What are topical sealers/ coating, and how do they work?
‘Topical’ sealers or coating sealers provide protection by forming a barrier coating on the surface of the tile or stone. They bond into the top layer sometimes by partly penetrating into the pores of the tile, and are then usually visible on the surface. Some specific types of coating sealers have allowed small amounts of moisture migration into and out of the stone, but most often these sealers are impervious, preventing the entry of almost all types of contaminants.
Topical sealers can also be used to provide wear protection for some of the softer stones such as limestone and marble, providing an easier-to-maintain finish than the stone itself.
