DiamondCast Novolac System®




DIAMONDCAST NOVOLAC SYSTEM is a multifunctional polymer coating formulated to provide maximum chemical resistance to 98% sulfuric acid and other aggressive chemicals. DiamondCast Novolac System provides excellent durability due in part to the microfibers incorporated into the resin that act as stress relievers, enabling the floor to relax after an incident. This resilience provides excellent scratch resistance. 


IMPACT RESISTANCE: DiamondCast Novolac System uses a proprietary grinding process during installation. This process densifies the floor, raising compressive strength and providing outstanding impact resistance. 

CHEMICAL RESISTANCE: DiamondCast Novolac System has excellent chemical resistance to aggressive acids, including 98% sulfuric. Refer to DiamondStone Chemical Resistance Guide for specific chemical and concentration resistance. 

ABRASION RESISTANCE: DiamondCast Novolac System provides excellent abrasion resistance in a novolac coating. 

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

DiamondCast Novolac System is formulated specifically to resist direct contact with most inorganic acids such as 98% sulfuric acid, phosphoric acid and hydrochloric acid. Because of its compatibility with concrete, it is ideal for process-area floors, secondary containment and truck loading/unloading areas. DiamondCast Novolac System is also recommended for pump pads, pedestals, curbs, dike walls and battery charging areas. DiamondCast Novolac System provides excellent thermal compatibility with concrete when compared with conventional coatings.


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. 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.
