Pentra®-Sil (C&N)

Concrete cleaner and neutralizer

Pentra®-Sil (C&N) cleans and neutralizes concrete that suffers from efflorescence, sweating, and other alkalinity problems. Pentra®-Sil (C&N) Lithium fixer for Concrete Efflorescence and Sweating Problems works by infusing lithium ions into the substrate—these ions calm alkali reactions between aggregate and Portland cement thereby reducing the formation of expansive alkali gels and sweating.
