Convergent Pentra-Sil IH – 5 Gallon Pail
Pentra-Sil IH is a Nano-Lithium impregnating hardener formulated for polished concrete, terrazzo, and stone. Applied during the polishing process, it hardens the surface so abrasive tooling cuts more efficiently, increasing gloss and clarity, improving abrasion resistance, and reducing dusting. The one-coat treatment is simple to spray, requires no brooming or rinsing during application, remains breathable, and dries clear with low odor and low VOC.
