An aerosol device for dispensing texture material for matching existing acoustical ceiling texture. The device comprises a container, a valve assembly, a dispensing nozzle, a hardenable material, and pressurized inert gas as a propelling mechanism. The hardenable material and pressurized inert gas are placed into the container. When the valve assembly is opened, the inert gas forces the hardenable material out of the container through the dispensing nozzle. The dispensing nozzle diverts at least a portion of the hardenable material exiting the container to develop a spray suitable for the application of the hardenable material onto the ceiling surface being textured. The hardenable material preferably comprises at least water, filler, binder, and polystyrene particles. The inert gas is preferably nitrogen.

What is claimed: 1. A texturing system for applying a hardenable acoustic texture material to a surface comprising: a container assembly defining a container chamber; acoustic texture material arranged within the container chamber; propellant material arranged within the container chamber to pressurize the acoustic texture material; a housing supported within the container chamber, where the housing defines a housing chamber defining a housing inlet, where the housing inlet is configured such that the pressurized acoustic texture material is arranged within the housing chamber; a valve stem defining an inlet opening and an outlet opening, where the valve stem is supported for movement from a first valve stem position, through an intermediate valve stem position, and into a second valve stem position; a seal member that supports the valve stem relative to the container assembly; and a metering member supported relative to the valve stem within the housing chamber for movement between a first metering member position relative to the valve stem and a second metering member position relative to the valve stem; wherein when the valve stem is in the first valve stem position, the metering member engages the seal member to prevent fluid flow out of the container chamber by covering the inlet opening of the valve stem; when the valve stem is in the intermediate valve stem position and the metering member is in the first metering member position, pressurized texture material within the housing chamber flows into the inlet opening of the valve stem; and when the valve stem is in the second valve stem position and the metering member is in the second metering member position, the metering member engages the valve stem to prevent fluid flow out of the container chamber by covering the inlet opening of the valve stem. 2. A texturing system as recited in claim 1, in which the housing engages the metering member to guide the metering member for movement between the first metering member position and the second metering member position. 3. A texturing system as recited in claim 1, in which at least one guide flange extends from the housing, where the at least one guide flange engages the metering member to guide the metering member for movement between the first metering member position and the second metering member position. 4. A texturing system as recited in claim 1, in which the housing engages the valve stem to guide the stem member for movement between the first valve stem position and the second valve stem position. 5. A texturing system as recited in claim 1, in which at least one guide flange extends from the housing, where the at least one guide flange engages the valve stem to guide the valve stem for movement between the first valve stem position and the second valve stem position. 6. A texturing system as recited in claim 1, in which: the metering member frictionally engages the valve stem such that the metering member moves with the valve stem as the valve stem moves through the intermediate valve stem position; and the metering member engages the housing such that the metering member no longer moves with the valve stem as the valve stem moves into the second valve stem position. 7. A texturing system as recited in claim 1, in which: a release projection is formed on one of the metering member and the valve stem; and a release groove is formed on the other of the metering member and the valve stem; wherein the release groove receives the release projection such that the metering member moves with the valve stem as the valve stem moves through the intermediate valve stem position; and the metering member engages the housing such that the release projection is not received by the release groove as the valve stem moves into the second valve stem position, where the metering member no longer moves with the valve stem when the release projection is not received by the release groove. 8. A method of applying a hardenable acoustic texture material to a surface comprising: providing a container assembly defining a container chamber; arranging acoustic texture material within the container chamber; pressurizing the acoustic texture material by arranging propellant material within the container chamber; supporting a housing within the container chamber such that the housing defines a housing chamber defining a housing inlet; configuring the housing inlet such that the pressurized acoustic texture material is arranged within the housing chamber; providing a valve stem defining an inlet opening and an outlet opening; providing a seal member; arranging the seal member to support the valve stem for movement, relative to the container assembly, from a first valve stem position, through an intermediate valve stem position, and into a second valve stem position; and supporting a metering member relative to the valve stem within the housing chamber for movement between a first metering member position relative to the valve stem and a second metering member position relative to the valve stem; when the valve stem is in the first valve stem position, causing the metering member to engage the seal member to prevent fluid flow out of the container chamber by covering the inlet opening of the valve stem; when the valve stem is in the intermediate valve stem position and the metering member is in the first metering member position, allowing pressurized texture material within the housing chamber to flow into the inlet opening of the valve stem; and when the valve stem is in the second valve stem position and the metering member is in the second metering member position, causing the metering member to engage the valve stem to prevent fluid flow out of the container chamber by covering the inlet opening of the valve stem. 9. A method as recited in claim 8, further comprising the step of causing the housing to engage the metering member to guide the metering member for movement between the first metering member position and the second metering member position. 10. A method as recited in claim 8, further comprising the step of providing at least one guide flange that extends from the housing, where the at least one guide flange engages the metering member to guide the metering member for movement between the first metering member position and the second metering member position. 11. A method as recited in claim 8, further comprising the step of causing the housing to engage the valve stem to guide the valve stem for movement between the first valve stem position and the second valve stem position. 12. A method as recited in claim 8, further comprising the step of providing at least one guide flange that extends from the housing, where the at least one guide flange engages the valve stem to guide the valve stem for movement between the first valve stem position and the second valve stem position. 13.
