Series 241 | Ultra-Tread MVT

Generic Type Polyurethane Modified Concrete
Common Usage Ultra-Tread MVT is a high performance moisture control system designed to reduce moisture vapor emissions prior to the application of non-breathing, polymer floor topping finishes. Ultra-Tread MVT is a low odor, self-priming, base coat that can be applied to 10 day old concrete. It can withstand moisture vapor transmission up to 20 lbs (per ASTM F 1869) and relative humidity up to 99% (per ASTM F 2170). This unique, self-leveling slurry system is typically applied by V-notch trowel or squeegee, backrolled with a loop roller and broadcast to refusal with 30/50 mesh aggregate, colored quartz or decorative flake yielding an approximate 1/8" thick base layer.
Colors Neutral/Tan as supplied. Note: Series 244 Part D field colorants are available in 00GR Gray and 00RD Red. Black, blue, beige and green are also available with additional lead time. Series 244 Part D field colorants are ordered separately. When tinting Series 241, add one colorant pack per kit.
Surfacer/Filler/Patcher Series 241 (extended with aggregate) or Series 243. Patching should be allowed to cure a minimum of six hours prior to placement of the Series 241 to avoid blistering or doming of the Series 241. Series 215, or 201 or 208 mixed with fumed silica, may be used for small patches or crack repairs. Certain high-early strength, cementious repair mortars are also acceptable. Contact Tnemec for further qualifications.
Primers Self-priming
Intermediate Series 222, 223, 224, 233, 237, 238, 239, 252SC, 256. Note: Series 241 must be broadcast to refusal with aggregate, colored quartz or decorative flake if topcoating. Broadcast aggregate or colored quartz at an approximate rate of 0.8 lb per sq ft and decorative flake at an approximate rate of 0.25 lb per sq ft or 4 to 5 sq ft per pound. The Series 241 base coat will account for approximately 1/8"-3/16" of the desired system thickness.
Topcoats Series 233, 237, 238, 239, 246, 247, 248, 252SC, 256, 280, 281, 282, 284, 285, 286, 290, 291, 294, 295, 296, 297. Note: These topcoats may only be used when recommended aggregate has been broadcast to refusal into the wet Series 241. Note: If Series 247 (tinted), 248 (tinted), 290, 291 or 297 is selected for the finish coat over a broadcast system, a grout coat of Series 237 or 238 (tinted), 256 (tinted), 280 or 281 is required. If Series 247 (clear), 248 (clear), 285, 294, 295 or 296 is selected for the finish coat over a broadcast system, a grout coat of 237 or 238 (clear), 256 (clear) or 284 is required.
Volume Solids 100% (mixed)
Recommended DFT 46.0 to 52.0 mils (1168 to 1320 microns) applied neat. Film thickness, after broadcasting with aggregate, is approximately 1/8". Refer to coverage rates table for more information. Note: Exceeding the recommended coating thickness may result in blistering of the product. Avoid excessive coating thickness by thoroughly filling voids, depressions and cracks with recommended filler or surfacer prior to Series 241 application.
Curing Time
TemperatureMin. RecoatLight TrafficPlace in Service
75°F (24°C)6 hours8 hours12 hours
For full resistance to chemicals and heavy traffic, 24 hour cure is needed. Curing time varies with surface temperature, air movement, humidity and film thickness. Note: For faster curing and low temperature applications, add No. 44-714 Ultra-Tread Accelerator, see separate product data sheet for cure information.
