<p>A coating composition has a natural fibre-bearing dry matter mixture, as well as cellular plastic grains, mixed into water. By spreading this composition onto any base, particularly by spraying, and by hardening it, particularly through drying, the coating is formed from the coating composition, which coating provides extremely good acoustic properties. If a special fibre base plate based on chemical pulp is used as the base of the coating, the plate-like acoustic element is obtained.</p> |
