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.

1. A carpet pad for installation between a floor and a carpet, for retaining the carpet and pad in place by adhesion without need for stretching, comprising: a pad with upper and lower surfaces and of such thickness, density and compressibility as to enable it to serve as a carpet padding; a scrim webbing on at least the lower surface of the pad for maintaining dimensional stability of the pad, with means for retaining the scrim webbing to the pad; a sealant applied to both surfaces of the pad; and pressure-sensitive adhesive on both surfaces of the pad for adhering to a floor and to the underside of a carpet to hold the carpet and pad in position while allowing for temporary lifting of the carpet wholly or in localized areas when desired. 2. The carpet pad of claim 1, further including a removable release film on one side of the pad, to facilitate roll storage and for manipulating a carpet on the laid pad, before adhering the carpet to the pad. 3. The carpet pad of claim 1, with the scrim webbing on both surfaces of the foam pad. 4. The carpet pad of claim 1, wherein the pressure-sensitive adhesive is in spaced strips on the surfaces of the pad. 5. The carpet pad of claim 4, wherein the spacing between the strips of adhesive is not more than two inches. 6. The carpet pad of claim 1, wherein the pad is urethane foam. 7. A method of manufacturing an adhesive carpet pad for installation between a floor surface and a carpet for retaining the carpet and pad in place by adhesion without stretching, comprising: applying and retaining to a foam pad of such thickness, density and compressibility as to enable it to serve as a carpet padding, a scrim webbing on both surfaces of the foam pad, for maintaining dimensional stability of the foam pad; applying a sealant to both surfaces of the foam pad; applying a non-permanent pressure-sensitive adhesive to both surfaces of the foam pad; and adhering a release film to the adhesive on one side of the pad so the carpet pad can be stored in a roll. 8. A method of installing a carpet with a carpet cushion, comprising: positioning a carpet cushion on a floor surface and trimming as required, said carpet cushion having a pressure-sensitive adhesive on its upper and lower surfaces and a removable release film on the pressure-sensitive adhesive on the upper surface, and the carpet cushion including means for maintaining dimensional stability in the carpet cushion; positioning the carpet on top of the release film on the carpet cushion and cutting and seaming the carpet as required; folding back the carpet and removing the release film from the exposed area of the carpet cushion; pressing the carpet down onto the exposed pressure-sensitive adhesive on the upper surface of the carpet cushion; folding back another portion of the carpet and removing the release film from that area and then pressing that portion of the carpet onto the exposed pressure-sensitive adhesive of the carpet cushion; and performing final trimming at the carpet edges as required when the entire carpet has contacted the adhesive. 9. The invention defined in claim 8, including installing rigid spacer strips on the floor along the walls of the room prior to laying the carpet cushion. 10. The invention defined in claim 9, wherein the rigid spacer strips have pressure-sensitive adhesive on their upper and lower surfaces. 11. The invention defined in claim 8, wherein the pressure-sensitive adhesive is in spaced strips on the surfaces of the carpet cushion. 12. The invention defined in claim 11, further including stapling the carpet cushion to the floor as needed prior to positioning the carpet on the release film of the carpet cushion, the stapling being done between the spaced strips of adhesive on the upper surface of the carpet cushion so that dimples formed in the carpet cushion at the stapling will occur in areas devoid of adhesive, whereby the carpet will span the dimples without adhering into them. 13. The invention defined in claim 11, wherein the spaced strips are in a serpentine configuration. 14. The invention defined in claim 8, wherein the means for maintaining dimensional stability comprises a scrim webbing retained on at least the lower surface of the carpet cushion. 15. The invention defined in claim 8, wherein the means for maintaining dimensional stability comprises a heat formed skin of increased density at the upper and lower surface of the carpet cushion, the cushion comprising a high density urethane foam. 16. A carpet and pad installation, retained in place on a floor surface by adhesion, without need for stretching, comprising: a carpet cushion in contact with the floor surface, the cushion being of such thickness, density and compressibility as to enable it to serve as a carpet cushion, with pressure-sensitive adhesive on the lower surface of the carpet cushion bonding it to the floor surface, and with pressure-sensitive adhesive on the upper surface of the carpet cushion; means for maintaining dimensional stability in the carpet cushion; and a carpet laid on the upper surface of the carpet cushion and bonded thereto by the pressure-sensitive adhesive, said adhesive being non-permanent and allowing for temporary lifting of the carpet wholly or in localized areas when desired. 17. The invention defined in claim 16, wherein the carpet has a primary backing as its only backing. 18. A carpet pad for installation between a floor and a carpet, for retaining the carpet and pad in place by adhesion without need for stretching, comprising: a high-density urethane foam pad, of such thickness, density and compressibility as to enable it to be used as a carpet padding, and with upper and lower surfaces; a heat-formed crust or skin of increased density on the surfaces of the foam pad for maintaining dimensional stability of the foam pad, and for sealing the porosity of the foam pad at the surfaces; and pressure-sensitive adhesive on both surfaces of the foam pad for adhering to a floor and to the underside of a carpet to hold the carpet and pad in position while allowing for temporary lifting of the carpet wholly or in localized areas when desired. 19. The carpet pad of claim 18, further including a removable release film on one side of the pad, to facilitate roll storage and for manipulating a carpet on the laid pad, before adhering the carpet to the pad. 20. The carpet pad of claim 18, wherein the pressure-sensitive adhesive is in spaced strips on the surfaces of the pad. 21. The carpet pad of claim 18, wherein the surfaces of the foam pad are waffled, the adhesive being rolled on, so that less adhesive is required.
