Refer to DiamondStone cleaning and maintenance instructions.


Always use protective clothing, gloves and goggles consistent with OSHA regulations during use. Avoid eye and skin contact. Do not ingest or inhale. Refer to Material Safety Data Sheet for detailed safety precautions.



Diamond-Prime is used as a primer coat under any Diamond-Crete product. Diamond-Prime should be used when the potential for excessive outgassing of the concrete slab exists.



Do not apply when concrete temperatures are less than 
40° F or greater than 85° F. (Material cures slower at cooler temperatures, and working time will be substantially reduced at higher temperatures.) All components should be stored in a dry place at temperatures between 45° F and 85° F. Do not thin with solvents. Confirm product performance in specific chemical environment prior to use. Substrate temperature must be at least 5° F above the dew point. Actual color may vary slightly upon application. Product will amber from UV exposure, including UV exposure from facility lighting, unless broadcast with quartz and topcoated with Polyaspartic Urethane.




Apply only to clean and sound concrete substrates that are free of all coatings, sealers, curing compounds, oils, greases or any other contaminants. New concrete should be cured a minimum of 28 days. Concrete that has been contaminated with chemicals or other foreign matter must be neutralized or removed. Remove any laitance or weak surface layers. Concrete should have a minimum surface tensile strength of 300 psi. Prepare surface by mechanical means to achieve a profile equal to industry standards. All surface irregularities, cracks, expansion joints and control joints should be properly addressed prior to application. Outgassing may occur due to the porosity of some concrete surfaces. Refer to DiamondStone® Surface Preparation Guidelines for more details.



CHEMICAL RESISTANT: Diamond-Prime provides excellent protection against attacks from a wide variety of chemicals such as oxidizing agents, mineral acids, organic acids and alkalies. Refer to DiamondStone Chemical Resistance Guide for specific chemical and concentration resistance.
ODOR MINIMIZED: Diamond-Prime is a water-borne urethane cement that is virtually odor free and contains no VOCs.
ANTIMICROBIAL: Diamond-Prime contains a Non-Sacrificial Anti-Microbial additive which inhibits the growth of bacteria and bacterial odors. The inclusion of this additive throughout the entire system ensures the permanency of the biocidal, even in the event of excessive surface wear. 
THERMAL-SHOCK RESISTANT: Diamond-Prime has a similar coefficient of thermal expansion to that of concrete, enabling the product to expand and contract at similar rates. This provides excellent thermal-shock and thermal-cycling resistance.
