600 sq. ft. of Pennsylvania Bluestone flooring throughout a kitchen, dinning room, laundry room and mud room in the Pocono Mountains. The stone floor was installed about 4 years ago and the owners are having continuous problems with water and grease spots around the sinks and cooktop areas. We thoroughly cleaned the entire floor and all the grout lines and treated it with a silicone based penetrating sealer. As always the floor looked great after we at Classic Marble & Stone Restoration completed the job
