PROBLEM TO BE SOLVED: To provide a floor laying method capable of preventing the generation of a tacking sound even when it is cold and joining a floor covering material and a floor substrate material together with favorable workability. SOLUTION: In the floor laying method using a pressure sensitive adhesive double coated tape, on the backside of the floor covering material 3, there is stuck the surface of one adhesive layer 12 of an adhesive double coated sheet 1 wherein the adhesive layers are installed in both surfaces of a synthetic resin foam, and the surface of the other adhesive layer 11 is stuck on that of the floor substrate material for the purpose of joining the covering material 3 and the substrate material together. The glass transition temperature of at least either of the adhesive layers is taken as -10 deg.C or below and preferably taken as -20 deg.C or below.
