Overview
A variety of cements are used in the stucco mixture, depending on climate and the texture desired. It is usually applied over a base of wire mesh, wooden slot spacers, building paper and plywood or oriented-strand board sheathing (OSB), and is typically applied in three layers by hand toweling or spraying. Some products are applied as a single layer and are more vulnerable to exterior elements, such as wind-driven rain and the sun.
Synthetic Stucco
In addition to traditional stucco exterior surfacing materials, "synthetic stucco" (EIFS) products are being widely promoted and applied to homes in southeastern states. These materials are the subject of a major class action lawsuit because of alleged moisture penetration into wall materials and subsequent mold infestation. In Florida, much of the trim on new housing is synthetic and has created problems with moisture intrusion. The clear coat seals hairline cracks.
Stucco Porosity
The porosity of stucco allows it to absorb water like a sponge. As such, rainwater can migrate from the exterior surface where it may come into contact with wood spacers, and in the worst-case scenario, with plywood or OSB wall sheathing. Water that penetrates stucco must have a way out of the wall. Water should be able to trickle down to the base and come out through weep holes. Alternatively, the space between the stucco and interior surface and wood cracks pose a major risk of water intrusion and mold infestation. Of particular concern are exterior walls on homes and buildings subject to wind-driven rains.
Paint Color Restoration
We have found that 50% of the homeowners we work with want their home painted due to the faded, dull appearance, mostly where the sun is more concentrated. Our exclusive Hydro-Film Technology can restore the original color of a dull, faded surface, eliminating the need for repainting the entire home and saving the homeowner 30-50%, providing the homeowner is satisfied with the original color.
