To repair damaged exterior stucco, you’ll first remove all loose and crumbling material from the damaged area. You then need to thoroughly clean the area and dampen it to ensure proper bonding. After that, you’ll apply a bonding agent to the repair area, then apply new stucco in layers, allowing for curing time between each layer. The final coat should be textured to match the surrounding stucco pattern as closely as possible. Once fully cured, the repaired area can be painted to match the rest of the wall if needed.

It typically takes around 30 to 60 minutes for a window pro to replace one window in standard siding types, but a window in stucco will likely take a bit longer because of the density of materials. Custom architectural windows usually require a longer replacement process because of the additional fitting and securing required.

Solid, unpainted stucco shouldn’t suffer damage from dots of glue used for this task. If the stucco is dirty, you may notice slight marks when you heat and peel the glue away, but these aren’t permanent.

However, not all stucco walls are solid stucco. Some are “faux” stucco with a foam backing. This kind of stucco veneer is more susceptible to damage, including damage from hot glue. We don’t suggest attaching anything to these kinds of stucco walls, so make sure you check the stucco type before starting this project.

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.
