Stucco-Based Surfacing System And Method

Abstract

A building surfacing system is described, the system including a stucco substrate affixed to and disposed upon a support panel, a primer coating applied to a surface of the stucco substrate so as to form a primed stucco substrate, a first sealant coating applied to the primed stucco substrate, an intermediate mesh layer disposed upon the first sealant coating, and a second sealant coating applied to the intermediate mesh layer while the intermediate mesh layer is disposed upon the first sealant coating. A related method for providing a water-proof exterior surface to a building structure is further described.

1 . A building surfacing system, the system comprising:
 a stucco substrate affixed to and disposed upon a support panel,   a primer coating applied to a surface of the stucco substrate so as to form a primed stucco substrate,   a first sealant coating applied to the primed stucco substrate,   an intermediate mesh layer disposed upon the first sealant coating, and   a second sealant coating applied to the intermediate mesh layer while the intermediate mesh layer is disposed upon the first sealant coating.   
     
     
         2 . The surfacing system according to  claim 1 , wherein the first and second sealant coatings each comprise a ceramic-fortified acrylic polymer emulsion. 
     
     
         3 . The surfacing system according to  claim 2 , further comprising at least one decorative coating applied to the second sealant coating. 
     
     
         4 . The surfacing system according to  claim 1 , wherein the stucco substrate further comprising a metal lath disposed between the support panel and the stucco substrate. 
     
     
         5 . The surfacing system according to  claim 4 , further comprising at least one decorative coating applied to the second sealant coating. 
     
     
         6 . The surfacing system according to  claim 4 , wherein the intermediate mesh layer is comprised of a woven fabric. 
     
     
         7 . The surfacing system according to  claim 4 , wherein the first and second sealant coatings each comprise a ceramic-fortified acrylic polymer emulsion. 
     
     
         8 . A method of providing an exterior surface to a building structure, the method comprising
 applying a stucco substrate to a support panel, which support panel is affixed, or configured to be affixed, to the building structure,   applying a primer coating to a surface of the stucco substrate so as to form a primed stucco substrate,   applying a first sealant coating to the primed stucco substrate,   disposing an intermediate mesh layer upon the applied first sealant coating, and   applying a second sealant coating to the intermediate mesh layer disposed upon the applied first sealant coating,   
       so as to form the exterior surface of the building structure. 
     
     
         9 . The method according to  claim 8 , wherein the first and second sealant coatings each comprise a ceramic-fortified acrylic polymer emulsion. 
     
     
         10 . The method according to  claim 9 , further comprising applying at least one decorative coating to the second sealant coating. 
     
     
         11 . The method according to  claim 8 , further comprising attaching a metal lath to the support panel and applying the stucco substrate to the metal lath when applying the stucco substrate to the support panel. 
     
     
         12 . The method according to  claim 11 , further comprising at least one decorative coating applied to the second sealant coating. 
     
     
         13 . The method according to  claim 11 , where the intermediate mesh layer comprised of a woven fabric. 
     
     
         14 . The method according to  claim 11 , wherein the first and second sealant coatings each comprise a ceramic-fortified acrylic polymer emulsion.
