A composition for forming an acoustic texture material on a surface comprises a propellant material and acoustic texture material. The propellant material comprises di-methyl ethylene. The acoustic texture material comprises a coating portion comprising a base, a filler, and a binder and chips of chip material having a physical structure. When the propellant material and the acoustic texture material are mixed together, the propellant material does not substantially alter the physical structure of the chip material. |
