Stucco Application Process

Stucco application is a complex process that requires special tools and experience. Homeowners with do-it-yourself (DIY) experience may be able to handle stucco application, but others should consider outsourcing installation to stucco contractors. 

If you feel confident in your skills, follow these DIY installation steps:

  1. Prepare the Surface: Prepare the surface by cleaning it thoroughly. Remove dirt, debris, and loose materials, and repair any damages. Dirt and cracks can interfere with adhesion.
  2. Attach a Metal Lath: The metal lath, also called a wire mesh, provides support for the stucco layer. It strengthens the siding against external forces such as impacts or structural movements. You must install the latch carefully to avoid issues with bulging or separation.
  3. Apply the Scratch Coat: The scratch coat is the base coat of stucco, which you apply to the metal latch to help adhere additional layers. It typically consists of Portland cement, sand, and water but may also have other additives. Scratch this layer while it’s still wet to create a rough texture.
  4. Apply the Brown Coat: The brown coat is thicker than the scratch coat and has a different cement, sand, and additives ratio. The brown makes the stucco stronger and more stable.
  5. Apply the Finish Coat: The finish coat determines the texture and appearance of your stucco siding and adds an extra protective barrier against the elements. This coat may include a pigment, which can enhance the aesthetic appeal of your property. After application, the stucco must be kept moist for 48 hours. It takes about 90 days to cure completely.

Advantages of Stucco Finish

Stucco finish remains the most popular choice for United States homeowners, even amid the rising popularity of vinyl, metal, and wood types of siding. See why stucco has remained popular for centuries below.

  • Durability: Stucco’s multiple coat system makes it weather-resistant. It prevents issues such as rot, mold growth, and insect damage. Stucco doesn’t fade easily and maintains a fresh appearance for years, which translates to cost savings for homeowners. 
  • Versatility: Stucco can be applied to a variety of substrates, such as wood, concrete, and masonry. You can choose either traditional or synthetic stucco and paint it with a wide range of colors. Stucco can suit most property designs.
  • Fire Resistance: Stucco is very fire-resistant, which is especially important for houses in fire-prone areas or regions with strict building codes. It also doesn’t emit toxic fumes when exposed to high temperatures.
  • Cost-Effectiveness: Stucco siding typically costs more than other siding materials, such as vinyl, but its impressive longevity and durability make it cost-efficient in the long run.

Disadvantages of Stucco Finish

Stucco finishes do have some downsides. Review the issues you may encounter with different types of stucco below. 

Susceptibility to Moisture Damage

If you don’t properly install and maintain your stucco walls, it may trap moisture against your home’s exterior wall. This can lead to mold growth and structural damage. 

If you don’t properly address cracks in the stucco siding (even hairline cracks), damage can turn into entry points for moisture, leading to water damage expenses. 

Initial Installation Costs  

Stucco has a higher upfront installation cost than other exterior finishes, and the installation is complex. But its return on investment is impressive. 

Possibility of Cracking

Stucco is susceptible to cracking, especially in regions with extreme temperature fluctuations. Inspect the stucco surface regularly and thoroughly to avoid unexpected siding repair costs.


Maintaining Stucco

Stucco maintenance isn’t complicated or time-consuming, but you must be consistent with it. Consider the steps below to keep your stucco strong and stable.

Regular Inspections

Inspect stucco siding at least once per year or before or after harsh weather seasons. Check for the following issues:

  • Cracks and gaps
  • Efflorescence (white powdery residue that indicates moisture intrusion)
  • Staining and discoloration

Pay attention to caulking and sealants around windows and doors. If they start deteriorating, the stucco may lose its ability to repel moisture.

Proper Cleaning and Care

Clean stucco siding with a mild detergent solution and a soft-bristle brush twice a year. Pressure washing may seem like a quick solution for cleaning stucco, but it can damage the surface and force water into cracks. Wash with low pressure or use manual cleaning methods.


Our Conclusion

Stucco is one of the most popular siding options in the country due to its durability, flexibility, aesthetic appeal, and low maintenance. However, the installation process is complex and requires a sizable upfront investment.

If stucco siding fits into your home improvement budget, we recommend making the investment. It can last for as long as you own your property.
