  • Patent number: 7047701
    Abstract: A jointing compound or plaster for construction elements, particularly paper-faced plasterboards. This plaster includes, in percentages by weight with respect to the total weight of plaster 50 to 85% of a mineral filler; 1 to 20% of an organic binder dispersible in an aqueous phase; 1 to 15% of a silicate-based agent other than the mineral filler; 0.2 to 5% of a hydrophobic agent which is a silicone derivative; 0.05 to 5% of polyvinyl alcohol; and water to make up to 100%. A method of producing a work such as a partition, a wall covering or a ceiling is also disclosed.
