Abstract
Abstract The appearance of simulated textured metal is imparted to a surface, which may comprise part of a design, by mixing a tinted aqueous solution of dextrin with a polyvinyl acetate emulsion to form a liquid base material. This base material is applied to the surface and thereafter a coating comprising a mixture of borax and a metal in powder form is distributed over the uncured base material. As the polyvinyl acetate dries a textured finish which simulates textured metal is obtained.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
109 words
A method for the production of a textured surface on at least a portion of a substrate comprising the steps of: preparing an aqueous solution of dextrin; mixing a polyvinyl acetate emulsion with the dextrin solution to form an acidic liquid base material, the polyvinyl acetate emulsion being characterized by borax incompatibility; preparing an alkaline top powder by mixing borax and a metallic powder; coating at least a portion of a substrate with the liquid base material; dusting the liquid base material coating with the top powder; removing any excess top powder from the base material prior to complete curing thereof; and permitting the coated base material to harden.
Claim 2
Independent Claim
109 words
A method for the production of a textured surface on at least a portion of a substrate comprising the steps of: preparing an aqueous solution of dextrin; mixing a polyvinyl acetate emulsion with the dextrin solution to form an acidic liquid base material, the polyvinyl acetate emulsion being characterized by borax incompatibility; preparing an alkaline top powder by mixing borax and a metallic powder; coating at least a portion of a substrate with the liquid base material; dusting the liquid base material coating with the top powder; removing any excess top powder from the base material prior to complete curing thereof; and permitting the coated base material to harden.
Claim 3
Dependent Claim
12 words
The method of claim 1 further comprising: tinting the liquid base material.
Claim 4
Dependent Claim
26 words
The method of claim 2 wherein the step of tinting comprises: forming a suitably colored aqueous dextrin solution prior to mixing with the polyvinyl acetate emulsion.
Claim 5
Dependent Claim
44 words
The method of claim 1 wherein the step of preparing the aqueous dextrin solution comprises: mixing a coloring material with water; and adding a powdered dextrin having at least 95% solubles to the colored water solution to form a tinted aqueous solution of dextrin.
Claim 6
Dependent Claim
38 words
The method of claim 4 further comprising: selecting a polyvinyl acetate emulsion for mixing with the aqueous dextrin solution, the polyvinyl acetate emulsion being characterized by minimum borax stability and employment of polyvinyl alcohol as an emulsifying agent.
Claim 7
Dependent Claim
19 words
The method of claim 5 further comprising the step of: adding a buffering agent to the liquid base material.
Claim 8
Dependent Claim
18 words
The method of claim 5 further comprising the step of: adding a preservative to the liquid base material.
Claim 9
Dependent Claim
18 words
The method of claim 5 further comprising the step of: adding a plasticizer to the liquid base material.
Claim 10
Dependent Claim
35 words
The method of claim 6 wherein the step of adding a buffering agent comprises: adding an aqueous solution of sodium acetate powder and vinegar to the aqueous solution of dextrin and a polyvinyl acetate emulsion.
Claim 11
Dependent Claim
29 words
The method of claim 7 wherein the step of adding a preservative comprises: adding a metallic soap solution to the aqueous solution of dextrin and a polyvinyl acetate emulsion.
Claim 12
Dependent Claim
27 words
The method of claim 9 wherein the step of adding a plasticizer comprises: adding hexylene glycol to the aqueous solution of dextrin and a polyvinyl acetate emulsion.
Claim 13
Dependent Claim
26 words
The method of claim 10 wherein the dextrin is a yellow pyrodextrin and said method further comprises: adding a buffering agent to the liquid base material.
Claim 14
Dependent Claim
18 words
The method of claim 12 further comprising the step of: adding a plasticizer to the liquid base material.
Claim 15
Dependent Claim
26 words
The method of claim 5 further comprising the step of: embedding decorative objects in the liquid base material coating prior to dusting with the top powder.
Claim 16
Dependent Claim
57 words
The method of claim 5 wherein the substrate has a release surface and wherein said method further comprises: removing the coated base material from the substrate subsequent to removal of excess top powder therefrom and prior to curing thereof and applying the thus removed and partially cured elements consisting of coated base material to a second substrate.
