The re-stucco process can be overwhelming and stressful. Discover the causes of stucco cracks, the importance of proper curing, and why avoiding shortcuts like painting can save you time and money.
1. Why Does Stucco Crack? Top Reasons and Solutions
Stucco cracks are a common concern for homeowners and business owners. These cracks not only affect the aesthetics of your property but can also indicate deeper issues. Here are the main causes of stucco cracking:
Improper Curing of the Base Coat: When the base coat isn’t cured correctly, it fails to develop the strength needed to resist cracking over time.
Structural Movement: Shifting or settling foundations create stress on stucco, leading to cracks.
Low-Quality Materials or Poor Workmanship: Using subpar materials or hiring unskilled labor can compromise the integrity of your stucco.
Pro Tip: Addressing these factors during the installation process can help prevent costly repairs in the future.
2. How Important Is Proper Cement Curing for Stucco?
Curing the cement base coat is one of the most critical steps in achieving long-lasting stucco. Here's why:
Prevents Weakness: Proper curing ensures the base coat develops the tensile strength needed to withstand structural movement.
How to Cure Cement Stucco: Certain types of base coats need special curing i.e., watering it 3–4 times a day for 3–4 days, and allow it to set for a minimum of 30 days.
Long-Term Benefits: Proper curing creates a solid foundation that resists cracking and deterioration for decades.
Skipping this step may result in weak, brittle stucco prone to damage.
3. Can You Apply Synthetic Stucco Over Cement Stucco?
While synthetic stucco is a popular and versatile material, applying it directly over cement stucco (color coat) can be a mistake if the proper system is not used. Here's why:
Trapped Moisture: Synthetic stucco can seal in moisture, causing bubbling and peeling.
Base Coat Deterioration: Without a proper substrate, the base coat can weaken over time.
What’s the Right Way to Apply Synthetic Stucco?
Pressure wash (4,000 PSI) the old color coat.
Remove loose stucco/paint.
Re-lath the surface (as needed).
Create a fresh base coat (as needed).
Prime the surface.
Apply a hand troweled synthetic stucco coating.
This ensures a seamless, durable finish that resists common problems.
4. Should You Paint Over Stucco?
Painting stucco might seem like an easy fix, but it can lead to serious problems over time. Here's why:
Paint Traps Moisture: Unlike stucco color coats, some paint is non-porous, preventing moisture from escaping.
Long-Term Damage: Trapped moisture, due to the application of the wrong type of paint can cause bubbling, peeling, and deterioration.
What’s the Alternative to Painting? Instead of paint, opt for a stucco color coat, which allows the material to breathe while maintaining its aesthetic appeal.
Lastly... How Can You Avoid Stucco Problems?
Before hiring a contractor or requesting a stucco estimate, remember this: Anyone can apply a color coat and make it look good, but poorly executed work often leads to significant issues within just 1–5 years.
Save Time and Money: Invest in skilled professionals who use high-quality materials and proven techniques to deliver durable, beautiful results.
Protect your property by hiring experienced stucco experts who ensure your investment lasts for decades.
