The Basics of Waterproofing Stucco
Waterproofing Stucco Tampa isn’t as complicated as some homeowners or DIYers think. It s more than just slapping a coat of waterproofing on the outside. Proper waterproofing of stucco requires an in-depth understanding of how to protect the stucco surface. The water-repellent component of the stucco coating has to be applied appropriately and adequately permitted to dry before another stucco coat or finish can be used. Correctly applying, qualifying, and drying the waterproofing component of the stucco will ensure years of trouble-free water resistance for your home and surrounding area.
For example, one significant difficulty with waterproofing stucco walls is the tendency for water to penetrate the surface underneath the stucco coat. This can result in wall rot, cracking, shrinking, potholes, and other damage that will compromise the structural integrity of your home. Another problem often found with unpermitted wetness in the wall cavities of stucco walls is wall flaking. This can cause damp areas around the outside of the home to become very itchy and uncomfortable.
Waterproofing stucco begins with the preparation of the surface to be waterproofed. The most commonly used waterproofing agent is Portland cement. The most effective way to apply Portland cement is with a high-pressure stream. However, because of its portability and ease of application, regular amounts of Portland cement are also available in various Home Depot, Lowe’s and other large home supply stores.
The exterior surface of the home is then prepared by sanding and cleaning it to remove all previous coats of sealant. The goal of this preparation is to make it as smooth as possible so that the new waterproofing stucco exterior layer will adhere properly to the surface. Once the surface is smooth and even, a penetrating silicon waterproofing agent is then applied. This penetrates the surface quickly and deeply, making it difficult for water to penetrate. As the penetrating agent works to form a layer of protection on the surface of the home, the interior layer of unadulterated Portland cement is applied.
Although this process of waterproofing stucco patches is an effective way to repair many cracks and small holes in Portland cemented walls, it must be combined with preventative maintenance. Unlike asphalt shingles, the adhesive used to seal the stucco patch will not wear away with time, allowing water to percolate through the patch into the interior cavities of the house. However, the waterproofing agent used to repair these areas must be reapplied after every twenty to thirty years. Applying the water-repellant agent to the walls once each application guarantees its effectiveness.
To ensure that the stucco waterproofing process is as effective as possible, homeowners should also periodically assess their exterior walls for deterioration. Mildew, tree sap, and algae growth can all be issues that compromise the effectiveness of the waterproofing agents. These organic elements will decrease the bond between the exterior wall and the stucco patch over time. If this problem is ignored, the patch will not seal sufficiently to prevent water from leaking into the house. If this problem is left unchecked, it could also begin to rot, eventually weakening the structure of the home. Regular cleaning and maintenance can help prevent the problems from occurring.
It is important to understand that the proper preparation of the surface of the home in order to waterproof stucco involves more than just applying a protective coating. Proper care and maintenance of the surface will help keep it looking its best for longer. Over time, any surface that becomes weathered will lose its bond with the stucco patch. With this condition, the new waterproofing stucco coat could become weaker and not hold as tightly. Eventually, the repair job will be completely unnecessary. Instead, it will have to be replaced, costing homeowners more money than anticipated.
If homeowners are worried about leaks or water damage that may occur around their homes, they should contact a professional waterproofing company immediately. Waterproofing companies can perform a variety of services, ranging from repairing small cracks to more substantial, time-consuming projects. Some companies may even offer services to repair damaged structures that were previously damaged by storms or heavy rains. By sealing surfaces and using a waterproof finish, many problems can be avoided.
