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
Engineered for parking and maintenance facilities

Colloidal Silica Concrete Curing/Finishing Aid and Hardener
SlabArmor™ Starter is a colloidal silica concrete curing/finishing aid and hardener used in the placement and finishing of new concrete. Its hydrophilic property holds bleed water in the capillaries of the concrete slab during the curing process, reducing...
High-Performance, High-Gloss Concrete Finisher and Sealer
Seal&Shine Finish is the final step in the SlabArmor™ system, intended to be applied after the placement and finishing process. This high-performance, high-gloss finish, seals, protects and extends the life of your SlabArmor™ floor, eliminating the need for...
Pentra-Sil® (IH) is specifically designed for application during the concrete polishing process. This penetrating hardener improves the final appearance by allowing abrasive tooling to work more effectively, increasing final gloss and clarity. It reduces downtime between polishing steps,...
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...
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...
