Abstract
A method for applying a spray texture material to a wall surface utilizing an aerosol container for the texture material, along with discharge tubes through which the material is dispensed. By using tubes of different cross-sectional area, the spray patterns of the material can be made with smaller and larger particle size within more precisely controlled limits.

A method of applying a hardenable liquid texture material as a spray onto a surface area to form a textured surface of a predetermined spray pattern, said method comprising:
- a. providing an aerosol texture material dispensing apparatus which has a material containing portion containing said texture material and a discharge nozzle means and which is adapted to discharge said liquid material under pressure from said containing portion and through said nozzle means;
- b. providing a plurality of dispensing tube means, each defining an elongate dispensing passageway having an inlet and an outlet, with the passageways of the plurality of tube means each having different cross sections to obtain differing spray texture patterns, and selecting one of said tube means and locating the inlet of said selected dispensing tube means adjacent to said discharge nozzle means so that the liquid texture material is able to flow from the discharge nozzle means into the inlet of said tube means and through said dispensing passageway;
- c. positioning the apparatus with said selected dispensing tube means spaced from said surface area so that the outlet of the dispensing tube means is directed toward said surface area and spaced therefrom;
- d. causing said liquid texture material to be delivered by said apparatus under pressure from said nozzle means and into said selected dispensing tube passageway to be discharged from the outlet of the tube means as a spray that is deposited on said surface area as said predetermined pattern, with said texture material on said surface area hardening to form said textured surface.
An assembly for applying a hardenable liquid texture material as a spray onto a surface area to form a textured surface of a predetermined spray pattern, said assembly comprising:
- a. an aerosol texture material dispensing apparatus which has a material containing portion containing said texture material and a discharge nozzle means and which is adapted to discharge said liquid material under pressure from said containing portion and through said nozzle means;
- b. a plurality of dispensing tubes means, each defining an elongate dispensing passageway having an inlet and an outlet, with the passageways of the plurality of tube means each having different cross sections to obtain differing spray texture patterns, and said apparatus and the dispensing tube means being arranged so that the inlet of a selected one of said dispensing tube means is capable of being positioned adjacent to said discharge nozzle means so that the liquid texture material from the discharge nozzle means flows into the inlet of said tube means and through said dispensing passageway;
- c. the assembly being characterized in that with said selected one of said dispensing tube means mounted to the apparatus and being spaced from said surface area so that the outlet of the dispensing tube means is directed toward said surface area and spaced therefrom, and with the apparatus being operated so that said liquid texture material is delivered by said apparatus under pressure from said nozzle means and into said dispensing tube passageway to be discharged from the outlet of the tube means as a spray, said texture material is deposited on said surface area as said predetermined spray pattern to harden to form said textured surface.
