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 suπounding the patch.
53. The method of repairing an acoustic ceiling material according to claim 52, wherein the hardenable flowable substance has the following composition by percentage weight: the liquid base of 20-70%>; the filler of 40-80%; the adhesive binder of 1-50%; the propellant of 5-20%; the aggregate of 2-40%>; the anti-foaming agent of 1-10%>; and the suspension agent of 1-20%.
54. The method of repairing an acoustic ceiling material according to claim 52, wherein: the liquid base consists essentially of water;
the filler consists essentially of a mixture of limestone and clay; the adhesive binder consists essentially of polyvinyl alcohol; the propellant consists essentially of dimethyl ether; the polyethylene particulates of the aggregate are open-cell; the anti-foaming agent consists essentially of Wichenol; and the suspension agent consists essentially of carbonal.
55. The method of repairing an acoustic ceiling material according to claim 52, wherein: the liquid base consists essentially of a solvent; the filler consists essentially of a mixture of limestone and clay; the adhesive binder consists essentially of polyvinyl alcohol; the propellant consists essentially of dimethyl ether; the polyethylene particulates of the aggregate are open-cell; the anti-foaming agent consists essentially of Wichenol; and the suspension agent consists essentially of carbonal.
56. The method of repairing an acoustic ceiling material according to claim 52, the hardenable flowable substance further comprising a fungicide.
57. The method of repairing an acoustic ceiling material according to claim 52, the hardenable flowable substance further comprising an anti-freeze.
58. The method of repairing an acoustic ceiling material according to claim 57, wherein the anti-freeze consists essentially of ethylene glycol.
59. The method of repairing an acoustic ceiling material according to claim 56, wherein the fungicide has a composition by percentage weight of 0.05-5%).
60. The method of repairing an acoustic ceiling material according to claim 57, wherein the anti-freeze has a composition by percentage weight of 1-10%.
