Abstract
A method for making a sound-insulating load-bearing floor, includes the following steps: applying a sound-insulating material over a load-bearing floor as to form a continuous coating layer; allowing the continuous coating layer to harden; applying a covering floor over said hardened continuous coating layer; 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: a first, component including at least one organic compound having at least one acid functional group or a derivative thereof, the first component having a Brookfield viscosity, measured at 23° C., of 0.1 Pa·s to 100 Pa·s, preferably 0.2 Pa·s to 50 Pa·s, more preferably 0.5 Pa·s to 20 Pa·s; and a second component including at least one metal oxide or hydroxide.
