Pentra-Sil® (H)



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.


• Easy application, no rinsing required

• Penetrates, no film to lift or peel off

• Bond-breakers can be applied directly on top for tilt-up construction applications

• Reduces efflorescence and surface sweating

• Does not contribute to surface ASR, or surface crazing

• Compatible with integrally colored concrete, stains and dyes

• Curing compounds are more easily removed with scrubbing

• Resists stains and dusting, making concrete easier to maintain

• VOC compliant, may contribute to LEED points (IEQ credit)
