Dayton Superior Pentra-Hard Densifier


SKU: 0000002166 Categories: ,


Pentra-Hard Densifier is advanced lithium chemistry that hardens and dustproofs new and existing concrete. This easy-to-use water-based solution requires no rinsing and is VOC compliant in all areas of the world. When sprayed on new or existing concrete, it penetrates into the concrete, where it reacts with free calcium to form insoluble calcium silica hydrate, which makes concrete more water, stain, and abrasion resistant for easier maintenance and longer life. It is also suitable for concrete polishing procedures and helps prolong the life of polished finishes.


  • Easy application, no rinsing required
  • Penetrates, no film to lift or peel off
  • Reduces efflorescence and surface sweating
  • Does not contribute to surface ASR
  • VOC Compliant, can contribute to LEED points
  • Prolongs finish of polished surfaces
  • Resists stains and dusting, making concrete easier to maintain.

Uses for New and Existing Concrete:

  • Commercial: Grocery Stores, Office Building, Retail, Banks, Malls, Warehouses, Distribution Centers
  • Industrial: Food Processing Facilities, Cold Storage / Freezers, Beverage and Manufacturing Plants
  • Institutional: Churches, Hospitals, Universities, Schools, Museums
  • Theme & Leisure: Resorts, Hotels, Casinos, Restaurants, Theaters
  • Governmental: Federal & State Buildings, Prisons
  • Residential: Concrete floors and Garages

For applications where greater shine and stain resistance is required (schools, restaurants, retail, grocery, commercial, etc.) the Durable Floor System (DFS) is recommended. For this system, Pentra-Hard Finish is applied directly over the top of Pentra-Hard Densifier.
