All Lath and lath attachments shall be of corrosion -resistant materials. Attached per ASTM C 1063. R703.7.2 Plaster. Plastering w/ Portland cement plaster shall be not less than three coats when applied over metal lath or wire lath and shall be not less than two coats when applied over masonry, concrete. R703.7.3 Water -Resistive Barriers. Water -resistive barriers shall be installed where cement plaster (stucco) is to be applied over wood -based sheathing, shall include a water -resistive vapor -permeable barrier. The individual layers shall be installed independently such that each layer provides a separate continuous plane and any flashing intended to drain to the water -resistive barrier is directed between the layers. The barriers shall consist of one of the following. 1. Two layers of an approved water resistant barrier material in accordance with R703.2. 2. One layer of an approved water -resistive barrier (paper backed stucco lath) over an approved synthetic house wrap. R703.4 Flashing. Approved corrosion -resistant flashing shall be applied shingle -fashion in a manner to prevent entry of water into the wall cavity or penetration of water to the building structural framing components. Flashing shall be installed at the following locations. • Exterior window/door openings. • Intersection of chimneys or other masonry constructions with frame walls. • Under and at the ends of masonry, wood or metal copings and sills. • Continuously above all projecting wood trim. • Where exterior porches, decks or stairs attach to a wall or floor assembly of wood -frame construction. • At wall and roof intersections • At Built-in gutters.
