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.
UL 2818 – 2022 GreenGuard Gold Certification for low chemical emissions - Gold Standard for Chemical Emissions for Building Materials, Finishes and Furnishings

SlabArmor™ Closer is the second step in the SlabArmor system. This colloidal silica densifier/hardener is applied after power troweling has been completed. A single application is applied to the surface and requires no scrubbing or rinsing. Its reactive...
Pentra-Cure™ (MH) is an eco-friendly, all-in-one treatment that cures, hardens and densifies fresh concrete with one application. It provides long-term protection for commercial and industrial floors against heavy wear and abuse. This unique solution forms a membrane on...
Pentra-Sil® (HDS) is engineered for polished, colored, dyed or acid-stained cementitious surfaces and is ideal for polishing and restoring worn and damaged flooring. This eco-friendly lithium solution hardens, densifies, and seals concrete, overlays, and terrazzo. It enhances color,...
Pentra-Shield® is an exterior concrete and masonry surface hardener and densifier that provides freeze-thaw, scaling and spalling protection. This treatment strengthens concrete sidewalks and driveways to minimize damage caused by winter weather. Pentra-Shield® is a penetrating, breathable solution...
Pentra-Sil® (H) provides maximum hardening for concrete slabs and tilt-up construction. This lithium-based, pre-cure hardener reduces dusting and makes the surface more water, stain and abrasion resistant while increasing surface sheen over time. Pentra-Sil® (H) is applied in...
Not only is it remarkably easy to apply, but it can be applied at temperatures as low as 25°F – and no rinsing is required, making it not only simple but also easy on the environment. It can...
