Pentra-Sil® (HD)



Pentra-Sil® (HD) is a high solids Nano-LithiumⓇ densifier that provides optimal hardening and adds a slight sheen to the surface of the substrate. Pentra-Sil® (HD) is best for existing concrete surfaces to increase abrasion and stain resistance and eliminate dusting. It is also suitable for concrete polishing procedures, enhancing the surface appearance and prolonging the life of polished finishes. This solution is VOC compliant in all areas of the world.


• Increases abrasion resistance

• Penetrates, no film to lift or peel off

• Reduces efflorescence and surface sweating

• Does not contribute to surface ASR or promote crazing

• Prolongs finish of polished surfaces

• Resists stains and dusting, making concrete and facilities easier to maintain

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


Machine-troweled: 550-750 ft² per gallon (13.5-18.4 m² per liter)

Broom-finished: 200-400 ft² per gallon (4.9-9.8 m² per liter)

*Coverage rate will vary with concrete porosity and environmental conditions.
