ABSTRACT:
An improved strippable glass fiber wall covering and process for its formation are provided. Initially, both sides of a glass fiber fabric are coated with a first coating applied from an aqueous dispersion of starch binder and polymeric latex binder. In a preferred embodiment a cross-linking agent and pigment also are present in the first aqueous dispersion. Following the drying of such dispersion to form a first coating on both surfaces, a second dried coating is provided on one side only that serves as a separation layer. The second coating is applied from an aqueous dispersion comprising paraffin and a rheology modifier. When applied to the wall in conventional manner, the separation layer facilitates the removal of the wall covering with ease when its time of usefulness is concluded.
