Lithi-Tek 9500 is an industrial grade, penetrating concrete sealer, densifier and waterproofer. Through densification, concrete's pores, voids and tracts are filled and concrete's compressive strength is increased. In conjunction, an invisible hydrophobic barrier is created on the surface to prevent the penetration of water, fluids and any other contaminants the surface may come into contact with. This unique blend is industry leading and is extremely multifunctional with a variety of applications.
If you live in an area of the country that is exposed to deicing salts the best option would be the Siloxa-Tek 8500. The Siloxa-Tek 8500 is able to resist deicing salt damage and freeze-thaw cycles. It can also be used on brick, stone, and pavers whereas the Lithi-Tek 9500 can only be used on poured concrete sidewalks. If you are looking for additional protection from staining of oils, grease and leaves the best option will be the Siloxa-Tek 8505.
