Abstract
Methods of making a reinforcement mesh, and an architectural molding reinforced by the mesh. The mesh is adhered by an adhesive to the architectural molding. In the mesh, weft yarns bend relative to warp yarns to conform to and against a curved profile of the architectural molding, and the warp yarns are unbent and adhered against the molding.
Claims18
A method of making a reinforcement mesh to adhere and conform to and against a curved profile of curved architectural features on an architectural moulding, comprising:
- combining a pair of fiberglass warp yarns and polymeric weft yarns in the mesh in a hurl leno weave, wherein each individual fiberglass warp yarn in the pair of fiberglass warp yarns have a higher tensile modulus than the polymeric weft yarns;
- extending the pair of fiberglass warp yarns substantially straight in the mesh to extend substantially longitudinally straight against the architectural moulding, and wherein the polymeric weft yarns bend to conform to and against the curved profile;
- and
- applying a pressure sensitive adhesive layer to one side of the mesh for adhering the reinforcement mesh for direct contact of the mesh to the curved profile.
A method of making an architectural moulding, comprising:
- combining a pair of fiberglass warp yarns and polymeric weft yarns in a mesh in a hurl leno weave, wherein each individual fiberglass warp yarn in the pair of fiberglass warp yarns have a higher tensile modulus than the polymeric weft yarns;
- extending the fiberglass warp yarns substantially straight in the mesh to extend substantially longitudinally straight against the architectural moulding, and wherein the polymeric weft yarns bend to conform to and against the curved profile;
- applying a pressure sensitive adhesive layer to one side of the mesh;
- adhering the mesh for direct contact of the mesh to a curved profile of a core of the architectural moulding;
- and
- coating the mesh and the curved profile with a cementitious material.
A method of making a reinforcement mesh to adhere and conform to and against a curved profile of curved architectural features on an architectural moulding, comprising:
- combining a pair of fiberglass warp yarns and polyester weft yarns in the mesh in a huff leno weave, wherein each individual fiberglass warp yarn in the pair of fiberglass warp yarns have a higher tensile modulus than the polyester weft yarns;
- extending the fiberglass warp yarns substantially straight in the mesh to extend substantially longitudinally straight against the architectural moulding, and wherein the polyester weft yarns bend to conform to and against the curved profile;
- and
- applying a pressure sensitive adhesive layer to one side of the mesh for adhering the reinforcement mesh for direct contact of the mesh to the curved profile.
