Seal Krete SS-10 Clear Silane-Siloxane Waterproofer
The combination of both silane and siloxane means that this sealer offers good water resistance both on the surface and deeper into the actual concrete. The Siloxane is a larger molecule that will essentially plug up some of the pores without changing the visual appearance of the material. Silane is smaller and narrows gets below the surface to narrow rather than plug pores. It has been formulated to resist the UV damage to which silane and siloxane are susceptible, which makes this a long lasting product with good durability.
