The thickness of stucco on a solid substrate is 5/8 or 1/2 inch. However, on metal base the thickness is 5/8 to 7/8 inch.
Also asked, how thick can you apply stucco?
The correct thickness is then 5/8 inch. Two-coat applications are only for use over solid plaster bases without metal lath. For unit masonry, that thickness is ½ inch.
Likewise, what are the three layers of stucco called? Basically the three coat system consists of paper and wire, a scratch coat, a brown coat and a finish, or “top” coat. This is why it is called a three coat system, lath, scratch and brown.
Simply so, how thick is a stucco coat?
As its name suggests, three coat stucco is applied in three layers: 3/8-inch thick scratch coat, 3/8-inch thick brown coat, and approximate 1/8-inch thick finish coat.
How thick is Scratchcoat?
The finish thickness is between 1/2-in. and 3/4-in. thick. After mortar is evenly spread across the mesh a notched trowel is used to ‘scratch‘ the surface.
