A deep-penetrating sealant that is ideal for treating marble, granite, slate, terracotta, stone, cement and earthenware floors without changing the colour or adding a gloss, leaving the appearance as it was. For greater protection apply a second coat. Allows the treated area to breathe. Apply directly with a short-haired fleece roller or wide paintbrush on a completely clean and dry floor. Water-based. See also Bellatrix Natural Solvent-Based which is a more protective product.
