This last issue on one coat stucco hit the nail on the head. I have written about one coat stucco before. It is marketed as real stucco, hard coat stucco, etc. but it is far from traditional 3 coat stucco.
One coat stucco base coat comes in a bag marked one coat stucco. The basecoat requires adding sand, or some already has sand. The basecoat normally is applied between 1/4" to 3/8" thick instead of the industry standard thickness for traditional stucco of 3/4 of an inch. Traditional stucco has cement and sand finish coat, where one coat has a synthetic finish. Synthetic finish is an acrylic paint, usually with plastic sand.
