Aerosol dispensing systems and methods and compositions for repairing interior structure surfaces

1. A composition for covering an anomaly in a wall substantially to match a pre-existing texture pattern surrounding the anomaly, the composition being adapted to be dispensed from an aerosol assembly operable in closed and open configurations, comprising:

wall material concentrate comprising:

28.0-38.0% by weight of a solvent/carrier comprising water,

3.0-4.5% by weight of a resin/binder,

57.4-64.8% by weight of filler material, and

0.5-3.0% by weight of thickener material; and

propellant material; wherein

the propellant material is combined with the wall material concentrate within the aerosol assembly to form a contained material;

the propellant material comprises substantially within 5-20% by weight of the contained material;

when the aerosol assembly is operated in the open configuration, the propellant material forces the contained material out of the aerosol assembly and onto the surface; and

a first portion of the contained material on the surface is worked to form a base coat that covers the anomaly; and

a second portion of the contained material on the surface is applied in a desired texture pattern on the base coat such that the desired texture pattern substantially matches the pre-existing texture pattern.

2. A composition as recited in claim 1 , in which the wall material concentrate comprises:

31.5-34.0% by weight of a solvent/carrier comprising water;

3.0-4.5% by weight of a resin/binder; and

57.4-64.8% by weight of filler material.

3. A composition as recited in claim 1 , in which the propellant material comprises substantially within 7.5-12.5% by weight of the contained material.

4. A composition as recited in claim 2 , in which the propellant material comprises substantially within 7.5-12.5% by weight of the contained material.

5. A method of covering an anomaly in a wall substantially to match a pre-existing texture pattern surrounding the anomaly, the composition adapted being to be dispensed from an aerosol assembly operable in closed and open configurations, comprising:

providing a wall material concentrate comprising

28.0-38.0% by weight of a solvent/carrier comprising water,

3.0-4.5% by weight of a resin/binder, and

57.4-64.8% by weight of filler material, and

0.5-3.0% by weight of thickener material; and

providing propellant material;

combining the propellant material with the wall material concentrate within the aerosol assembly to form a contained material such that the propellant material comprises substantially within 5-20% by weight of the contained material;

operating the aerosol assembly in the open configuration such that the propellant material forces the a first portion of the contained material out of the aerosol assembly and onto the surface;

working the first portion of the contained material on the surface to form a base coat that covers the anomaly;

operating the aerosol assembly in the open configuration such that the propellant material forces a second portion of the contained material out of the aerosol assembly and onto the base coat to form a repaired surface, where the repaired surface substantially matches the pre-existing texture pattern.

6. A method as recited in claim 5 , in which the wall material concentrate comprises:

31.5-34.0% by weight of a solvent/carrier comprising water;

3.0-4.5% by weight of a resin/binder; and

57.4-64.8% by weight of filler material.

7. A method as recited in claim 5 , in which the propellant material comprises substantially within 7.5-12.5% by weight of the contained material.

8. A method as recited in claim 6 , in which the propellant material comprises substantially within 7.5-12.5% by weight of the contained material.

9. A method as recited in claim 5 , further comprising the step of arranging a substrate member over at least a portion of the anomaly prior to the step of applying the first portion of the contained material to the anomaly.

10. A method as recited in claim 9 , in which:

the anomaly is a joint between adjacent drywall sheets; and

the substrate member is drywall tape.

11. A method as recited in claim 9 , in which:

the anomaly is a hole in a drywall sheet; and

the substrate member is patch member.

12. A composition as recited in claim 1 , in which the wall material concentrate comprises from 0.5-2.0% by weight of the thickening material.

13. A composition as recited in claim 1 , in which the thickening material comprises thickening clay.

14. A composition as recited in claim 1 , in which the thickening material comprises from 1.2-1.5% by weight of the thickening material.

15. A composition as recited in claim 1 , in which the thickening material of the wall material concentrate comprises:

from 0.5-2.0% by weight of a first thickening material; and

from 0.0-1.0% by weight of a second thickening material.

16. A composition as recited in claim 1 , in which the thickening material of the wall material concentrate comprises:

a first thickening material comprising a thickening clay; and

a second thickening material comprising a shear-sensitive thickener.

17. A composition as recited in claim 1 , in which the thickening material of the wall material concentrate comprises:

from 1.2-1.5% by weight of a first thickening material; and

from 0.0-0.4% by weight of a second thickening material.
