Things You Will Need
Seal your limestone immediately after installation and then again about once a year.
-
Mop the limestone with a neutral cleaner -- if your limestone is particularly dirty, use an alkaline stone cleaner. Let the cleaner sit on the limestone flooring for at least 10 minutes and then scrub the floor with a deck brush. Rinse the floor with clean water and let it dry completely.
-
Apply an impregnating sealer to the stones using a soft cloth, such as lambswool. Do not let the sealer puddle. Allow the sealer to dry per the manufacturer's instructions.
-
Apply a second coat of sealer with a soft cloth.
-
Buff the limestone after the second coat dries using a microfiber or cotton cloth.
