Claim 1
Independent Claim
69 words
A method of constructing a wall structure comprising: (a) erecting a frame, (b) securing insulation in said frame, (c) covering said insulation with a foam base, (d) positioning a lath over the outer surface of said foam base and (e) coating said foam base with a composition of ethylene vinyl acetate binder, aluminum silicate and glass binder in a relative ratio by weight of 7.5 to 18 to 9.
Claim 2
Independent Claim
69 words
A method of constructing a wall structure comprising: (a) erecting a frame, (b) securing insulation in said frame, (c) covering said insulation with a foam base, (d) positioning a lath over the outer surface of said foam base and (e) coating said foam base with a composition of ethylene vinyl acetate binder, aluminum silicate and glass binder in a relative ratio by weight of 7.5 to 18 to 9.
Claim 3
Dependent Claim
35 words
