Abstract
Abstract A carpet and pad installation avoids the need for stretching and tackless strips by utilizing a pad with pressure-sensitive adhesive on its upper and lower surfaces. The pad is first laid on the floor surface and trimmed as required, with its lower adhesive surface adhering to the floor. Its upper surface has a removable release film covering the pressure-sensitive adhesive, permitting the carpet to be unrolled over the release film and then cut and seamed as required. The seamed carpet is folded back and the release film is removed from the exposed area of the carpet cushion, then the carpet is pressed down onto the exposed area of adhesive. Then another portion of the carpet is folded back, the release film is removed from that area, and that portion of the carpet is pressed onto the exposed pressure-sensitive adhesive of the carpet cushion.
