Abstract
An acoustic ceiling patch or textured material in the form of a sprayable composition including a base, a filler and a binder as well as a propellant or carrier storable and dispensable from a pressurized dispenser having a delivery nozzle and a removable dispensing tube. An aerosol system with a spray nozzle is included on the container for selective discharge of the textured material onto a prepared patch area which may be on a drywall or support panel so as to match and blend with the surrounding acoustic ceiling surface area in order to provide a continuous and unbroken coextensive surface texture of mechanically and visually matched material. A distribution straw is included for selectively conducting the textured material in a desired direction while holding the dispenser upright.
Claims6
A method for forming a layer of textured patch material on a surface comprising the steps of:
- storing a hardenable, flowable substance for application to a patch surface surrounded by an acoustic ceiling material having an irregular Surface texture in a fluid-tight dispensing container, said hardenable, flowable substance comprising a mixture of a liquid base substance, a filler substance of a material selected to form a binder or bodifier for the resulting patch material, an adhesive binder of a material selected to adhere the resulting patch material to the surface, a propellant and at least one of an aggregate selected to give the resulting patch material an irregular surface texture, a blowing agent and an expandable material selected to provide tensile strength for the resulting patch material wherein said fluid-tight container has means for selectively dispensing said hardenable, flowable substance in the form of an aerosol spray;
- and
- selectively dispensing the hardenable, flowable substance onto the patch surface such that the hardenable flowable substance forms a bumpy, irregular surface texture after being dispensed and curing which matches and is compatible with the acoustic ceiling material surrounding the patch.
