The undeniable fact about applying stucco and EIFS is that it happens outside. It would be great if the outside gave us perfect weather, 70 degrees Fahrenheit, sunshine and a gentle breeze. If you are a plasterer in temperate climate zones, such as Hawaii, Southern California or Phoenix in the winter, you will find these conditions. The truth is plasters, like mailmen, must carry on through rain, sleet, hail and snow. Winter is upon us and we still need to get the job done.
Understanding how stucco and EIFS dry and/or cure can help one to be successful when plastering in the cold temperatures. One must also recognize the documented guidelines and temperature ranges that are stated in our codes and standards, and those set by product manufacturers (see inset).
