A nozzle assembly through which texture material is dispensed from an aerosol system to substantially match an existing texture pattern. The nozzle assembly comprises an actuator member, at least one outlet member, and an outlet structure. The actuator member has a stem portion adapted to engage the aerosol system, an actuator opening, and an actuator passageway for allowing fluid to flow between the stem portion and the actuator opening. The at least one outlet member defines at least one outlet opening. The outlet structure secures the at least one outlet member to the actuator member. The at least one outlet member may be configured such that the outlet opening defines a plurality of cross-sectional areas each corresponding to a predetermined texture pattern. One of the cross-sectional areas is a selected cross-sectional area. The predetermined texture pattern associated with the selected cross-sectional area substantially matches the existing texture pattern. The outlet structure allows the at least one outlet member to be configured such that the fluid flows through the actuator passageway, the outlet passageway, and the outlet opening.
