Pentra®-Sil (H)

At-Time-of-Placement Hardener


Pentra®-Sil (H) is a premium lithium polysilicate hardener for fresh, newly- troweled concrete and tilt-up construction slabs. This fast-drying reactive formula provides maximum hardening to improve abrasion resistance and reduce dusting with a simple, one-coat application. Curing compounds can be applied directly on top of treated surfaces to enhance hydration without the discoloration and whitening associated with traditional hardeners.

Pentra®-Sil (H) provides maximum hardening for concrete slabs and tilt-up construction. This lithium-based product 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.

  • 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)
