Pentra-Sil (H) 5 Gallon Pail

Pentra-Sil (H) is the preferred Nano-Lithium® densifier for freshly placed concrete and tilt-up construction slabs. It can also be used on existing concrete surfaces and cementitious overlays. This fast-drying, reactive formula provides maximum hardening to improve abrasion resistance and reduce dusting with a simple, one-coat application. If desired, curing compounds can be applied directly on top of the treated surface once it is dry.

Pentra-Sil (H) creates an extremely hard surface that is dense yet breathable. When applied to new concrete, it penetrates up to ¼ inch (7mm) where it reacts to form insoluble calcium-silica-hydrate, making concrete more water, stain, and abrasion resistant for easier maintenance and a longer life. The treatment leaves no film, reduces application time and cost, and allows most curing compounds to be more easily removed. This easy-to-use, water-based solution requires no rinsing and is VOC compliant.
