Stucco, which is also known as Portland Cement Plaster, is a substance which is added to the surface of the exterior or interior of buildings. It is a tough, long lasting material which is resistant to rot and fungus, and it is also affordable and doesn’t require a great deal of maintenance. This has made it prized in the construction business and GreenTree Construction uses it extensively in our many renovation projects. It is comprised of water and sand which is combined with other ingredients to produce a type of plaster.
