During "stucco installation," several common mistakes should be avoided to ensure a successful and long-lasting finish. One frequent error is inadequate surface preparation, which can lead to poor adhesion and cracks. Not using a proper moisture barrier is another critical mistake that can result in water damage over time. Additionally, applying stucco in unsuitable weather conditions—such as extreme heat or cold—can negatively impact curing. It's also essential to avoid inconsistent mixing of materials, as this can lead to variations in texture and strength. Lastly, failing to allow the stucco to cure properly can result in surface issues, so following recommended drying times is crucial.
