Abstract:
A method of repairing an acoustic ceiling material, the method comprising:storing a hardenable flowable substance utilizing a volatile organic compound (VOC) propellant for application to a patch surface surrounded by an acoustic ceiling material having an irregular surface texture in a fluid-tight dispensing container, the hardenable flowable substance comprising, a liquid base, a filler selected to form an extender or bodifier for the resulting patch material, an adhesive binder selected to adhere the resulting patch material to the surface, an aggregate comprising rubber particulates that does not decompose in the presence of VOC propellants, selected to give the resulting patch material an irregular surface texture, an anti-foaming agent, and a suspension agent, wherein the fluid-tight container has an actuator for selectively dispensing the hardenable flowable substance in the form of an aerosol spray; and dispensing selectively the hardenable flowable substance onto the patch surface such that the hardenable flowable substance forms a layer having a bumpy, irregular surface texture after being dispensed and curing which matches and is compatible with the acoustic ceiling material surrounding the patch.
