Method of producing a structure
View Patent ↗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.
1. A method of producing a structure, in which:
juxtaposing building elements so as to define a space between said building elements;
mixing a joint compound composition with water so as to obtain a joint compound;
filing said space with said joint compound composition, without using a tape; and
leaving said joint compound to harden,
wherein said joint compound composition comprises:
a) 50 to 60 wt % of calcium sulphate hemihydrate;
b) 5 to 15 wt % of an organic binder in powder form; and
c) 0.05 to 0.2 wt % of a water repellent selected from the group consisting of oleic acid, stearic acid and their alkali metal or alkaline-earth metal salts.
2. The method according to claim 1 , wherein the building elements are plasterboards coated with a paper facing.
3. The method according to claim 1 , wherein the joint compound composition further includes:
d) 1 to 10 wt % of a lightening agent.
4. The method according to claim 1 , wherein the joint compound composition comprises 5 to 10 wt % of the organic binder; 0.07 to 0.15 wt % of the water repellent; and 3 to 7 wt % of a lightening agent.
5. The method according to claim 1 , wherein in the joint compound composition the calcium sulphate hemihydrate is of the alpha type.
6. The method according to claim 1 , wherein in the joint compound composition the organic binder is selected from the group consisting of copolymers of vinyl esters and of ethylene monomers, polyacrylics, vinyl acetate/acrylic copolymers, styrene/acrylic and styrene/butadiene copolymers, vinyl acetate/vinyl versatate/acrylic and vinyl acetate/vinyl versatate/vinyl maleate terpolymers, acrylic terpolymers and blends thereof.
7. The method according to claim 3 , wherein in the joint compound composition the lightening agent is perlite.
8. The method according to claim 3 , wherein in the joint compound composition the lightening agent is non-water-repellent expanded perlite.
9. The method according to claim 1 , wherein the joint compound composition is in the form of a powder.
10. The method according to claim 1 , wherein the joint compound composition is in the form of a powder comprised of particles having a diameter of at most 200 microns.
