A system for dispensing texture material in a desired spray pattern that substantially matches an existing texture pattern on a target surface has a container assembly, an actuator assembly, and a concentrate comprising a solvent/carrier comprising water, wall texture material comprising at least one filler and a resin/binder, a first anti-corrosion material, where the first anti-corrosion material is a phosphate ester, and a second anti-corrosion material, where the second anti-corrosion material is sodium nitrite. At least one of the first and second anti-corrosion materials forms a film on the inner surface of the container assembly while the concentrate is stored within the container assembly. The film inhibits corrosion of the corrodible material forming at least part of the inner surface of the container assembly. The first and second anti-corrosion materials together comprise 0.125-7.00% by weight of the concentrate.
