Abstract (en)

[origin: WO2023285424A1] The present invention relates to a method for producing a floor construction on a substrate by applying a screed to the substrate and then applying a seal to the screed. The screed is based on a screed composition which comprises an aluminate binder, a calcium sulfate binder and fillers, where the amount of filler is 30 to 80 wt% and the total amount of aluminate binder and calcium sulfate binder is 20 to 70 wt% and the weight ratio of aluminate binder to calcium sulfate binder is in the range from 1:1 to 1:5. The method enables a short production time and at the same time improved adhesion between screed and seal.
