There are basically two types of stucco products and two stucco systems:
Traditional vs Acrylic Stucco:
Traditional Stucco:
Consists of cement, silica sand and lime. Traditional stucco comes in bags and is typically 1/5 of cost of the Acrylic stucco. There are virtually unlimited amounts of finish textures that can be produced. Colors for this type of stucco are very tame and light, they are hard to keep consistent when preparing the product and each batch may very slightly. Colors are in a powder form and are mixed with cement with each batch.
