Hard Coat System (most popular):
 

Metro Contracting starts by applying the metal casing around all the edges of where stucco is be applied. Along the bottom weep casing bead will be installed, with small weep holes that moisture can escape through. The 2-ply weather and moisture resistant barrier is applied next. This is an important step, because stucco is breathable material moisture can get through and when it does the 2-ply weather and moisture resistant barrier is there so that the water will run down it and drain through the weep casing at the bottom. Next a strong metal woven wire is installed to add strength to the stucco system. All of the above stages are referred to as the lath, and once the lath has been completed it is time to apply the two layers of stucco material. The first coat or brown coat is a true ½” layer of a stucco cement material, and after it is applied needs 5-10 days to go through its curing process depending on weather and moisture. After the brown coat has cured the acrylic finish coat is applied. The finish coat gives the stucco its texture. Also color can be added to the finish coat, if color is applied to the finish coat there is no requirement for any additional coats such as paint.
