Traditional hard coat stucco can be used to cover walls in a home or commercial building as it is a highly durable material. The cement and plaster composition of hard coat stucco makes it very fire resistant; moreover, it can last up to fifty years before needing to be replaced.
Main Advantages Of Hard Coat Stucco
There are many advantages to hard coat stucco. Unlike traditional stucco, hard coat stucco is easy to maintain. If you are considering hard coat stucco for your home or business, it may also be one of the most cost-efficient options.
This type of stucco performs well in humid and hot climates as it will not expand or shrink. Compared to EIFS stucco, traditional hard coat stucco is better for insulation. The other advantage of hard coat is that it allows for virtually limitless customization and adapts to many different types of tints and colors.
As far as maintenance, owners must remember to perform relatively regular pressure washing and pay attention to small cracks or hairline lines that could allow moisture in and compromise the integrity of the hard coat stucco. A properly installed system is worth the time and effort it takes to ensure the quality of the finished product.
Some Disadvantages…
Although hard coat stucco is more durable than soft coat stucco, it is more susceptible to water damage. It can also be prone to cracks, dings, and efflorescence. In fact, these issues are the most common complaints regarding this type of stucco.
Installation Of Hard Coat Stucco
Traditional and modern hard coat stucco is usually applied in three coats. The first coat of stucco is a water-resistant barrier that is placed behind the exterior wall covering. It serves as a waterproofing barrier to prevent liquid water from penetrating the wall assembly. Next, a metal lath is installed, which contains accessories such as a weep screed and plaster stop. Nails are then placed through the metal lath. Lastly, the coat of hard coat stucco is applied.
Hard coat stucco can be applied by hand or with the assistance of a machine. Premium hard coat stucco is often made with portland cement/lime, which is a natural cement-based compound. A small amount of fine sand is added to the mix to increase the bonding strength. The application process usually takes two to three coats to fully adhere the hard coat stucco to the wall. The walls are then covered with vapor-permeable building paper.
Hard Coat Stucco Homes
Stucco is a common material used to cover homes since it is resistant to freeze-and-thaw cycles and hurricane-strength winds. It is also highly resistant to mold and termites.
A hard coat stucco is a nice option for exterior walls but can be risky if it’s not installed correctly. The cladding can be more sensitive to moisture that seeps in through cracks and therefore more vulnerable to failure. As such, hard coat stucco is recommended for houses that have large overhangs and are located in dryer climates.
In addition to its benefits, this material is cheaper than real stucco, which is a great choice for exterior walls in a house. The materials are cheap, and the labor required for installation is very low, making it a good choice for a homeowner’s budget.
A traditional hard coat stucco provides a classic exterior finish to a home, one resembling that of brick. If you are having issues with existing hard stucco coats that need repair, it is best to consult an expert before doing so. Generally, repairs are simple for those who know what they are doing but they still require expertise and experience. Always go for an experienced and reputable contractor who can provide a high quality of work.
