Prosoco LS/CS Concrete Densifier

Prosoco LS/CS Reactive Silicate Hardener/Densifier and Dustproofer for Concrete

Prosoco LS/CS Hardener/Densifier is a blended, reactive silicate hardener/densifier, and dust-proofer for concrete.  Prosoco LS/CS penetrating silicate treatment reacts with concrete to produce insoluble calcium silicate hydrate within the concrete pores. Unlike conventional hardeners which deposit high concentrations of sodium or potassium salts, Prosoco Consolideck LS/CS contains lithium, and it will not trigger or contribute to surface ASR (Alkali Silicate Reaction). It is available in 1 gallon, 5 gallon, and 55 gallon containers. 

How to Use:

Prosoco LS/CS is a penetrating silicate treatment that hardens, densifies and dustproofs 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 dust proof freshly troweled “green” concrete, or existing floors of any age.

Use Consolideck LS/CS by Prosoco on freshly troweled "green" concrete or existing floors of any age. This Prosoco product provides an advanced alternative to conventional sodium or potassium silicate surface hardeners.   Prosoco LS/CS is a product of advanced engineering and complies with VOC regulations including the US Environmental Protection Agency and California Air Resources Board.
