Diamond-MTP is used in conjunction with epoxy and epoxy novolac lining systems for priming concrete. This state-of-the-art curing system provides excellent adhesion to concrete at temperatures as low as 65° F. It is highly resistant to amine blush even when cured at low temperatures and high humidity. Diamond-MTP exhibits superior adhesion to concrete and higher tensile and flexural strengths when compared to conventional epoxy primers. Diamond-MTP can also be used when calcium chloride tests exceed limits of standard epoxies. See DiamondStone® Moisture Limits and Testing Policy for moisture parameters. Project description and calcium chloride test results need to be sent to DiamondStone Technical Department for approval prior to installation.

DIAMOND-MTP is a high-performance, low-viscosity modified polymer used for concrete surfaces. Diamond-MTP reduces vapor emissions to a level acceptable for a wide range of non-breathable floor goods, while providing outstanding penetration to concrete.



Apply only to clean and sound concrete substrates that are free of all coatings, sealers, curing compounds, oils, greases or any other contaminants. 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. NOTE: Although testing is critical, it is not a guarantee that future challenges will not arise. The DiamondStone Technical Department needs to be consulted prior to any Green concrete applications. 





DiamondStone, LLC warrants its products to be free from defects in material and workmanship. DiamondStone, LLC’s sole obligation and Buyer’s exclusive remedy in connection with the products shall be limited, at DiamondStone, LLC’s option, to either replacement of products not conforming to this warranty or credit to Buyer’s account in the invoiced amount of the nonconforming products. Any claim under this warranty must be made by Buyer to DiamondStone, LLC in writing within five (5) days of Buyer’s discovery of the claimed defect, but in no event later than the expiration of the applicable shelf life, or one (1) year from the delivery date, whichever is earlier. Buyer’s failure to notify DiamondStone, LLC of such nonconformance as required herein shall bar Buyer from recovery under this warranty.

This Limited Warranty is exclusive and in lieu of all other warranties of any kind or nature whatsoever. DiamondStone, LLC makes no other warranties concerning this product. No other warranties, whether expressed, implied or statutory, shall apply. All other warranties, including, but not limited to, implied warranties of good performance, merchantability and fitness for particular purpose are hereby excluded and disclaimed. In no event shall DiamondStone, LLC be liable for consequential or incidental damages.

Any recommendation or suggestion relating to the use of the products made by DiamondStone, LLC, whether in its technical literature, in response to specific inquiry, or otherwise, is based on data believed to be reliable; however, the products and information are intended for use by Buyers having requisite skill and know-how in the industry, and therefore it is for the Buyer to satisfy itself of the suitability of the products for its own particular use, and it shall be deemed that Buyer has done so, at its sole discretion and risk. Variation in environment, changes in procedures of use, or extrapolation of data may cause unsatisfactory results. DiamondStone, LLC cannot guarantee that color will conform to sample, if provided.



Do not apply when concrete temperatures are less than
65° 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 65° 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. Actual color may vary slightly upon application.
