Particulate materials for acoustic texture material
View Patent ↗A composition for forming a textured coating on drywall material, where the textured coating substantially matches a pre-existing acoustic texture material on the drywall material, comprises acoustic texture material and propellant material. The acoustic texture material comprises a base portion the base portion is capable of existing in a flowable state and a hardened state, and a particulate portion the particulate portion comprises discrete, visible particles of solidified urethane foam having irregular shapes. The propellant material comprises a hydrocarbon propellant. The particles of urethane foam are distributed throughout the acoustic texture material when the base portion is in the flowable state. The irregular shapes of the particulate portion are substantially the same when the base portion is in the flowable state and in the hardened state. The base portion is capable of securing the discrete, visible, particles of solidified urethane foam to the drywall material when the base portion is in the hardened state.
1. A composition for forming a textured coating on drywall material, where the textured coating substantially matches a pre-existing acoustic texture material on the drywall material, comprising:
acoustic texture material comprising
a base portion the base portion is capable of existing in a flowable state and a hardened state, and
a particulate portion the particulate portion comprises discrete, visible particles of solidified urethane foam having irregular shapes
propellant material comprising a hydrocarbon propellant; wherein
the particles of urethane foam are distributed throughout the acoustic texture material when the base portion is in the flowable state;
the irregular shapes of the particulate portion are substantially the same when the base portion is in the flowable state and in the hardened state; and
the base portion is capable of securing the discrete, visible, particles of solidified urethane foam to the drywall material when the base portion is in the hardened state.
2. A composition as recited in claim 1 , in which the hydrocarbon propellant is DME.
3. A method of forming a textured coating on drywall material such that the textured coating substantially matches a pre-existing acoustic texture material on the drywall material, comprising the steps of:
providing acoustic texture material comprising
a base portion capable of existing in a flowable state and a hardened state, and
a particulate portion comprising discrete, visible particles of solidified urethane foam having irregular shapes;
arranging within an aerosol assembly the acoustic texture material such that the particles of urethane foam are distributed throughout the base portion when the base portion is in the flowable state;
arranging within the aerosol assembly propellant material comprising a hydrocarbon propellant; and
operating the aerosol assembly such that
the propellant material forces the acoustic texture material out of the aerosol assembly and onto the drywall material, and
the base portion changes to the hardened state such that the discrete, visible, particles of solidified urethane are secured to the drywall material.
4. A method as recited in claim 3 , in which the hydrocarbon propellant is DME.
5. A method as recited in claim 3 , in which the irregular shapes of the urethane foam particles are substantially the same when the base portion of the acoustic texture material is in the flowable state and in the hardened state.
