  • the exterior surface so so formed is substantially water-proof.
  • water proof it is meant that the surface would resist w r ater leakage sufficiently to meet minimum industry standards for designation as a "water proof exterior surfacing in construction of buildings or other structures.
  • one such standard is set forth in PSi Environmental Geotechnicai Construction, Consulting-Engineering-Testing, Project No. 823-66078, Laboratory No. SPT-6G1Q4, Report Date September 4, 1996, and would be considered an industry standard for designation as "water-proof” which could be met by preferred surfacing systems and preferred methods of this invention.

  • the support panels when in sheet or panel form are typically cut into manually manageable pieces and are attached by nails, screws or other fasteners to framing studs, roof trusses or the like, that form the structure's frame.
  • the support panel is also covered with a vapor barrier, preferably fastened to the support panel material in a conventional manner.
  • Suitable vapor barriers can include, for example, liquid applied barriers, and solid material barriers which are mechanically fastened to the support panel.
  • Commercially available examples of such barriers are asphalt-based emulsions, water- based polymer-modified liquid moisture barriers, grade D asphalt paper, as well as TYVEK brand vapor barrier material.
  • Some examples of liquid applied barriers are GOLD COAT, EMERALD COAT and VAPOR SEAL brand coatings from Sto Corp. of Atlanta, Georgia, USA.
  • a lath typically made of metal, metal alloy or other rigid material will be nailed or otherwise attached to the installed support panel and vapor barrier.
  • the lath can be attached to the panels prior to their attachment to the framed studs, when using the kind of support panels that are cut into boards, e.g., plywood, and attached to the studs.

  • an intermediate woven fiber or cloth layer preferably is disposed upon the first sealant coating, typically by troweling it into the wet first sealant coating.
  • the intermediate woven cloth layer is typically comprised of natural or synthetic fibrous materials and can be obtained commercially from, for example, SealMark Manufacturing Corporation, which sells such suitable woven cloth materials for use in roofing applications.
  • the intermediate mesh layer is pressed into the first sealant coating in order to allow sealant coating material to adhere to the mesh layer and vice versa.
  • a second sealant coating (preferably comprised of the same material as that which forms the first sealant coating) is then applied to the intermediate mesh layer while the intermediate mesh layer is disposed on the first sealant coating, thereby suspending the mesh layer within a thick combination of sealant comprised of the first and second coatings.

  • a metal lath 2 is installed by nails or screws to the vapor barrier-covered panel A.

  • a first sealant coating 4 of the ceramic-based acrylic polymer above- described an intermediate woven mesh layer 5, and a second coating 6 of the sealant.
  • the sealed, primed stucco substrate may be decorated in a variety of ways beyond simply decorative painting or texturizing. For example, decorative bands and crown moldings, as well as decorative stenciling, may be applied to the stucco.

  • the intermediate woven layer in the sealant coating provides added strength and resistance to cracking due to movement of the support panel and frame structure over time.
