Floor tile sealer for unglazed tiles or flagstones Our impregnated porcelaine tile sealer does not contain silicon, it dries quickly and is suitable for all types of porous to slightly-porous tiles and flagstones and can be used both indoors and outdoors. Depending on the type of material, 1 litre is sufficient for up to 40m² of floor surface. How do you use HG tile impregnating protector? Follow the steps below for correct use of HG tile impregnating protector (HG product 13). Apply the ceramic tile sealer undiluted, evenly, and in one direction preferably with a paint roller. If 10 minutes after applying some product is still left on the tiles and has not been absorbed, it must be removed immediately with a dry and lint-free cloth. The floor can be walked on about 3 hours after treating and is completely protected about 12 hours after the last treatment.
