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