The Original Lithium Densifier
Stand-alone Densifier/Sealer


*Designed for professional use only

Pentra-Sil® (HD) is a high-performance lithium densifier that provides optimal hardening to improve abrasion resistance and reduce dusting. Pentra-Sil® (HD) is best for existing concrete surfaces to increase abrasion and stain resistance and eliminate dusting. You can also use the treatment during polishing processes. This solution is VOC compliant.

  • 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)
