Abstract

A carpet pad has pressure sensitive adhesive preapplied on one or both surfaces, for retaining the pad and a carpet in place on a floor by adhesion without the need for stretching. The pad or cushion in one embodiment has a film or sealant on the surfaces of the pad, with pressure sensitive adhesive on at least one of the sealed surfaces for adhering to floor surface or the underside of a carpet. In another embodiment, the pressure sensitive adhesive is a hot melt adhesive, not water-based. The hot melt pressure sensitive adhesive is applied to an uncoated porous padding surface which would be unsuitable for a water-based pressure sensitive adhesive due to excessive wicking-in of such an adhesive. An optional scrim webbing may be applied over the pressure sensitive adhesive, in either embodiment. The scrim webbing adds dimensional stability and also enables the carpet pad to be moved around on a floor or against another surface without sticking, prior to the application of pressure.
