Quit replacing your concrete floor coating over and over.

SEAL HARD, our "top of the line," new generation concrete chemical hardener, densifier, dustproofer, and sealer, comes with a 10-year warranty*.

SEAL HARD, from L&M Construction Chemicals, hardens and seals the concrete near surface wear zone better than any product in its class. It prevents tire marking and minimizes contaminant penetration.

With its odorless formula, SEAL HARD is safe to use… and safe to own. It is VOC-compliant, odorless, environmentally safe and simple to apply. The deeply penetrating chemical action leaves no film and will not alter the natural non-slip texture of your concrete floor.

SEAL HARD is recommended for use on ACI Class 4, 5, and 9 (super flat) floors, and for Class 6 industrial floors. USDA approved.

* Ten-year warranty against dusting if applied by an Approved Applicator
