Abstract
A wall covering, a method of producing it and a method of covering a wall. The wall covering comprises a planar substrate, such as a nonwoven base substrate, having a front, and a back facing opposite the front. There is a barrier layer on the back of the substrate and an adhesive layer superimposed on the barrier layer. The adhesive layer comprises a first polymer component, a second polymer component, the first polymer component being a non crosslinked polymer and said second polymer component being a crosslinked polymer exhibiting properties of superabsorbency. The adhesive exhibits when exposed to water, a strength sufficient for binding to a wall substrate and a glide resistance low enough for allowing repositioning of the wall cover by sliding the wallcover on the wall without having to lift it up over a period of time of at least 5 minutes.
