It is difficult to say when exactly they stopped using synthetic stucco, as it varies depending on the region. However, it is generally safe to say that it has been phased out in recent years in favor of newer methods such as HardiePlank. If you are unsure of what material your home is made out of, you can always check with your local municipality or with a contractor.

The use of synthetic stucco has actually been on the decline for a while now. It was once a popular exterior cladding material, but it has since fallen out of favor due to a number of problems that have been associated with it. These include, but are not limited to, poor weather resistance, poor durability, and susceptibility to water damage. As such, it is becoming less and less common nowadays.
