Concrete Densifier and Hardener CDH 4000

Product Description
CDH-4000 Densifier is a blend of inorganic Nano polymer materials that penetrates cementitious surfaces to increase density and hardness. CDH-4000 Densifier’s proprietary formulation of reactive Nano-sized particles penetrates deeply into concrete surfaces bonding with the cement components of the slab. CDH-4000 Densifier’s makes an extremely hard, dense surface that has increased wear resistance to foot and fork lift traffic. It is water based and environmentally friendly and is VOC compliant in all states.

Primary Applications
CDH-400 Densifier can be applied over existing or cured concrete, or while the slab is still green just after final trowel. It can also be used over cementitious *wear toppings.

  • Interior or exterior concrete
  • Residential and Garages
  • Warehouses / Distribution centers
  • Commercial floors
  • Schools / Institutional
  • All concrete surfaces

Application/Directions Protect and cover all surrounding surfaces from over spray. CDH-4000 Densifier can be applied to concrete of any age. Surface must be clean and structurally sound. Surface also must be clear of membrane forming curing compounds, oils, dust and other surface contaminants.

Diamond Grinding /Polishing: Application typically is performed between the 80 and 400 grit stages depending on the surface conditions and the tools used. Use a low-pressure sprayer to apply to form an even sheen across surface to ensure complete saturation of surface. Apply enough material to keep the surface wet for 15 to 20 minutes. Let surface dry 1 hour before continuing.

New Concrete: (Green) CDH-4000 Densifier may be applied to newly installed concrete after final trowel while slab is still Green. Slab must be clean and free of all materials such as curing compounds, bond breakers, release oils, dust and debris, etc. Use a low-pressure sprayer to achieve a consistent, even application and consistent coverage of the surface. Reapply as necessary to keep surface wet for 20 minutes. Let surface dry. No cleaning, flooding, neutralizing, or rinsing is necessary.

Maintenance
Only an approved maintenance product should be used. Consult EST Inc. for more information. Cleaning solutions should be neutral pH. Avoid acidic cleaners and detergents containing hydroxides or high pH sulfates as these may etch or dull the surface.

Storage
CDH-4000 Densifier should be stored in closed sealed in its original container in a cool dry place to maximize shelf life. Shelf life is approximately 1 year.

Clean-up
Clean all tools and equipment with soap and water immediately after use. Residue from application and cleanup is non-toxic. Protect metals, glass, wood, paint or brick from contact with Densifier. Avoid accidental over spray, if occurs, wash and rinse immediately with potable water.
