressively sanded to remove large stocks of stone. This process is usually recommended when stone tiles are uneven.
Honing is the process of smoothing the stone with the use of abrasives, Honing is performed to remove scratches. Honing can leave a stone floor with very little shine, although, at high hones, some stones may acquire a satin like lustre.
Lippage removal from marble and stone floors
Lippage is the term given to uneven tiles that are set higher than one another. Grinding is recommended when lippage exceeds 1/8th of an inch or if a completely flat floor is needed. The method of removal is to grind the floor completely flat, re-hone, and then polish.
Etch mark removal from marble and stone floors
Etches are caused by the acid content in spills reacting with the calcium in stone. Acidic substances include wine, fruit juice, vinegar or harsh cleaning chemicals not intended for cleaning natural stone. This can show as roughness and remove the shine. Etches can only be removed by honing and polishing. The floor should then be sealed with an impregnator.
Colour enhancing marble and stone
Modern seals can be applied to enhance the colour of the stone. It is important to remember that these seals will also enhance stains or blemishes in the stone.
