A repositionable, self-adhesive wallpaper can be applied to a surface, positioned, repositioned, and can be removed without damaging the underlying surface, allowing the user to change wallpaper designs periodically. Embodiments comprise a vinyl sheet having front and rear surfaces, the front surface having a surface coating that is capable of having an image printed thereon; a removable backing layer comprising a clay coated kraft paper and a release agent; and a pressure sensitive adhesive disposed between the sheet rear surface and the backing layer, the adhesive being an acrylic emulsion adhesive applied to the rear surface, such that after the backing layer has been separated to expose the adhesive the surface covering can be applied to a surface, and the applied surface covering can be removed from the surface and the surface covering can be repositioned and/or reused.

1. A repositionable surface covering, comprising: a vinyl sheet having a front surface and a rear surface, the front surface further comprising a surface coating, the surface coating capable of having an image printed thereon;a removable backing layer comprising a paper and a release agent; anda pressure sensitive adhesive disposed between the sheet rear surface and the backing layer, the adhesive being an acrylic emulsion adhesive applied to the rear surface, wherein the adhesive is an acrylic emulsion adhesive characterized by an alkaline pH, a minimum application temperature of +20 degrees F., a service temperature range from 0 degrees F. to +150 degrees F., and regulatory compliances of FDA 21, CFR 175, 105, 176, 170, and 180 for incidental food contact, CONEG, Heavy Metals, ASTM 963a, and Child Toy Safety,such that after the backing layer has been separated to expose the adhesive the surface covering can be applied to a surface, and the applied surface covering can be removed from the surface and the surface covering can be repositioned and/or reused. 2. The repositionable surface covering as described in claim 1, wherein after removal from a surface, the removed repositionable surface covering can be reapplied to another surface. 3. The repositionable surface covering as described in claim 1, wherein after removal from a surface, the removed repositionable surface covering can be stored prior to being reused. 4. A repositionable wallpaper, comprising: a vinyl sheet having a front surface and a rear surface, the front surface further comprising a surface coating, the surface coating capable of having an image printed thereon;a removable backing layer comprising a clay coated kraft paper and a release agent; anda pressure sensitive adhesive disposed between the sheet rear surface and the backing layer, the adhesive being an acrylic emulsion adhesive that is applied to the rear surface, the adhesive being characterized by an alkaline pH, a minimum application temperature of +20 degrees F., a service temperature range from 0 degrees F. to +150 degrees F., and regulatory compliances of FDA 21, CFR 175, 105, 176, 170, and 180 for incidental food contact, CONEG, Heavy Metals, ASTM 963a, and Child Toy Safety;such that after the backing layer has been separated to expose the adhesive the surface covering can be applied to a surface, and the applied surface covering can be removed from the surface and the surface covering can be repositioned and/or reused, and wherein after removal from a surface, the adhesive layer of the removed repositionable surface covering can be covered with a liner to prevent self-adhesion.
