High Traffic Topcoat®



  • Low-odor formula

  • Excellent chemical resistance

  • Excellent abrasion resistance

  • Excellent UV resistance

  • Excellent color retention

  • 250–300% increased light reflection

  • Built-in slip resistance

  • Qualified LEED® product




High-Traffic Topcoat offers outstanding wear resistance and durability, lasting up to four times longer than standard epoxies. High-Traffic Topcoat incorporates an environmentally friendly formula that, unlike conventional solvent-based polyurethane coatings, gives off little odor during application. This feature is a significant benefit for installations inside areas where occupants are present.  Typical uses are as finish coats over DiamondStone

For industrial and commercial use only. Must be applied by trained personnel only. Do not use lacquer thinners or solvents containing alcohol as thinners. Not for immersion service. Do not apply where ambient operating temperatures exceed 150° F or application temperatures are below 50° F or above 95° F. Do not apply to wet or damp substrates. Do not use on concrete floors with membranes or sealers unless properly removed. Vehicles with rubber tires should not be parked on coating within 36 hours of installation. Floors should be sloped to drain to prevent standing water or chemicals. As with any surface, all spills should be removed as soon as possible to prevent a slipping hazard. Always wear protective clothing, gloves and goggles during use. Do not use in an unventilated area. Please refer to the Material Safety Data Sheet for detailed safety precautions. 



HIGH-TRAFFIC TOPCOAT is a high-performance, 95%-solids, aliphatic, moisture-cured urethane with unsurpassed wear resistance. It offers excellent long-term durability, color retention and UV resistance, along with excellent chemical resistance to most solvents found in manufacturing and industrial areas. High-Traffic Topcoat is an ideal choice for areas with heavy traffic.  



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. 



Do not apply when concrete temperatures are less than 50° F or greater than 85° F. (Material cures slower at cooler temperatures, and working time will be substantially reduced at higher temperatures.) Severe roller marking can occur 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. Material can exhibit roller marks depending upon temperature, humidity and width of area coated. As floor wears in, roller marks dissipate. 

epoxy flooring systems, in a wide variety of indoor or outdoor industrial and commercial applications, including store aisles, corridors, tunnels, airplane hangars, and manufacturing areas.
