• Rigid Backwall, Wallboard, Plywood, Paneling, and Wall Sheathing.
Use a weather barrier to cover the sheathing, overlapping the joints, shingle fashion. Following local building codes, install lath. Galvanized nails or staples should be placed 6” on center vertically and 16” on center horizontally and driven into the studs at least 1”.

• Concrete, Masonry, Stucco, or Block That Is Clean and Untreated.
Check new concrete surfaces for form oil or release agent. If either is present, use muriatic acid to clean the surface then rinse completely and score the surface with a wire brush.

• Concrete, Cementitious Stucco, and Brick That Is Dirty, Sealed or Painted.
Return surface to original condition by sandblasting or waterblasting (clean area to remove sandblast dust) or attach lath with concrete nails. Use a bonding agent on the wall and in the mortar mix.
