Stucco is an exterior cement plaster wall covering. It is usually a mix of sand, Portland cement, lime and water, but may also consist of a proprietary mix of additives including fibers and synthetic acrylics that add strength and flexibility. Modern synthetic stucco can be applied as one coat system or a three-coat stucco system.
Exterior Insulation and Finishing System (EIFS) is a type of building exterior wall cladding system that provides exterior walls with an insulated finished surface and waterproofing in an integrated composite material system. Both Stucco and EIFS systems are finished with an acrylic finish coat mixed with some type of aggregate to give it texture. You will find both of these systems in both the commercial and residential markets.
