Pentra-Sil® (H)


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 one application, will not peel, and no rinsing is required. This solution is VOC compliant and easy to apply.
