ConBlock HP: Lithium-Based Surface Hardener
ConBlock HP is a high-performance penetrating concrete sealer made from a propriety blend of inorganic materials that react with Portland Cement Concrete to create crystalline formation within the concrete pore structure. ConBlock HP is used to improve the durability, chemical resistance and hardness, as well as reduce the porosity of poured concrete. There is no scrubbing, washing or flushing needed when applying ConBlock HP to concrete flooring applications. Concrete HP will produce a hardened concrete surface with a satin gloss. The gloss may improve over time with washing and buffing operations. The concrete will remain breathable while resisting the penetration of liquids or moisture. Concrete floors will not sweat, making ConBlock HP suitable for applications where a laminated floor will be applied.
