The curing time for stucco typically takes several weeks to fully complete. During the curing process, the stucco undergoes a chemical reaction and gradually hardens. It's important to note that curing is different from drying. While the surface of the stucco may dry relatively quickly within a few hours or days, the curing process continues beneath the surface, strengthening and solidifying the stucco. 

It's best to avoid excessive moisture exposure during the curing period, as it can impede the curing process. The exact curing time can vary based on factors such as temperature, humidity, and the specific stucco mixture used.

Stucco is very challenging to DIY, so it’s always best to leave the work to professional stucco contractors. The same recommendation applies to painting a stucco house, which should be left in the reliable hands of a professional exterior painter. Inexperienced DIYers can make several critical mistakes during stucco application, such as:

• Failing to apply sufficiently thick layers for longevity and water resistance

• Uneven application

• Uneven texture across the exterior

• Mixing the stucco improperly, leaving a weak structure

• Failing to texture properly in between coats, leading to cracking and chipping

The average cost of stucco siding is $5,400, ranging from $2,200 to $8,840. Stucco is worth the investment, provided you have the work done by a professional. Not only is stucco an attractive and durable siding material that boosts your home’s curb appeal, but it’s also more energy-efficient than most other siding options, it’s fire-resistant, water-resistant, and more affordable to repair down the road.

Masonry screws are the best option to be used on stucco. They’re thicker and made to penetrate harder surfaces like concrete and cinder blocks. Fluted masonry screws work the best because they create a stronger grasp thanks to the lines on their shafts. If you’re working on exterior stucco, use galvanized screws to prevent corrosion.
