BIRSS Stounpol binder — polyurethane binder for stone chippings
Two-component polyurethane binder for seamless outdoor granite-chip coatings on concrete, asphalt and metal.

Ultrapol 100 is an unpigmented epoxy binder that works together with the graded quartz sands “BIRSS Napolnitel Ultrapol” (Ultrapol filler), so the colour of the coating is set by the filler itself. The result is a dense floor for chemical and food production, garages, car washes, covered car parks and warehouses, including non-slip and watertight versions. Compressive strength is 100 MPa, flexural strength more than 35 MPa, service temperature up to +110 °C.
