Deep SubSurface / water repellant concrete Hardener/

Highly Abrasion Resistant

HydroShield gives a natural look to concrete

Green Umbrella™ HydroShield

Green Umbrella™ HydroShield is a densifier designed to repel water.  A powerful hydrophobic – HydroShield is an environmentally friendly concrete hardening densifier that deeply penetrates and chemically reacts with concrete to create a floor surface that is harder and denser.  A clear, odorless solution, HydroShield does not require rinsing and removal, saving considerable time and money while eliminating hazardous waste disposal issues — significantly reducing your company’s impact on the environment.


Varied Locations: Green Umbrella™ HydroShield is specially formulated for use in manufacturing & light assembly plants, warehouse/distribution centers, food service operations, retail stores & showrooms, parking decks, garages, airports, hospitals and wherever concrete surfaces are maintained. It can be used for indoor or outdoor concrete.

HydroShield’s Primary Feature

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