Abstract
Abstract A curable formulation for application to dry wall surfaces and for jointing and filling dry wall panels. The formulation utilizes an internally plasticized vinyl acetate-ethylene copolymer or alternatively, vinyl acetate-ethylene vinyl chloride interpolymers along with fillers and additives such as suspending agents, defoamers, emulsifiers, and thickeners. The formulation is stable in aqueous suspensions.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
62 words
An ambient curable cohesive self-supporting formulation for application to wall panels and for curing thereon, and consisting of a flowable mixture of an internally plasticized binder selected from the group consisting of vinyl acetate-ethylene copolymers and vinyl acetate-ethylene-vinyl chloride interpolymers together with inert fillers and water, with said binder solids comprising between about 2% and 13% by total weight of the formulation.
Claim 2
Dependent Claim
62 words
An ambient curable cohesive self-supporting formulation for application to wall panels and for curing thereon, and consisting of a flowable mixture of an internally plasticized binder selected from the group consisting of vinyl acetate-ethylene copolymers and vinyl acetate-ethylene-vinyl chloride interpolymers together with inert fillers and water, with said binder solids comprising between about 2% and 13% by total weight of the formulation.
Claim 3
Independent Claim
99 words
The method of treating the surfaces of wall panels which includes the following: (a) preparing a curable formulation consisting of an internally plasticized fluid binder curable upon exposure to the ambient and selected from the group consisting of vinyl acetate-ethylene copolymers and vinyl acetate-ethylene-vinyl chloride interpolymers together with inert fillers and water, with said binder solids comprising between about 2% and 13% by total weight of the formulation; (b) applying said curable formulation to the surface of a wall along and over the edges of adjoining wall panels; and (c) permitting said curable formulation to air-cure in the ambient.
Claim 4
Independent Claim
99 words
The method of treating the surfaces of wall panels which includes the following: (a) preparing a curable formulation consisting of an internally plasticized fluid binder curable upon exposure to the ambient and selected from the group consisting of vinyl acetate-ethylene copolymers and vinyl acetate-ethylene-vinyl chloride interpolymers together with inert fillers and water, with said binder solids comprising between about 2% and 13% by total weight of the formulation; (b) applying said curable formulation to the surface of a wall along and over the edges of adjoining wall panels; and (c) permitting said curable formulation to air-cure in the ambient.
Claim 5
Dependent Claim
20 words
The method as defined in claim 2 being particularly characterized in that said wall panels are gypsum dry wall panels.
Claim 6
Dependent Claim
21 words
The method as defined in claim 2 being particularly characterized in that said wall panels are foamed synthetic resin wall panels.
Claim 7
Dependent Claim
31 words
The method as defined in claim 2 being particularly characterized in that said wall panels are individual panels, and wherein said curable formulation is applied between the mutually adjacent wall panels.
