Abstract
A method for applying pressure sensitive adhesive (PSA) directly to one or both surfaces of carpet underlayment pads in which a liquid PSA polymer composition is first applied as a layer to a release substrate. The polymer layer is dried, forming a dried PSA film on the release substrate. The dried PSA film is then laminated to one or both surfaces of a carpet underlayment pad. Alternately, the film can be encased in a second substrate for storage and future application to a carpet underlayment pad.
