Patent ID: 7759416

Claim:
A method of producing a work, comprising juxtaposition of paper-faced plasterboards, optionally application of a tape, covering of the joint between the plasterboards by means of a drying compound applied by an airless technique, wherein the drying compound comprises, in percentages by weight relative to the total weight of the compound: 40 to 50% of a mineral filler having a diameter d 50 of between 10 and 15 microns; 5 to 10% of hydrophobic expanded perlite having a diameter d 50 of between 20 and 100 microns; 4 to 20% of a binder; 0.5 to 10% of a slip agent comprising a clay and/or talc and/or mica and/or a stearate; 1 to 15% of a water-retaining agent that is a cellulose derivative; and 1 to 15% of an antifoam agent, wherein the compound has an apparent density of between 1 and 1.25, and a Brookfield viscosity of the compound on leaving a spray nozzle is between 0.2 and 0.6 times an original Brookfield viscosity value of the compound.
