Abstract
A paint mask dispensed onto a surface to be protected by finger application, or may be housed in and dispensed from a receptacle with a sponge or similarly porous and flexible tip. The paint mask permits immediate and convenient use by application to the surface of glass or other base to be protected from inadvertent paint, especially window frames and mullions, while prohibiting paint to affix itself to window glass. The painter may spread the mask onto the surface by means of the pad on one's finger, or may conveniently grip the paint mask applicator and drag the tool end of the dispenser onto targeted areas of the surface to be protected. The mask forms a skin onto which paint, varnish, or other coating material may have adhered or contacted and which resides upon a lubricated layer such that it may be slid, wiped, rinsed or peeled away. The need for razor blades or other hard or sharp instruments is avoided.
