Stucco is porous and it needs to breathe. Painting the surface of fresh stucco will trap moisture between the waterproof membrane that separates the stucco from the walls of your home. The paint could bubble, peel, and chip as the moisture attempts to escape.

Stucco walls are insulated with foam padding. When you use a layer of foam board underneath a stucco wall, also known as the one coat system, you are providing a solid backing for the stucco and adding extra insulation to the wall at the same time.

Stucco application typically requires three coats. The initial “scratch coat” provides adhesion to the building. The “brown coat”, which comes second, is responsible for creating an even surface. Finally, the “finish coat” determines the stucco's outward appearance.
