Miramar StuccoThis type of wire lath is intended for ceilings and soffits. The design is made to hold the plaster in place, while minimizing the amount of fallouts. It resembles expanded metal lath, in a way but is much more rigid, due to the grooves that run down the length of the wire.The lath is typically about one inch (2.5 cm) wide by four feet (1.22 meters) long by 1⁄4 inch (6.4 mm) thick. Each horizontal course of lath is spaced about 3⁄8 inch (9.5 mm) away from its neighboring courses. In order to fasten the metal lath to the substrate (plywood, masonry, etc.) you will need to either nail or staple the wire to the substrate itself. Typically, staples are used to do this, along with a staple gun and a compressor.
