Sherwin-Williams Poly-Crete MD

Poly-Crete is Sherwin-Williams High Performance Flooring’s cementitious urethane line: seamless industrial floors that combine urethane resin with cement and aggregate for thermal-shock, chemical, and moisture performance epoxy cannot match. The family spans smooth self-leveling grades (SL, MD), broadcast slip-resistant systems (SLB, MDB), and heavy trowel-applied mortar (HF). It came to Sherwin-Williams with the Dur-A-Flex acquisition on July 1, 2022, keeping its product names and formulations. Poly-Crete floors serve food and beverage plants, kitchens, breweries, cold storage, and chemical-exposure manufacturing. Every grade shares the core chemistry. Thickness, texture, and finish are what the grade letters distinguish. Craftsman Concrete Floors installs the full Poly-Crete line nationwide and matches the grade to the floor’s actual service.

Poly-Crete MD serves bottling areas, warehouses, and industrial production floors that want a self-leveling urethane cement without a broadcast texture or a separate topcoat. The uniform matte finish suits facilities where appearance and cleanability both matter, such as beverage plants, packaging halls, and light-process manufacturing. It handles thermal cycling and wet-dry swings that delaminate epoxy in the same service. Do not apply it over unreinforced sand-cement screeds, asphalt, glazed tile, or metal substrates. Sound profiled concrete is the base. Where the same build needs slip texture, MDB adds quartz broadcast and topcoat options to the identical body. Craftsman Concrete Floors installs MD with the perimeter keying and joint detailing the installation guidelines specify.

No. Poly-Crete MD is engineered to serve as its own wearing surface, which removes a coat, a cure window, and a future recoat cycle from the floor’s life. Fewer installation stages, faster return to service, and no topcoat film to wear through and renew. The trade-off is finish options. Where a project wants UV color stability or a specific sheen, the MDB build takes Poly-Crete Color-Fast or TF Plus topcoats. Note that aromatic urethane cements amber under UV exposure without affecting performance, which matters only where daylight hits the floor and color is critical. The matte, uniform-color surface reads clean and hides traffic patterning well. Craftsman Concrete Floors specifies MD bare or steps to MDB-with-topcoat when the finish requirements justify the added system.
