Green Umbrella™ HydroShield

 Green UmbrellaTM HydroShield is an environmentally friendly concrete hydrophobic hardener and densifier. Reaching deep within the subsurface, HydroShield creates more than a conventional shell surface. The unique formulation is resist to surface water and is insoluble, 100% reactive, and pH neutral-resulting in a bond within concrete that is harder, denser and less porous, while allowing maximum penetration of concrete colorants. A clear, odorless solution specially formulated to be a “CrossOver” densifier. Designed for application @ early age, @ profile and polish or @ mature age concrete. Unlike conventional hardeners, HydroShield is a S.O.L.O (Spray-On-Leave-On) treatment that requires no scrubbing or mopping during a single application and does not require pH balance of waste water if rinsed. HydroShield produces a substrate that will resist water stain less and wear longer, reducing maintenance frequency and extending the concrete’s life cycle.

Deep SubSurface / water repellant concrete Hardener / Highly Abrasion Resistant

HydroShield’s Primary Feature

Green Umbrella Hydroshield is Insoluble. Once Hydroshield has reacted with the concrete – it will not come out.


CUT YOUR LABOR. With Hydroshield there is no auto-scrubbing.


CUT YOUR DOWNTIME. Hydroshield may be applied the same day as concrete is poured.

CUT YOUR ENVIRONMENTAL IMPACT. Hydroshield uses natural silica to fill the voids.

HydroShield gives a natural look to concrete
