Pentra-Sil® (IH)



Pentra-Sil® (IH) is an extremely easy to use Nano-Lithium® densifier specifically designed for concrete polishing. Applied during the polishing process, this impregnating hardener improves the final appearance by creating a significantly harder surface that allows abrasive tooling to work more effectively to achieve a superior polish. 

Pentra-Sil® (IH) increases gloss and clarity, improves overall abrasion resistance and reduces dusting. Pentra-Sil (IH) is a simple, one-coat application with no brooming or rinsing required during application. It is easy to apply and will not skin, film, discolor, or leave white blemishes. This lithium-based solution is VOC compliant.
