Most natural stone is porous, some more than others. Porosity ranges from very high (sandstone) to very low (granite) or negligible (porcelain). The natural structure of stone has very open pores that allow the entry of moisture and stains deep into the stone. Most stains are liquid-based and can contaminate the tile.Limestone is porous and scratches or discolors more easily than other stone surfaces.
