Adhesives Technology Pentra-Sil (IH) Polishing Densifier, 5 Gallon Pail
Pentra-Sil (IH) from Adhesives Technology is a Nano-Lithium impregnating hardener made for concrete polishing. Applied during honing, it hardens terrazzo, stone, and polished concrete so abrasive tooling cuts more effectively and the finish gains gloss and clarity. One coat, no brooming or rinsing, and it will not skin, discolor, or leave white blemishes on the surface.

Frequently Asked Questions
Is Pentra-Sil (IH) meant to be used during polishing?
Yes. Pentra-Sil (IH) is an impregnating hardener specifically for concrete polishing. Applied during the polish, it hardens the surface so abrasive tooling works more effectively and the final appearance is clearer.
Does Pentra-Sil (IH) need brooming or rinsing?
Pentra-Sil (IH) is a simple one-coat lithium with no brooming or rinsing during application. It will not skin, film, discolor, or leave white blemishes when used as directed on the current IH sheet.
Will Pentra-Sil (IH) leave a film on terrazzo or stone?
No. Pentra-Sil (IH) is an impregnating Nano-Lithium densifier. It preserves the natural look of concrete, terrazzo, and stone while it raises gloss, clarity, and abrasion resistance and cuts dusting.
Does Pentra-Sil (IH) help diamond tooling last through a polish?
Yes. A harder surface lets abrasive tooling cut more effectively. That is the polish-floor reason to keep Pentra-Sil (IH) in the sequence rather than a hydrophobic salt-protection densifier.
Is Pentra-Sil (IH) GreenGuard Gold listed?
Pentra-Sil (IH) carries UL 2818 GreenGuard Gold certification for low chemical emissions. That listing is why occupied interiors keep IH on a polish spec that still needs a lithium hardener.
Does Pentra-Sil (IH) reduce dusting on a polished slab?
Yes. Pentra-Sil (IH) improves abrasion resistance and reduces dusting while it raises gloss and clarity. Dust cut is a polish-floor result, not a chloride-sealer claim.
