The Importance of Regular Stucco Maintenance on Commercial Buildings

by | May 13, 2024 | Stucco

Stucco is a material known for its timeless charm and robust durability, making it a popular option for commercial building exteriors. However, just like any aspect of a building, stucco needs regular maintenance to retain its appeal and functionality. It’s common for building owners and property managers to feel unsure about how to properly care for stucco.

To assist you in maintaining the condition of your stucco and keeping its visual appeal and functionality, we have compiled the following tips.

Routine Stucco Cleaning and Inspection

Regular cleaning and inspection are the foundation of effective stucco maintenance. Keeping the stucco on your commercial property clean enhances its visual appeal and helps prevent potential issues such as mold and mildew.

 

  1. Schedule periodic cleanings to remove dirt, grime, and organic buildup. Use a garden hose or low-pressure power washer to gently wash the stucco surface with water and a mild detergent or stucco cleaner. Be cautious when using high-pressure power washers, as they can potentially damage the stucco surface.

 

  1. Conduct routine visual inspections for signs of damage, cracking, or wear. Look for any moisture issues, discoloration, or mold growth that could signal underlying problems.

 

Protecting Stucco From Moisture Damage

Moisture intrusion is one of the primary causes of stucco failure. Properly sealing and protecting stucco from moisture is key to preserving its performance and longevity.

 

  1. Inspect and repair any potential sources of moisture intrusion, such as roof leaks, gutter problems, or plumbing issues.

 

  1. Assess the integrity of your stucco’s sealant and flashing. Regularly reseal any gaps or cracks around windows, doors, and other openings, and replace damaged or worn flashing as needed.

 

  1. Ensure that your commercial building has proper drainage systems that effectively redirect water away from its foundation. This will help reduce the risk of water seepage and potential damage to the stucco.

 

Addressing Cracks in Stucco

Cracks in your stucco can occur due to typical building settling or fluctuations in temperature. Addressing these issues promptly can help prevent further damage to your stucco exterior.

 

  1. Hairline Cracks: For small hairline cracks, use a high-quality acrylic or silicone caulk rated for use on exterior stucco surfaces. Apply a thin bead of caulk into the crack, then smooth it out and feather the edges using a damp sponge or your finger. Allow the caulk to dry and cure according to the manufacturer’s instructions.

 

  1. Larger Cracks: For larger stucco cracks, additional repair steps may be necessary. First, use a cold chisel or scraper to remove any loose or damaged stucco around the crack. Next, apply a stucco repair compound to the area, following the manufacturer’s instructions and blending it with the existing stucco texture. Allow the repair compound to dry and cure before painting or sealing the repaired area.

 

Repainting and Resealing Stucco Exterior

Refreshing your stucco’s paint and sealant can extend its lifespan and improve its visual appeal. Here’s how to do it properly:

 

1. Prepare the Surface:

Before repainting, ensure the stucco surface is clean and free of any loose paint, debris, or contaminants. Use a wire brush or power washer to remove any peeling or flaking paint.

 

2. Apply a Primer:

A high-quality acrylic or masonry primer can provide an ideal base for your paint and enhance its adhesion to the stucco surface. Make sure the primer is compatible with your stucco and chosen paint product.

 

3. Choose the Right Paint:

Select a paint product specifically designed for stucco surfaces. Look for 100% acrylic or elastomeric paint, as these types provide excellent durability and flexibility.

 

4. Apply the Paint:

Use a roller, brush, or spray applicator to apply the paint to your stucco exterior, following the manufacturer’s recommendations for coverage and drying times. Typically, two coats of paint are required for optimal coverage and protection.

 

5. Reseal your Stucco:

After repainting, consider applying a high-quality waterproof sealer or masonry sealant to provide additional protection against moisture intrusion.

 

Preventing Mold, Mildew, and Efflorescence

 

Mold, mildew, and efflorescence can mar the appearance of your stucco exterior and indicate potential underlying issues. Here are tips for preventing these unsightly problems:

 

  1. Ensure proper ventilation and moisture control throughout your commercial property. This is especially important in areas prone to dampness or high humidity, such as kitchens, bathrooms, and basements.

 

  1. Address any plumbing, roofing, or gutter issues that could cause excess moisture infiltration into your stucco.

 

  1. Periodically clean your stucco exterior with a mildewcide- or fungicide-treated cleaning solution to prevent mold, mildew, or algae growth.

 

  1. If efflorescence forms on your stucco surface, remove it with a diluted white vinegar and water solution, followed by a clean water rinse. Address any issues causing excess moisture infiltration to prevent efflorescence from reoccurring.
