Euco Diamond Hard is a unique blend of silicate and siliconate polymers that penetrate concrete surfaces and chemically react to provide an increase in surface density, durability, and abrasion resistance. Concrete treated with EUCO DIAMOND HARD is dust-proofed, resists tire marks, and is easier to maintain. Over time, EUCO DIAMOND HARD provides an attractive, slip resistant sheen to concrete that never peels, fades, or wears away. Questions? Contact Us

EUCO DIAMOND HARD should be used directly from the container and requires no pre-mixing or blending.
Surface Preparation (Newly Placed Concrete): Cure the concrete by a wet or sheet cure method in accordance
with ASTM C-171, or with a curing compound such as KUREZ DR VOX. New concrete should cure seven days or
longer before application of DIAMOND HARD. For fast track projects, the wet cure time may be reduced at the discretion of the project engineer. Remove the curing method, including any laitance formed on the surface, and allow concrete to air dry a minimum of 24 hours prior to application of  DIAMOND HARD. If a curing compound is used, it must be fully removed before applying DIAMOND HARD. Failure to follow these preparation steps will prevent full penetration of EUCO, drastically reducing its effectiveness.
Surface Preparation (Existing/Older Concrete): Concrete that is already in service or older floors must be clean and
free of any materials that could prevent penetration of EUCO DIAMOND HARD, such as curing compounds or cure & seals, paints, coatings, dirt/oil, waxes, etc. If necessary, use EUCO CLEAN & STRIP to remove these contaminants
before applying EUCO DIAMOND HARD.

Application (New or Old Concrete): Air temperature during application must be between 35°F and 100°F (2°C and
38°C). At temperatures below 50°F (10°C), the reaction and “gelling” process of EUCO DIAMOND HARD is slower,
so the concrete will need to remain wet with EUCO DIAMOND HARD for a longer period of time. In hot or windy
conditions, the reaction may take less than the normal 30 to 60 minute period. Concrete should be pre-dampened
in hot weather; apply EUCO DIAMOND HARD when all standing water has disappeared. Apply the EUCO DIAMOND HARD to the concrete surface by low pressure sprayer or by pouring directly onto the surface and distributing evenly by broom or squeegee. With soft bristle hand brooms or brushes on an auto-scrubber, work the EUCO around the area to be treated and into the surface. The concrete must be kept wet with EUCO for at least 30 minutes – add additional EUCO DIAMOND HARD if necessary to maintain a wet surface. As the DIAMOND HARD begins to thicken and gel underfoot, lightly spray the area with clean water to break up the thickened DIAMOND HARD and move the excess material on to the adjacent floor area next to be treated. Do not track EUCO onto untreated concrete, as permanent footprints or tire marks can result. Continue the application process until the entire floor has been treated. When finished, completely remove all excess EUCO from the surface
