The present invention relates to a method for making a sound-insulating load-bearing floor, said method comprising the following steps: - providing a load-bearing floor; - applying a sound-insulating material onto said load-bearing floor so as to form a substantially continuous coating layer; allowing said substantially continuous coating layer to dry; wherein said sound-insulating material includes: from 40% by weight to 95% by weight, preferably from 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; from 5% by weight to 60% by weight, preferably from 10% by weight to 40% 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 (Tg) of from -50°C to +50°C, preferably of from -40°C to + 10°C.
