Abstract
Abstract A method for installing a sheet of surface covering material on a substrate surface comprising depositing a quantity of a foamed adhesive to the substrate surface, laying the sheet on the adhesive, applying pressure to the sheet so as to spread the adhesive and cause the adhesive to conform to any irregularities of the substrate surface, and allowing the adhesive to dry, thereby bonding the sheet to the substrate surface. Also disclosed is a packaged foamable adhesive for use with this method.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
105 words
A method for installing a sheet of surface covering material on a floor surface comprising: a. depositing a bead of a foamed latex-based adhesive to a portion of said floor surface, b. laying said sheet on said foamed adhesive while said adhesive is wet, c. applying pressure to said sheet for substantially completely collapsing the foam and spreading said adhesive to cover substantially the entire area of contact of said surface covering and said floor surface and thereby causing said adhesive to conform to any irregularities of said floor surface, and allowing said adhesive to dry, thereby uniformally bonding said sheet to said floor surface.
Claim 2
Independent Claim
105 words
A method for installing a sheet of surface covering material on a floor surface comprising: a. depositing a bead of a foamed latex-based adhesive to a portion of said floor surface, b. laying said sheet on said foamed adhesive while said adhesive is wet, c. applying pressure to said sheet for substantially completely collapsing the foam and spreading said adhesive to cover substantially the entire area of contact of said surface covering and said floor surface and thereby causing said adhesive to conform to any irregularities of said floor surface, and allowing said adhesive to dry, thereby uniformally bonding said sheet to said floor surface.
Claim 3
Dependent Claim
23 words
A method as in claim 1 and including: a. depositing said adhesive to the form of a foam from a propellant pressurized receptacle.
Claim 4
Dependent Claim
30 words
A method as in claim 2 and including: a. depositing said adhesive as a bead having a substantial thickness compared to the thickness of the adhesive layer after pressure application.
Claim 5
Dependent Claim
28 words
A method as in claim 3 and including: a. applying pressure to said sheet so as to spread said adhesive and at least partially collapse said adhesive foam.
Claim 6
Dependent Claim
47 words
A method as in claim 1 and including: a. depositing said foamed adhesive as a bead from an aerosol can. b. said aerosol can containing a foamable adhesive composition and a propellant c. said propellant causing said foamable adhesive to foam upon discharge from said aerosol can.
Claim 7
Dependent Claim
22 words
A method as in claim 5 and wherein: a. said foamable adhesive composition comprises a major amount of a vinyl acrylic copolymer.
Claim 8
Dependent Claim
20 words
A method as in claim 6 and wherein: a. said foamable adhesive composition comprises a filled vinyl acrylic copolymer emulsion.
Claim 9
Dependent Claim
29 words
A method as in claim 7 and wherein: a. said foamable adhesive composition is a thixotropic gel having a viscosity upon shaking within the range of about 1500-3500 cps.
Claim 10
Independent Claim
82 words
A method for installing a sheet of surface covering material on a floor surface comprising: a. applying to said floor surface a bead of foamed vinyl acrylic copolymer latex emulsion adhesive composition, b. laying said sheet on said foamed composition while said composition is wet, c. applying pressure to said sheet so as to substantially completely collapse the foam and spread said bead to an even layer, d. drying said adhesive composition, e. thereby adhesively bonding said sheet to said floor surface.
Claim 11
Independent Claim
82 words
A method for installing a sheet of surface covering material on a floor surface comprising: a. applying to said floor surface a bead of foamed vinyl acrylic copolymer latex emulsion adhesive composition, b. laying said sheet on said foamed composition while said composition is wet, c. applying pressure to said sheet so as to substantially completely collapse the foam and spread said bead to an even layer, d. drying said adhesive composition, e. thereby adhesively bonding said sheet to said floor surface.
Claim 12
Dependent Claim
31 words
A method as in claim 9 and wherein: a. said pressure application at least partially collapses said foamed composition causes said composition to conform to any irregularities of said floor surface.
Claim 13
Dependent Claim
58 words
A method as in claim 10 and including: a. providing a propellant charged supply of a foamable vinyl acrylic copolymer emulsion adhesive composition, b. applying said foamed adhesive composition to said substrate surface by discharging said foamable vinyl acrylic copolymer emulsion adhesive composition from said propellant charged supply, c. whereby the propellant foams said foamable composition upon discharge.
Claim 14
Dependent Claim
35 words
A method as in claim 11 and wherein: a. said foamable composition includes a vinyl acrylic copolymer latex emulsion, a clay filler, a plasticizer and a tackifier, and b. said propellant is a halogenated ethane.
Claim 15
Dependent Claim
24 words
A method as in claim 1 and including: a. applying said foamed adhesive at a rate of about 20 oz. per 80 square feet.
Claim 16
Independent Claim
112 words
A method for installing a sheet of floor covering or the like on a floor surface comprising: a. depositing a bead of foamed latex-based adhesive composition from an aerosol type receptacle on said floor surface, b. laying said sheet on said adhesive while said adhesive is wet, c. applying pressure to said sheet while said adhesive is wet so as to substantially completely collapse said foam and spread said bead of adhesive to a uniform layer and cause said adhesive to conform to any irregularities of said floor surface and establish the uniform layer of adhesive, and d. allowing said adhesive to dry, thereby uniformally bonding said sheet to said floor surface.
Claim 17
Independent Claim
112 words
A method for installing a sheet of floor covering or the like on a floor surface comprising: a. depositing a bead of foamed latex-based adhesive composition from an aerosol type receptacle on said floor surface, b. laying said sheet on said adhesive while said adhesive is wet, c. applying pressure to said sheet while said adhesive is wet so as to substantially completely collapse said foam and spread said bead of adhesive to a uniform layer and cause said adhesive to conform to any irregularities of said floor surface and establish the uniform layer of adhesive, and d. allowing said adhesive to dry, thereby uniformally bonding said sheet to said floor surface.
