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 alkali salts and sweating. (For serious problems we recommend a full treatment of Pentra-Sil® (C&N), Pentra-Sil® AC), and Pentra-Sil®(HD). Pentra-Sil®(C&N is also excellent for cleaning concrete after diamond polishing.Pentra-Sil®(C&N) removes fine particles and dust that can reduce shine.
