For several reasons the fresco will be constructed on a floating wall, built out from an existing brick wall. The construction crew used 3/4" plywood that the students and I covered with water proof roofing paper, which is overlapped in the way that roof shingles are. This was followed by a layer of expanded metal lath that creates a suitable surface to hold the first layer of plaster. Plaster is pressed into the lath in such a way that some of the material pushes through the mesh, creating cement finger that hold the layer onto the wall.
First step, create a suitable surface on the wall to begin applying the plaster onto, no real problems here, just the matter of getting into a rhythm with the small brads, and trying to keep your gloves on and away from the metal lath, that stuff is razor sharp. All in all not so bad, and to see the wall prepared and ready for the scratch coat made all the work worth it. David Marquez and Mike make it look easy.
