Additional Details

Stifel SC is Nox-Crete's top-performing silane sealer for horizontal concrete surfaces, such as bridges, parking decks, garages and other trafficable areas. Surfaces treated with Stifel SC are in effect guarded against damage from freeze/thaw cycles, deicing salts and the absorption of water – without modifying the surface appearance.

Stifel SC is a water-based and contains a premium silane, which has a molecular structure small enough to penetrate concrete up to ½ inch or more. Stifel SC then reacts with siliceous material to form a hydrophobic barrier that prevents water and waterborne chloride absorption. The SC formulation contains 15% active solids, and is therefore the highest quality Stifel sealer.

Stifel SC is safe and easy to use. Its single-component formulation is very low odor and has a high flash point (>200° F/100° C).


• Exterior horizontal trafficable or structural concrete surfaces such as bridges, parking decks, garages, ramps, traffic ways, cast-in-place concrete and precast concrete

• New or existing substrates

• Where conventional silanes containing hydrocarbon solvent carriers are not safe for use
