Abstract
New wall to wall carpeting is applied directly over worn broadloom or tile wall to wall carpeting having a backing secured to a hard floor surface (e.g. directly attached, such as by adhesive, to an existing concrete floor) and a top pile surface. The worn carpeting is cleaned and then a high molecular weight acrylic ester polymer emulsion adhesive is sprayed onto the top pile surface of the old carpet. The vinyl backing of one or more new carpet strips is applied directly to the adhesive. A fire retardant is preferably included with the adhesive or separately applied to the top pile surface of the old carpet. If desired the adhesive may be applied to only a small part of the old carpet for holding strips of hook fasteners, and the new carpet backing may include loop fasteners which cooperate with the hook fasteners and hold the new carpet in place.
