HG tile impregnator HG tile impregnating protector (HG product 13) is a special, basic treatment for (new) unglazed tiles or flagstones. This unique product prevents the absorption effect and thus prevents the penetration of dirt and grease stains without affecting the original character of the tile or sealing the floor off. This product is suitable for all types of porous and lightly porous tiles and flagstones, and can be used both indoors and out. Apply the liquid evenly in one direction, using a paint roller. Now leave to work for 10 minutes and then remove any leftover product using a dry, lint free cloth. Depending on the type of material, 1 litre of this product is sufficient for up to 40 m2 floor area.
