DryShield™ Concrete Hardener & Densifier


Green Umbrella® DryShield™ is an environmentally-friendly concrete hardener and densifier. Reaching deep within the subsurface, DryShield creates more than a conventional shell surface.The unique formulation is insoluble, fully reactive, and pH neutral-resulting in a bond within the concrete that is harder, denser, and less porous while allowing maximum penetration of concrete colorants. A breathable, transparent, odorless solution specially formulated as a CrossOver™ densifier. Designed for application @EarlyAge™, @Profile&Polish™, or @MatureAge™. Unlike conventional hardeners, DryShield is a single application S.O.L.O™ treatment that requires no scrubbing or mopping. It does not require a pH balance of wastewater if rinsed. DryShield produces a substrate that will stain less and wear longer, reducing maintenance frequency and extending the concrete’s lifecycle.

As water evaporates from the riverbed’s surface, the mud slowly shrinks and pulls apart, leaving what looks like valleys and canyons up close. When the rain returns, the water hydrates the cracked and dry dirt, filling the voids. Magnified concrete looks similar. DryShield flows into the concrete’s valleys, canyons, and craters and fills them, becoming part of the concrete and creating a tight surface. DryShield is a penetrating, completely reactive, hydrophilic insoluble nano densifier.

  • No VOCs and environmentally responsible
  • Non-resinous polymer formulation that prevents yellowing and tire marking
  • 2-3x greater coverage rate of conventional floor products, cutting labor
  • (Low viscosity, high detergent, and chlorinated oils require MaxDefense™)
Additional Features & Benefits for @EarlyAge™ Concrete
  • Does not require calcium hydroxide reaction and may apply the same day as pour
  • No 7- to 28-day application restriction, meaning less downtime
  • Not a desiccant and will not damage cure of surface
Additional Features & Benefits For Abrasively Polished Concrete
  • Designed for wet profile, hone, and polish process No slab whitening
  • Combines with nano colorant and is a one-step color densifier
  • Special formulation provides increased concrete colorant retention
  • No concrete sweating after application, preventing long downtime for slab recovery
  • Deeply subsurface and won’t cut off during profiling, honing, and polishing stages
Standards and Testing
  • ASTM C779
  • ASTM C1583
  • ASTM 1308 with the MaxDefense™ system
  • USDA compliant
  • FDA approved

The product application is formulated for open concrete with 400 to 500 square feet per gallon. With a cutting agent, like GreenCut®, the product requirement usage increases to 600 square feet per gallon. Conventional concrete hardeners are typically applied at 150 to 300 square feet per gallon. DryShield is a S.O.L.O.™ treatment that only requires one application, unlike common hardeners.
