CONVERGENT Pentra-Sil® (244+) - Lithium Densifier and Concrete Sealer
Pentra-Sil® (244+) is a high-performance lithium hardener, densifier and sealer. It is formulated to protect existing concrete against damage from salt, freeze-thaw, moisture and steel corrosion. Pentra-Sil® (244+) reduces chloride ion intrusion, dustproofs, hardens and fortifies the surface. It is easy to use and VOC compliant.
