What to Expect During a Stucco Application

It starts at the wall, not the finish. The crew installs a weather-resistive barrier and, on a drainable system, a drainage plane, then fastens metal lath to give the stucco something to grip and a weep screed at the base so any water that gets in can drain out. Windows and penetrations are flashed and integrated. This foundation layer is invisible in the finished wall but is the entire reason stucco survives a Michigan winter.

For traditional stucco, a scratch coat is applied and scored, allowed to cure, then a brown coat builds the body and is floated flat — each with cure time in between. For EIFS, a base coat is troweled over the foam with reinforcing mesh embedded in it. Curing cannot be rushed, especially in cold or damp weather; a crew that piles coats on before the previous one is ready is setting up cracking and weak adhesion later.

Once the base is cured, the finish coat goes on in the chosen texture — smooth, sand, dash, or trowel — and color, and control joints are set to manage cracking. Flashing and trim are integrated, surrounding windows and surfaces are cleaned, and the wall is left to fully cure and weather in. A good plasterer protects openings throughout and walks the finished texture with you so you know what to expect as it ages.
