Abstract

Abstract A unitary strippable stencil having an upper layer of thin, flexible, sheet material raised to a substantial height, above the surface to be stencilled by a relatively thick, resilient, compressible, distortable lower layer, which accommodates itself to a rough, or ribbed, surface. Those letters and numerals which have islands, have the islands connected by integral, narrow ''''bridges'''' at stencil height so that paint spray may pass thereunder. The stencil includes integral, down-turned flanges encompassing the upper part of the high walls of the compressible layer and includes a pressure sensitive adhesive coating which holds the underface of the thick resilient lower layer in place. The resilient layer may be a polymeric foam.
