Abstract
A method for making a sound-insulating load-bearing floor, includes the following steps: providing a load-bearing floor; applying a sound-insulating material onto the load-bearing floor so as to form a substantially continuous coating layer; allowing the substantially continuous coating layer to dry; wherein the sound-insulating material includes: 40% by weight to 95% by weight, preferably 60% by weight to 90% by weight, with respect to the total weight of the sound-insulating material, of at least one rubber in a subdivided form; 5% by weight to 60% by weight, preferably 10% by weight to 40% by weight, with respect to the total weight of the sound-insulating material, of at least one binding agent including at least one water-dispersible polymer having a glass transition temperature (Tg) of −50° C. to +50° C., preferably of −40° C. to +10° C.
