Highly Abrasion Resistant




DryShield Gives a Natural Look to Concrete


Green Umbrella™ DryShield

How do you create an architectural concrete floor that combines beauty and durability?  Green Umbrella™ DryShield is an environmentally friendly concrete densifier that deeply penetrates and chemically reacts with concrete to create a floor surface that is harder, denser and less porous, while allowing for maximum penetration of concrete colorants.  A clear, odorless solution, Green Umbrella™ DryShield is specially designed to fill the voids in concrete.

DryShield 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.  Designed to work seamlessly within a wet profile, hone, polish process of concrete grinding. 

Nearly 15 years of thoughtful research and field work have gone into the making of Green Umbrella’s environmental team approach to Architectural flooring design. With so many components, we have made what seems complex, simple, by creating “Architectural Concrete Floor Systems”.  See how DryShield works within our System approach.


Varied Locations: Green Umbrella™ DryShield 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

DryShield’s Primary Feature: Insolubility

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

CUT YOUR LABOR. With DryShield™ there is no auto-scrubbing required.

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

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