How to Prevent Stucco Cracks

When Should You Repair Stucco Cracks? (The Truth) - Waypoint Property  Inspection

Although stucco is a long-lasting material, it is porous and rigid, making it prone to cracking. When cement expands and contracts, it can generate cracks. Some cracks are just cosmetic, such as hairline cracks (less than 1/8 inch/3 mm deep), but others can pose structural problems (over than 1 inch/25 mm deep). Preventative maintenance is always the best approach to tackle problems before they arise, and the exterior of your home is no exception.

Cracking is contributed by poor workmanship, improper lath type and installation, insufficient curing, inconsistent thickness of stucco application and poorly mixed stucco. Even if the stucco is placed correctly and all of the conditions are ideal, it will still most likely crack.

Water will be able to reach the drainage plane through cracks, resulting in an unpleasant exterior and dissatisfied homeowners. On large slabs, however, fractures can be expected near windows and doors, as well as at any transition point, such as a corner. Create stress-relieving places to control fractures.

Take the following procedures to keep your stucco from cracking and preserving the value of your home:

Install control joints. These joints are deliberately placed holes in regions where the stucco is likely to crack. They work in the same way as gaps in sidewalks do when cement expands and contracts, properly positioned spaces help prevent major stucco breaking. By allowing the stucco to shift, control joints ease the stress that occurs over time.

Purchase a weep screed. Moisture problems are a common cause of stucco cracks. Weep screeds are venting that support keep your stucco thick, preventing cracks and other flaws. It’s a component that prevents cracks by allowing water to escape, reducing the load on the stucco. The base of the concrete is covered with a weep screed, which allows moisture to escape and prevents cracking caused by trapped water.

Apply a weather-resistant barrierThis coating will assist your stucco withstand harsh weather conditions if you apply it underneath it. It aids in the cement’s ability to withstand excessive moisture brought on by bad weather. Depending on your location’s environment, this coating could be one or two layers thick. Changes in the moisture and temperature of the building material are the most typical causes of cracks – a strong protective coating will provide a barrier between the exterior of your home and the environment, allowing it to withstand harsh weather.

Use corner beads. Large concrete slabs are prone to shifting because they are hard and inflexible. You should expect cracks where the stucco meets the corners of your home’s exterior, so add corner beads to lessen the effects. They use a flexible plastic strip attached to the corners to isolate the stucco from the other components, which will help prevent cracks.

Hire a professional. Hire an experienced repairman or painter to mend the stucco on the outside of your house. This procedure includes mending exterior cracks; an expert will ensure that your stucco remains stable for many years.
