Pentra-Sil® (AC)


Pentra-Sil® (AC) is an advanced alkalinity control treatment that reacts with concrete to neutralize its pH levels. Through this permanent reaction, slab sweating and efflorescence is significantly reduced. The lithium silicate in this product also densifies and hardens the surface, increasing abrasion resistance.
