Abstract
A wallcovering comprising a paper ply (13) and plastics ply (10) laminated together and embossed after lamination has materials of the plies chosen so that inherent expansion of the paper ply when wetted is substantially wholly restrained by high resistance of the plastics ply to stretching without taking the plastics ply beyond its elastic limit so that the wallcovering does not bubble or pucker when the paper ply is wetted. Materials suitable for the plastics ply are foamed polystyrene and orientated polypropylene. A degree of fissuring of the plastics ply during embossing is acceptable and can aid porosity for drying.
