ABSTRACT:
Disclosed is decorative surface covering that has a substantially non-aqueous absorptive layer and a water retentive layer. The decorative surface covering may be a vinyl-backed floor covering that can be adhered to a substantially non-aqueous absorptive subfloor with a water-based adhesive. The water retentive layer is formed from a polymer matrix and super absorbent water retentive particles. The water retentive layer may also include a hydrophilic additive to facilitate movement of water from the adhesive to the super absorbent water retentive particles. The water retentive layer may also be applied to the substantially non-aqueous absorptive subfloor.
