The three dimensional scaffold is pre-formed into three-dimensional shapes that include corners, returns, back-dams, and optional head flaps that provide a scaffold and backing for the application of a fluid applied water/weather-proofing material. The separate fluid applied waterproofing/weatherproofing may be applied by spray, brush or roll and can be asphalt, rubber, plastic or other fluid applied material. The scaffolding may be formed out of mesh, or other semi-porous fiberglass, metal, plastic, synthetic or other material that can be formed into three dimensional shapes. When combined with a fluid applied weather/waterproofing, the scaffolding provides a superior, continuous, reinforced weather/water-proofing system to protect openings and fenestrations in buildings. ## Claims ### Claim 1 A three-dimensional scaffolding for use in flashing a fenestration opening of a structure, comprising: a flange; a return connected to the flange; the flange and return comprising a mesh or semi-porous material with sufficient rigidity to maintain a three-dimensional shape; the scaffolding being non-waterproof prior to installation on a structure; the scaffolding corresponding to a corner piece wherein: the return comprises: a sill/head return, for attaching to a sill/head of the opening, formed of the piece of mesh or semi-porous material, and a jamb return, for attaching to a jamb of the opening, formed of the piece of mesh or semi-porous material; and the flange connects to both the sill/head return and the jamb return. ### Claim 2 (depends on 1) The three-dimensional scaffolding of claim 1, further comprising an adhesive on an interior surface of at least one of the flange and the return, the interior surface corresponding to a surface that attaches to a surface of the fenestration opening or an exterior surface of the structure. ### Claim 3 (depends on 1) The three-dimensional scaffolding of claim 1, wherein: the return defines a first plane, the flange defines a second plane that is orthogonal to the first plane. ### Claim 4 (depends on 1) The three-dimensional scaffolding of claim 1, further comprising a back-dam connected to the return and formed from the mesh or semi-porous material. ### Claim 5 (depends on 4) The three-dimensional scaffolding of claim 4, wherein: the return defines a first plane, the flange defines a second plane that is orthogonal to the first plane, and the back-dam defines a third plane that is parallel and offset from the second plane. ### Claim 6 (depends on 4) The three-dimensional scaffolding of claim 4, further comprising a drip margin between the flange and the return. ### Claim 7 (depends on 1) The three-dimensional scaffolding of claim 1, the return comprising drainage ribs raised from an outer surface of the return. ### Claim 8 (depends on 1) The three-dimensional scaffolding of claim 1, the sill return comprising drainage ribs raised from an outer surface of the sill/head return. ### Claim 9 (depends on 1) The three-dimensional scaffolding of claim 1, wherein: the sill/head return and jamb return define respective first and second planes that are orthogonal to each other, and the flange defines a third plane that is orthogonal to both the first and second planes. ### Claim 10 (depends on 1) The three-dimensional scaffolding of claim 1, further comprising: a sill/head back-dam connected to the sill/head return and formed of the piece of mesh or semi-porous material, and a jamb back-dam connected to the jamb return and formed of the piece of mesh or semi-porous material. ### Claim 11 (depends on 10) The three-dimensional scaffolding of claim 10, the sill/head return comprising drainage ribs raised from an outer surface of the sill/head return. ### Claim 12 (depends on 10) The three-dimensional scaffolding of claim 10, wherein: the sill/head return and jamb return define respective first and second planes that are orthogonal to each other, the flange defines a third plane that is orthogonal to both the first and second planes, and the sill back-dam and the jamb back-dam define a fourth plane that is parallel and offset from the third plane. ### Claim 13 (depends on 10) The three-dimensional scaffolding of claim 10, further comprising a drip margin between the return and the flange. ### Claim 14 (depends on 1) The three-dimensional scaffolding of claim 1, the flange and return being entirely formed from the mesh or semi-porous material. ### Claim 15 A three-dimensional scaffolding for use in flashing a fenestration opening of a structure, comprising: a flange; a return connected to the flange; the flange and return comprising a mesh or semi-porous material with sufficient rigidity to maintain a three-dimensional shape; and, a hinged flap connected to the flange at an edge of the flange opposite from the return; the scaffolding being non-waterproof prior to installation on a structure. ### Claim 16 (depends on 15) The three-dimensional scaffolding of claim 15, the hinged flap having a greater length than the flange. ### Claim 17 A three-dimensional scaffolding for use in flashing a fenestration opening of a structure, comprising: a flange; a return connected to the flange; the flange and return comprising a mesh or semi-porous material with sufficient rigidity to maintain a three-dimensional shape; the scaffolding being non-waterproof prior to installation on a structure; a portion, but not all, the flange and return being formed from the mesh or semi-porous material.
