When applied over concrete surfaces, the lath does not needed. The applied surface must be clean, dry and free of material like paint or oil. One-coat stucco has just one base coat about 1/2-inch thick with a finish coat, so these claddings are sometimes called “two-coat.”
As a building material, stucco is a durable, attractive, and weather-resistant wall covering. It was traditionally used as both an interior and exterior finish applied in one or two thin layers directly over a solid masonry, brick or stone surface. The finish coat usually contained an integral color and was typically textured for appearance.
