Accordingly, what is the first coat of stucco called?

Secondly, what is a 3 coat stucco system? Cement-based three coat stucco systems have been providing a long-lasting, attractive cladding for buildings for over 100 years. 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.
Additionally, what is a 2 coat stucco system?
Two-Coat Stuccoing In a two-coat application, the brown coat is eliminated and the finish coat is applied directly to the scratch coat. As shown in the illustration, the scratch coat of QUIKRETE® Base Coat Stucco is applied to a 3/8" thickness, grooved, and cured as in a three-coat system.
Should stucco be sealed?
Stucco can and should be sealed properly to prevent moisture intrusion. If new, stucco can be sealed with a clear concrete/ masonry sealer, which will penetrate into the stucco and stop moisture entrance. These are typically silicone type sealers.
