Consolideck LS/CS Hardener/Densifier & Dustproofer

Consolideck LS/CS Hardener/Densifier & Dustproofer

Reactive silicate hardener/densifier and dust proofer for concrete
LS/CS is a penetrating silicate treatment that hardens, densifies and dustproof concrete flatwork. Unlike conventional hardeners, it does not have to be scrubbed or flushed. Simply spray LS/CS on the surface and spread it out with a microfiber pad. LS/CS will not trigger or contribute to surface ASR (alkali silicate reaction) and will dustproof freshly troweled “green” concrete, or existing floors of any age.

Consolideck® LS/CS 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. LS/CS 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, Consolideck LS/CS will not trigger or contribute to surface ASR (Alkali Silicate Reaction).
