Beschreibung
Zusammenfassung:	The invention relates to a method for producing a polyurethane flooring (129) for a sports field (136), the method comprising: - providing (502) reactive components for producing polyurethane, the reactive components comprising an A component (902) being a polyol mixture and a B component (904) being an isocyanate mixture and water (914), the B component comprising: o 2,2' Methyiendiphenyldiisocyanate (922); o diphenylmethane-2,4'-diisocyanate (924); o diphenylmethane-4,4'-diisocyanate (926); and o isocyanate prepolymer (932); - mixing (504) the reactive components for generating a liquid polyurethane reaction mixture (129); - applying (506) the polyurethane reaction mixture (128) to a ground (103) of the sports field before chemical reactions in the reaction mixture have generated a solid polyurethane foam, the polyurethane foam after its solidification to be used as the polyurethane flooring.
