Equalizes Surface pH
Mitigates Efflorescence and Sweating Slab Syndrome
Increases Suface Durability


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.

  • Reduces sweating and efflorescence
  • Neutralizes the surface and reduces alkalinity
  • Reduces vapor drive that carries alkaline salts to the surface of concrete
  • Densifies and hardens the surface to increase abrasion resistance
  • VOC compliant, may contribute to LEED points (IEQ credit)
