New stucco needs proper curing time to ensure its durability. While the curing duration is not exact, several important factors must be considered.

Initial Moist-Curing Period:

New stucco requires at least 48 to 72 hours of moist Curing after application. The surface should be misted with water 2 to 4 times a day to prevent the stucco from drying too quickly.

Drying Time Before Painting:

It is recommended to wait at least 14 days after the final application before painting newly cured stucco. Environmental factors such as humidity levels, ambient temperature, and recent rainfall heavily influence the curing process. Ideally, each layer of stucco needs between 48 and 72 hours to cure properly. However, this short time frame does not mean a complete cure.

Complete Curing: 

The stucco application involves multiple layers, including scratch, brown, and finish coats. Each layer must be adequately cured before adding the next one. Trying to speed up the curing process can lead to issues such as cracks, weak adhesion, and moisture problems.

On average, stucco requires approximately 90 days to complete the curing process and achieve maximum strength. This extended curing period allows moisture to fully evaporate and ensures that each layer bonds correctly.

These guidelines are general: Specific curing durations may need to be adjusted based on local weather conditions and the particular stucco mixture used.
