Claim:
A method for making a sound-insulating load-bearing floor, comprising: providing a load-bearing floor; applying a sound-insulating material onto said load-bearing floor so as to form a substantially continuous coating layer; and allowing said substantially continuous coating layer to dry; wherein said sound-insulating material comprises: 40% by weight to 95% by weight, with respect to the total weight of the sound-insulating material, of at least one rubber in a subdivided form; and 5% by weight to 60% by weight, with respect to the total weight of the sound-insulating material, of at least one binding agent comprising at least one water-dispersible polymer having a glass transition temperature (T g ) of âˆ’50Â° C. to +50Â° C. and wherein said sound-insulating material has, in a dry form, a dynamic stiffness, measured according to standard ISO 9052-1:1989, lower than 150 MN/m 3 .
