Polished Concrete Densifier

C2 Hard provides an advanced alternative to conventional sodium or potassium silicate surface hardeners. This penetrating silicate treatment reacts with the concrete to produce insoluble calcium silicate hydrate within the concrete pores. C2 Hard is appropriate for freshly troweled “green” concrete, or existing floors of any age and renders concrete floors dustproof. Unlike conventional hardeners, which deposit high concentrations of sodium or potassium salts, C2 Hard will not trigger or contribute to surface ASR (Alkali Silicate Reaction).
