ClearSteel – CS100

A Remarkable Solvent Borne Silane Complex That Keeps Substrates Free of Discoloring Algae & Mold, is Water Resistant & Fire Resistant

CS100 is a remarkable, breakthrough silicone sealant: (1) it stops discoloring from ugly algae, mold and fungi (“microorganisms”) on brick, masonry, stucco, grout, concrete, stone, vinyl, tile, plaster, roofs, wood and drywall for years, (2) it retards fire from spreading on combustible surfaces and (3) it prevents water entry – it is salt water proof. ClearSteel molecularly bonds to a substrate forming a seamless, durable barrier. Once cured the surface is harmless to humans and pets. ClearSteel protects and keeps treated surfaces clean, attractive to look at, maintaining value and keeping surfaces environmentally healthy.
