An aerosol system for dispensing texture material on a horizontal surface comprising an aerosol assembly, an actuator member, and an outlet structure. The aerosol assembly, which is adapted to contain and dispense texture material, defines a container axis that is substantially vertical during normal use. The actuator member comprises a valve stem for engaging the aerosol assembly and defines a first portion of a dispensing path. The outlet structure defines a second portion of the dispensing path, an outlet orifice, and a dispensing axis. The outlet structure is arranged adjacent to the actuator member such that fluid flowing along the first portion of the dispensing path flows through the second portion of the dispensing path and the outlet orifice and generally along the dispensing axis. The dispensing axis is substantially aligned with the container axis. A cross-sectional area of the outlet orifice is adjustable.
