Abstract:
1. A hardenable flowable substance for application to a patch surface surrounded by an acoustic ceiling material having an irregular surface texture to form a layer of textured patch material on the patch surface, wherein the hardenable flowable substance is storable in a fluid-tight dispensing container, and further wherein the hardenable flowable substance is mixed with a volatile organic compound propellant, 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, selected to give the resulting patch material an irregular surface texture that substantially matches the surrounding acoustic ceiling material; an anti-foaming agent; and a suspension agent comprising carbonal, wherein the hardenable flowable substance is initially stored in the fluid state and is dispensable in the form of a controllable aerosol spray from the fluid-tight container and, after being released and curing, forms a bumpy, irregular surface texture that matches and is compatible with the acoustic ceiling material surrounding the patch, and wherein the aggregate and volatile organic compound propellant are selected such that the aggregate does not decompose in the volatile organic compound propellant when stored in the fluid state or dispensed in the aerosol spray.
