If you live in an area where deicing salts were used on the roadways the best choice to seal your concrete from all sorts of damage is Siloxa-Tek 8500. This silane/siloxane based sealer is formulated with two component solutions that contain an optimized ratio of silane and siloxane particles. Silane is a mild penetrating particle that will penetrate past the surface of the concrete to lock out water. The siloxane particles will then spread out over the surface to lock out threats. These two types of particles work in concerte to create a solid hydrophobic barrier to help increase your concrete driveways resistance to the elements. Not only is Siloxa-Tex 8500 the highest quality driveway sealer but it is also Department of Transportation approved. The Siloxa-Tek 8500 will protect the driveway from deicing salts, freeze-thaw cycles, spalling, pitting and cracking.
If you are looking for additional protection from oils and staining from leaves the best products to use are the Siloxa-Tek 8505 water-based or the Siloxa-Tek 8510 solvent-based. These two products will give you all the protection and benefits of the Siloxa-Tek 8500 with added stain resistance.
