These are photos of the process we used to frame Casey Roberts piece for
Bluefish.
The frame is 69" x 92 1/4". Made of custom-milled basswood which we stained and finished to match the floor of the lobby, to be its new home.
We used archival Coroplast (gaseous-inert fluted plastic mounting board) in two layers, contact cemented together, with the fluting criss-crossing. Then we mounted ph-neutral natural linen to the face of the mount boards.
Slits were cut into the layers to make room for "S"-hinges made of Lineco linen tape. The piece was mounted using 9 "S"-hinges at the top and 4 more hinges at the bottom to keep the art from the 1/4" OP-2 acrylic.
The package was sealed with points temporarily and then banded by weaving sheet metal straps across the back and screwing them to the frame. Each corner has 2 corner braces screwed in. The back was finished with Lineco acid free paper.
A cleat was ripped and screwed to the top rail of the frame, another on the wall. In addition another block was installed to the bottom rail and one on the wall. Both the top and bottom rails take the (substantial) weight of the piece, while the cleat keeps it vertical.
