An aerosol texturing system for forming a textured surface on drywall material (22 fig.3). The aerosol texturing system comprises an aerosol assembly (30) defining a product chamber (40) and acoustic texture material (24) and propellant material (46) disposed within the product chamber (40) . The aerosol assembly is selectively operable in a first mode in which the product chamber (40) is sealed and in a second mode in which fluid is allowed to flow out of the product chamber (40) along a dispensing passageway. The acoustic texture material (24) comprises a base portion and a particulate portion. The particulate portion comprises at least one particulate material selected from the group consisting of urethane foam and melamine foam. At least a portion of the propellant material (46) exists in a gaseous state such that, when the aerosol assembly (30) is in the second mode, the propellant material (46) forces the acoustic texture material (24) out of the aerosol assembly (30) along the dispensing passageway. |
