Abstract
Abstract An article of construction comprising a substrate coated with a multi-ply coating including an acrylic resin coating adhered to the surface of said substrate and underlying and adhered to an overlying acrylic resin coating, the acrylic resin of said underlying coating being a different acrylic resin than that of said underlying coating, the adhesive bond between said overlying and underlying coatings being stronger than if the bond were between two coatings formed from the same acrylic resin, and including embodiments in which fly ash is included in either the underlying or the overlying coating.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
131 words
An article of construction comprising a substrate coated with a multi-ply coating, one of said coatings being an underlying coating adhered to the surface of said substrate and underlying and adhered to an overlying coating, said underlying coating being weather-resistant and fire-resistant and being formed from an aqueous adhesive composition which includes an elastomeric roof acrylic resin, said overlying coating being formed from an aqueous adhesive composition which includes an acrylic resin which is different from the acrylic resin of said underlying coating, the adhesive bond between said overlying and underlying coatings being stronger than if the bond were between two coatings formed from the acrylic resin of said underlying coating, and wherein said overlying coating has adhered thereto a top coating which consists essentially of an elastomeric roof acrylic resin.
Claim 2
Dependent Claim
131 words
An article of construction comprising a substrate coated with a multi-ply coating, one of said coatings being an underlying coating adhered to the surface of said substrate and underlying and adhered to an overlying coating, said underlying coating being weather-resistant and fire-resistant and being formed from an aqueous adhesive composition which includes an elastomeric roof acrylic resin, said overlying coating being formed from an aqueous adhesive composition which includes an acrylic resin which is different from the acrylic resin of said underlying coating, the adhesive bond between said overlying and underlying coatings being stronger than if the bond were between two coatings formed from the acrylic resin of said underlying coating, and wherein said overlying coating has adhered thereto a top coating which consists essentially of an elastomeric roof acrylic resin.
Claim 3
Dependent Claim
26 words
An article according to claim 1 wherein said substrate is a roofing substrate and wherein said overlying coating consists essentially of an elastomeric roof acrylic resin.
Claim 4
Dependent Claim
19 words
An article according to claim 1 wherein the acrylic resin of said overlying coating is an indoor acrylic resin.
Claim 5
Dependent Claim
23 words
An article according to claim 2 wherein said top coating includes a sufficient amount of white pigment to impart thereto a white color.
Claim 6
Dependent Claim
39 words
An article according to claim 1 wherein said underlying coating has a thickness of about 25 to about 75 mils, and wherein each of said overlying and top coatings has a thickness of about 5 to about 20 mils.
Claim 7
Dependent Claim
22 words
An article according to claim 1, 2, 3, or 4 wherein said overlying coating consists essentially of acrylic resin and fly ash.
