Series 245
Ultra-Tread S
Generic Type
Polyurethane Modified Concrete
Common Usage
Ultra-Tread S is a low odor, slurry applied, flowable mortar 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).

Surfacer/Filler/Patcher
Series 242 (extended with aggregate) or Series 243, 244. 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 or 208 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.
Topcoats
Series N222, 230ESD, 233, 237, 238, 239, 246, 247, 248, 249ESD, 252SC, 256, 257, 280, 280FC, 281, 282, N284, N285, 286, V290, 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 grinding prior to topcoating. Note: If Series 247 (tinted), 248 (tinted), V290, or 297 is selected for the finish coat over a broadcast system, a grout coat of Series N222, 233, 237 or 238 (tinted), 256 (tinted), 257 (tinted), 280, 281 or N284 is required. If Series 247 (clear), 248 (clear), N285, or 296 is selected for the finish coat over a broadcast system, a grout coat of 237 or 238 (clear), 256 (clear), 257 (clear), or N284 is required.
Curing Time
| Temperature | Min. Recoat | Light Traffic | Place In Service † |
|---|---|---|---|
| 75°F (24°C) | 6 hours | 8 hours | 12 hours |
† For full resistance to chemicals and steam cleaning, 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.
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.

Series N222, 233, 237, 238, 239, 252SC, 256, 257. 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 or 4 to 5 sq ft per pound and decorative flake at an approximate rate of 0.25 lb per sq ft. The Series 245 base coat will account for approximately 1/8"-3/16" of the desired system thickness.
