SpecHard - Intraseal is a proprietary, colorless chemical solution that increases the wear surface strength of concrete floors subjected to pedestrian and vehicle traffic.

SpecHard - Intraseal penetrates concrete surfaces to seal, densify and harden. SpecHard - Intraseal floors last longer, cost less to maintain, are safe to use, and are guaranteed to resist dusting for years after application. It is VOC compliant, odorless, environmentally safe, and simple to apply.

SpecHard - Intraseal penetrates the concrete surface and undergoes a chemical reaction that turns the concrete substrate into a hardened, densified mass.

Surfaces treated with SpecHard - Intraseal are not only more abrasion resistant but are more resistant to chemicals and water than untreated concrete. The deeply penetrating chemical action leaves no film and will not alter the natural non-slip texture of the concrete floor.
