Series 245 | Ultra-Tread S

Generic Type Polyurethane Modified Concrete
Common Usage Ultra-Tread S is a low odor, slurry applied floor topping designed for monolithic applications in abusive service areas. It provides superior performance to other flooring systems such as acid brick, quarry tile and most polymer flooring systems. Designed for use in food and beverage facilities, pharmaceutical and processing areas, commercial and restaurant kitchens or anywhere a durable floor topping is required. Provides excellent chemical resistance and withstands thermal shock due to hot liquids and aggressive cleaning procedures. Areas may be quickly returned to service within hours of installation, depending on temperature and humidity. Ultra-Tread S is a 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 mortar system is typically applied by trowel or screed, backrolled with a loop roller and broadcast to refusal with 30/50 mesh aggregate, colored quartz or decorative flake. Note: Series 245 can be applied as a stand-alone mortar. If topcoating, the mortar, while still wet, must be broadcast to refusal with aggregate, color quartz or decorative flake typically completed within 10 to 15 minutes of application. Color quartz and/or decorative flake systems will require an additional broadcast layer using Series 222, 224, 237, 238 or 256 clear to obtain a uniform appearance and texture before applying the desired clear finish coats. This will typically result in a total system thickness of 1/4"-5/16".
Colors 00GR Gray, 00RD Red. Black, blue, beige, and green are also available. Additional lead time may apply. Aromatic urethanes chalk and yellow with age, extended exposure to UV and artificial lighting. Note: Colored quartz or decorative flake may be broadcast to refusal into the system, creating a multi-colored or tweed look. A variance in color may be noticeable and require a second broadcast layer of colored quartz or decorative flake. A sample is recommended for color selection.
Finish Matte
Surfacer/Filler/Patcher Series 243, 244 or Series 245 (extended with aggregate). Patching should be allowed to cure a minimum of six hours prior to placement of the Series 245 to avoid blistering or doming of the Series 245. Series 215, or 201 mixed with fumed silica, may be used for small patches or crack repairs. Certain high-early strength, cementitious repair mortars are also acceptable. Contact Tnemec for further qualifications.
Primers Self-priming
Intermediate Series 222, 223, 224, 237, 238, 239, 252SC, 256. Note: Series 245 must be broadcast to refusal with aggregate, colored quartz or decorative flake if topcoating. Broadcast aggregate or colored quartz at an approximate rate of 0.5 lb per sq ft and decorative flake at an approximate rate of 0.25 lb per sq ft. The Series 245 base coat will account for approximately 1/4" of the desired system thickness.
Topcoats Series 237, 238, 239, 246, 247, 248, 252SC, 256, 280, 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 245 or the cured surface of the Series 245 has been cleaned and thoroughly abraded by sanding or grinding prior to topcoating. 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 3/16" to 1/4" (5 mm to 6 mm). Series 245 can be applied as a stand alone mortar (neat) at 3/16"-1/4" (5 mm - 6 mm). Broadcasting with aggregate to refusal at 3/16" (5 mm) neat will yield a total thickness of 1/4" (6 mm), at 1/4" (6 mm) neat will yield a total thickness of 5/16" (8 mm). Important: Series 245 should not exceed 1/2" (13 mm) thickness when applied neat. 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 245 application.
