Concrete Solutions® Moisture Guard is a water based colloidal silicate densifier, which is non-hazardous, zero VOC’s, and creates a permanent integral barrier that both densifies concrete through increased hydration and protects concrete from chemical attacks from a greatly reduced permeability.

Moisture Guard is a proprietary formulation in an aqueous base, which is safe and easy to apply.

Features & Benefits:
  • Exhibits deep a high degree of penetration without leaving any residue on the surface
  • Significantly decreases un-hydrated cement (free alkali) thereby increasing concrete’s density
  • Greatly reduces permeability
  • Highly effective in protecting the concrete surface against acid & salt/chemical erosion
  • Formulated using “green technology” and LEED credit qualification
  • No harmful fumes or objectionable odors for trouble-free applications on interior projects
  • Ready to use formula allows for easy application and labor cost savings on the job
Coverage Rates:
  • Broom Finish: 150-200 ft² per gal
  • Trowel Finish: 200-300 ft² per gal
Typical Uses:

​Moisture Guard is recommended as a densifier and moisture vapor blocker prior to the application of:

    • cementitious overlays
    • epoxy coatings
    • traditional flooring materials
    • concrete polishing applications
