What is stucco?
Stucco is a decorative coating for walls and ceilings and for decoration, usually composed of cement, sand, and lime, and applied while wet. It’s a popular choice for exterior surfaces.
Can you use stucco over drywall?
No, traditional stucco is not suitable for direct application to drywall because of its weight and moisture content. Drywall cannot withstand the moisture present in stucco and it’s not strong enough to support its weight. However, there are stucco-like products designed for interior use that can be applied over drywall.
What are the advantages of drywall?
Drywall is quick and easy to install, it has a smooth finish that is perfect for painting, is relatively inexpensive, and offers some fire resistance due to the water content in the gypsum.
