Product information

C² Concrete Hardener Products include C² Super Hard™, C² Hard™, C² Hard Blend™, C² Seal™ and C² Salt Hard+™.

C² Concrete Hardener Products are lithium silicate hardeners and densifiers for concrete surfaces. They are a more effective alternative to conventional sodium or potassium silicate hardeners. The patented lithium silicate treatment deeply penetrates and reacts with the concrete to produce insoluble calcium silicate hydrate within the concrete pores. Conventional hardeners deposit high concentrations of sodium or potassium salts, which contribute to surface ASR, resulting in deterioration of concrete. Surfaces treated with C² Concrete Hardener Products will resist damage from water, surface abrasion, eliminate dusting and simplify maintenance.
