Prosoco Consolideck LS


SKU: 0000002055 Categories: , ,


Prosoco’s Consolideck LS is the premium hardener, densifier and sealer for concrete surfaces. This penetrating lithium silicate treatment reacts with the concrete to produce insoluble calcium silicate hydrate within the concrete pores. Treated surfaces resist damage from water and surface abrasion. The increased surface hardness imparted by LS reduces dusting and simplifies maintenance producing a cleaner, healthier environment.

LS is safer, faster and easier to apply than conventional sodium or potassium silicate hardeners, LS will not trigger or contribute to surface ASR (Alkali Silicate Reaction).
