Question 1

How long does stucco take to cure?

Accepted Answer

•

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.

Question 5

What happens to stucco in a fire?

Accepted Answer

•

All of the components of stucco are non-combustible, so the siding material won’t ignite or spread fire to the interior of your home. However, it also expands and contracts with changes in temperature, so it will crack from long exposure to heat. Eventually, fire will spread through those cracks. Still, stucco is one of the best siding materials for fire protection and can keep you and your family safe for an hour, on average.
