Patent ID: 8784942

Claim:
A system for dispensing texture material in a desired spray pattern that substantially matches an existing texture pattern on a target surface, comprising: an aerosol dispenser comprising a container assembly defining an inner surface, where the inner surface defines a main chamber; and is at least in part a tin-plated steel, an actuator assembly defining an outlet opening having a cross-sectional area, where the cross-sectional area of the outlet opening is adjustable; a concentrate comprising a solvent/carrier comprising water, wall texture material, a first anti-corrosion material, where the first anti-corrosion material is a phosphate ester and comprises approximately 0.1-5.0% by weight of the concentrate, and a second anti-corrosion material, where the second anti-corrosion material is sodium nitrite and comprises approximately 0.25-2.00% by weight of the concentrate; and a propellant material; wherein the concentrate and propellant material are disposed within the container assembly such that the water is exposed to the inner surface of the container assembly; at least one of the first and second anti-corrosion materials forms a film on the inner surface of the container assembly; the film inhibits corrosion of the inner surface of the container assembly; and the cross-sectional area of the outlet opening is adjusted such that the propellant material forces the concentrate out of the outlet opening in a spray pattern that forms the desired texture pattern on the target surface.
