I need to wrap ext. plywood that's over 4- 4x4s frame with Jumbotex and wire for applying stone veneer. The dims. of the column are 2 x 2 x 4 feet high. I assume I use galvanized staples to attach the Jumbotex moisture barrier...two layers of it overall with the top piece overlapping onto the verticals below... I then wrap the wire around it all? How is the wire attached to the ply/moisture barrier base? There will be a cast-in-place concrete cap over the column. The latter has four 4x4s coming up thru it..each post needing to be flashed in some fashion, right?
