In order to keep marble floors looking their best, regular maintenance is required. Buffing the floors helps them retain the ability to reflect light, creating a constantly changing pattern in varying intensity thats a large part of the charm of a marble floor. However, buffing is not enough to retain the beauty of your floors. Marble is vulnerable to etching from acidic materials, which can appear as a stain on the marbles surface. Applying a sealant to your floor creates a protective layer that can slow the etching process long enough to clean the marble. The combination of buffing and sealing is a significant part of the maintenance process that keeps your floor looking as beautiful as on the day of installation, even after decades of use.
