Carpet floor covering and method
Abstract
Abstract A MANUALLY RELEASABLE ASSEMBLY OF ADHESIVELY-SECURED CUSHION-BACKED CARPETING IS DISCLOSED. THE SUBSTRATE FLOORING IF IN A POROUS OR ROUGH CONDITION IS COATED WITH A NONPOROUS FILM FORMER SUCH AS A SEALER TO FORM A SMOOTH SURFACE. AFTER THE SEALER HAS DRIED, A CONTROLLED THICKNESS LAYER OF HIGH-TEAR STRENGTH FILM-FORMING ADHESIVE, SUCH AS ONE COMPRISING NATURAL LATEX, IS APPLIED TO THE FLOOR. BE- FORE THE ADHESIVE FILM HAS DRIED, A SECTION OF LOW-TEAR STRENGTH CUSHION-BACKED CARPETING IS APPLIED TO THE ADHESIVE FILM. THE FILM AND ATTACHED CARPETING CAN BE PARTED FROM THE SMOOTH FLOORING SURFACE SOLELY BY MANUAL FORCES WITHOUT TEARING THE CUSHION OR LEAVING ANY OF THE CUSHION OR THE ADHESIVE FILM ON THE FLOOR.
