Producing a structure, in which: building elements are juxtaposed so as to define a space between said building elements; a joint compound composition is mixed with water so as to obtain a joint compound; said space is filled with said joint compound composition, without using a tape; and said joint compound is left to harden, wherein said joint compound composition includes: a) 50 to 60% of calcium sulphate hemihydrate; b) 5 to 15% of an organic binder in powder form; and c) 0.05 to 0.2% of a water repellent selected from the group consisting of oleic acid, stearic acid and their alkali metal or alkaline-earth metal salts.

Method of producing a structure

The present invention relates to a joint compound composition for building elements, particularly paper-faced plasterboards. This composition comprises: The invention also relates to a method producing a structure, such as a partition, a wall trim or a ceiling. According to this method:

Joint compound composition for building elements and method of producing a structure

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.
