Giải thích
Three-coat stucco is applied as a scratch coat (scored to bond the next coat), a brown coat (bringing the wall to plane), and a finish coat, totaling about 7/8 inch over metal lath. Reversing the order, doubling the brown coat, or applying one thick coat are not the standard three-coat method.
