Request Specification


Filling the Voids“Green UmbrellaTM 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, 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 & polish or @mature age concrete. Unlike conventional hardeners, DryShield 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. DryShield produces a substrate that will stain less and wear longer, reducing maintenance frequency and extending the concrete’s life cycle.

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

Deep SubSurface /

PH Neutral Concrete Hardener / Highly Abrasion Resistant

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.

Green Umbrella DryShield

May be applied the day of the pour with no adverse effects

Conventional Concrete Desifier

Wait 28 days after pour for proper concrete reaction


Product application is formulated for open concrete to have 400-500 square feet per gallon. With the use of a cutting agent Green Umbrella GreenCut, the product requirement usage increases to 600 square feet per gallon. Conventional concrete hardeners are applied at 150 square feet per gallon with some formulations being 300. However keep in mind Green Umbrella Dryshield is a  SOLO application (Spray-On-Leave-On) with only one application unlike the common hardeners.
