Reinforcement mesh for architectural foam moulding

A longitudinally straight architectural moulding, comprising:

• a core having reversely curved surfaces, outside corners and inside corners, respectively, on a surface thereof;
• a reinforcement mesh to bend and conform to and against the surface of said core;
• bendable polymeric weft yarns in the reinforcement mesh joined with a pair of substantially straight fiberglass warp yarns in a hurl leno weave, wherein each individual warp yarn in the pair have a higher tensile modulus than the polymeric weft yarns, an adhesive on the reinforcement mesh to adhere the reinforcement mesh to directly contact the reversely curved surfaces, outside corners and inside corners, respectively, wherein the bendable polymeric weft yarns are smaller in yield sizes than each individual fiberglass warp yarn in the pair of fiberglass warp yarns, such that the polymeric weft yarns are thinner and weaker, and readily bend relative to the fiberglass warp yarns, wherein the adhesive is a soft ductile adhesive, and the fiberglass warp yarns and the polymeric weft yarns are coated with a ductile, low elastic modulus binder material for the polymeric weft yarns to be bendable relative to the substantially straight fiberglass warp yarns with limited elastic strain and wherein the bendable polymeric weft yarns and the binder material are bendable against the surface of said core, and are bendable relative to the substantially straight fiberglass warp yarns with limited elastic strain to prevent release of the adhesive from direct contact from the curved profile while the substantially straight fiberglass warp yarns extend substantially straight against the longitudinally straight architectural molding;
• and
• a cementitious coating covering the mesh.

A reinforcement mesh to bend and conform to and against a curved profile of curved architectural features on a longitudinally straight architectural moulding, comprising:

• bendable polyester weft yarns in the reinforcement mesh joined with substantially straight fiberglass warp yarns in a hurl leno weave, the fiberglass warp yarns having a higher tensile modulus than the polyester weft yarns, an adhesive on the reinforcement mesh to adhere the reinforcement mesh to directly contact the curved profile having reversely curved surfaces, outside corners and inside corners, respectively, wherein the bendable polyester weft yarns are smaller in yield sizes than the fiberglass warp yarns, such that the polyester weft yarns are thinner and weaker, and readily bend relative to the fiberglass warp yarns, wherein the adhesive is a soft ductile adhesive, and the fiberglass warp yarns and the polyester weft yarns are coated with a ductile, low elastic modulus binder material, for the polyester weft yarns to be bendable relative to the substantially straight warp yarns with limited elastic strain, and wherein the bendable polyester weft yarns and the binder material are bendable to have reversely curved surfaces, outside corners and inside corners, respectively, against the curved profile, and are bendable relative to the substantially straight fiberglass warp yarns with limited elastic strain to prevent release of the adhesive from direct contact from the curved profile while the substantially straight fiberglass warp yarns extend substantially straight against the longitudinally straight architectural molding.
