Particulate Materials for Acoustic Texture Material

Abstract

An acoustic texture material adapted to be dispensed from an aerosol assembly using bi-phase propellant materials to form a textured coating on drywall material such that the textured coating substantially matches a pre-existing acoustic texture material on the drywall material. The acoustic texture material has a base portion capable of existing in a flowable state and a hardened state and a particulate portion comprising discrete particles that are visible to an unaided eye. The particulate portion is comprised of at least one of urethane foam and melamine foam. The base portion is capable of securing the particles to the drywall material when the base portion is in the hardened state.

What is claimed is: 
     
         1 . An acoustic texture material adapted to be dispensed from an aerosol assembly using bi-phase propellant materials to form a textured coating on drywall material such that the textured coating substantially matches a pre-existing acoustic texture material on the drywall material, the acoustic texture material comprising:
 a base portion capable of existing in a flowable state and a hardened state; and   a particulate portion comprising discrete particles that are visible to an unaided eye; wherein   the particulate portion is comprised of at least one of urethane foam and melamine foam; and   the base portion is capable of securing the particles to the drywall material when the base portion is in the hardened state.   
     
     
         2 . An acoustic texture material as recited in  claim 1 , in which the particulate portion is formulated such that the bi-phase propellant materials do not dissolve the discrete, visible, irregular particles when the acoustic texture material is mixed with a liquid phase of the bi-phase propellant materials. 
     
     
         3 . An acoustic texture material as recited in  claim 1 , in which the particulate portion is distributed throughout the base portion when the base portion is in the flowable state and the acoustic texture material is stored within the aerosol assembly. 
     
     
         4 . A method of using an aerosol assembly to form a textured coating on a drywall material such that the textured coating substantially matches a pre-existing acoustic coating on the drywall material comprising the steps of:
 providing a base portion in a flowable state;   forming a particulate portion comprising discrete particles of at least one of urethane foam and melamine foam, where the discrete particles are visible to the unaided eye;   providing a bi-phase propellant material formulated not to dissolve the discrete particles;   arranging the base portion in the flowable state, the particulate portion, and the bi-phase propellant within the aerosol assembly;   operating the aerosol assembly such that a portion of the bi-phase propellant material forces the base portion in the flowable state and the particulate portion out of the aerosol assembly and onto the drywall material;   allowing the base portion to form a hardened state in which the base portion secures the discrete particles to the drywall material.   
     
     
         5 . A method as recited in  claim 4 , further comprising the step of formulating the particulate portion such that the bi-phase propellant materials do not dissolve the particles when the acoustic texture material is mixed with the bi-phase propellant materials. 
     
     
         6 . A method as recited in  claim 4 , further comprising the step of distributing the particulate portion throughout the base portion when the base portion is in the flowable state and the acoustic texture material is within the aerosol assembly.
