Hardener, Densifier and Sealer
Pentra-Sil® (HD) is a premium lithium polysilicate performance densifier for concrete surfaces. This high solids formula provides maximum hardening to improve abrasion resistance and reduce dusting. This easy-to-use water-based solution requires no rinsing and is VOC compliant in all areas of the world. When sprayed on new or existing concrete, it penetrates up to ¼ inch (7mm) where it reacts with free calcium to form insoluble calcium silica hydrate, which makes concrete more water, stain, and abrasion resistant for easier maintenance and longer life. It is also suitable for concrete polishing procedures and helps prolong the life of polished finishes.
