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.
Colors 00GR Gray, 00RD Red. Aromatic urethanes chalk and yellow with age, extended exposure to UV and artificial lighting. Note: Colored quartz may be broadcast into the system, creating a multi-colored or tweed look. Tnemec provides standard 222 Q colors, however, due to the pigmented background of the 245, a variance in color may be noticeable. A sample is recommended for color selection.
Finish Matte
Note: For textured finish, purchase either clean, dry, 30/50 mesh silica sand or other approved aggregates with an optional (lock) coat of Series 246, Series 280 or Series 282. Tnemec ChromaQuartz or approved equal can be substituted for decorative quartz application with an optional (lock) coat of Series 284 or Series 286 when a clear coat is desired.
