I have been asked exactly what is stucco? Well it is a mortar mix that you use for siding. Mixed with sand and lime with some water and a few other ingredients, mostly cement.
Stucco has become popular lately, it give a nice architectural look to your home. Back in the day, many Italians used this for their homes in Europe. Stucco can also me molded into shapes that are used on the home as well.
Its a nice addition to your home, but must be done by a professional, this is not for the DIY person.
