DiamondCast Natural System®




DIAMONDCAST NATURAL SYSTEM is a double-broadcast epoxy flooring system engineered with stress-relieving flexibility. DiamondCast Natural System contains washed and sized aggregate without coloration, providing a natural concrete look that is durable, cleanable and slip-resistant. 


DECORATIVE: DiamondCast System has an aggregate-filled receiving coat with a full saturation broadcast layer of special aggregate to provide a complete color-hide.


IMPACT RESISTANCE: DiamondCast System has stress-relieving flexibility incorporated into the system, providing excellent impact resistance. 

UV RESISTANCE: The DiamondCast System has good UV resistance. For upgraded UV resistance, install Polyaspartic Urethane® as a grout and seal coat. 

CHEMICAL RESISTANCE: DiamondCast System has good chemical resistance to most minor solvents and acids. Refer to DiamondStone Chemical Resistance Guide for specific chemical and concentration resistance. 

ABRASION RESISTANCE: DiamondCast System has good abrasion resistance. The addition of the optional Polyaspartic Urethane increases this resistance. 

LEED® QUALIFIED PRODUCT: DiamondCast System meets the requirements to be considered a LEED-accredited product as defined by the U.S. Green Building Council.

DiamondCast Natural System is ideal for use where a decorative natural look is desired. DiamondCast Natural System has outstanding impact and abrasion resistance and is resistant to most mild solvents and acids. This makes DiamondCast Natural System ideal for installations in manufacturing, auto service and commercial environments.  




Apply 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. Moisture testing of the concrete surface should be performed pursuant to ASTM E-1907 moisture testing specification. See DiamondStone Concrete Moisture Limits & Testing Policy for project-specific testing requirements and, if necessary, moisture tolerant options. Bare concrete should be tested for pH and exhibit a pH between 7 and 11. NOTE: Although testing is critical, it is not a guarantee that future challenges will not arise. 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.



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.



Do not apply when concrete temperatures are less than 50° F or greater than 95° 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 45º F and 85° F. Confirm product performance in specific chemical environment prior to use. Substrate temperature must be at least 5° F above the dew point. Please take this into consideration. Actual color may vary slightly upon application. 


Is available with the addition of OX-Grit 30 or OX-Grit 60
