The Scratch Coat is the first layer and got its name because you need a scratch tool to help the other coats adhere.
The Crown Coat is the second layer that involves leveling out the stucco.
The Finish Coat is the visible exterior layer.
Stucco is best applied in cool to warm climates (never freezing or during a heat wave) when it’s cloudy outside so that the material doesn’t dry out. Keeping the stucco moist with water is very important during the installation process because this will also keep it from drying out and cracking.
