Travertine is a limestone and comes either polished or unpolished with a natural matt finish.
It is normally pitted so can trap dirt into the pits in the stone. Larger pits can be filled for easier onward cleaning.
Polished Travertine needs to be burnished with diamond pads using a floor polishing machine. The burnishing process removes old sealers and scratches from the surface and by using different grit pads the stone can be left clean, scratch free and ready for sealing. A full seal with the appropriate sealers can leave your floor looking its best.
