Seal Hard

SEAL HARD is a proprietary, colorless, environmentally safe chemical solution that increases the wear surface strength of concrete floors subjected to pedestrian and vehicle traffic.

SEAL HARD penetrates concrete surfaces to seal, dustproof, densify and harden them. SEAL HARD floors last longer, cost less to maintain, are safe to use, and are guaranteed to resist dusting for years after application.

Through a chemical-ion exchange process, SEAL HARD develops internal bonds which densify the concrete substrate into a hardened, chemically-cured, homogeneous concrete mass that dustproofs, resists abrasion, and reduces oil and water penetration.. This chemical-ion densifying process begins immediately upon treatment and continues through the initial six months following application, at which time the treatment becomes complete and permanent.

With its odorless, VOC free formula, SEAL HARD is environmentally safe to use. SEAL HARD is also safe to own. The deeply penetrating chemical action leaves no film and will not alter the natural non-slip texture of the concrete floor. Treated floors conform to ADA and OSHA requirements.

SEAL HARD treated floors provide a significant savings in maintenance costs over conventional acrylic, epoxy and urethane sealers. SEAL HARD will not yellow, discolor, chip, peel or show unsightly wear patterns with use. SEAL HARD treated floors resist tire marks. In fact, the more a SEAL HARD floor is used and as it matures, the better it looks and more durable it becomes.

Basic Use:

SEAL HARD is recommended for use in high performance areas subjected to fork lift and tow motor traffic: warehouses, distribution centers, manufacturing plants, textile mills, bottling plants, coolers and freezers, food processing plants, canning factories, breweries, bakeries, meat and poultry processing plants, service garages, grocery stores, discount retail stores, hub transfer facilities.

Other uses include concrete floors subjected to heavy pedestrian traffic, such as: civic centers, sports arenas, stadiums, hospitals, airports, museums, schools and grocery stores; parking decks, sewage treatment plants, dairies, fish processing plants, refineries and water treatment plants.
