Understanding Stucco Cracks:

Stucco cracks can occur for various reasons, including:

Visible cracks in Stucco
  • Settling

    As a home settles, minor cracks may develop. These are usually hairline cracks and are a common occurrence in many properties.

  • Moisture

    Water infiltration can lead to cracks as stucco expands and contracts with moisture exposure.

  • Impact

    Physical impacts, such as from a lawnmower or a wayward baseball, can cause cracks or dents in the stucco.

Materials and Tools You’ll Need

Before you begin repairing stucco, gather the following materials and tools:

  • Stucco Mix

    Match this to the existing stucco texture and color.

  • Trowel and Floats

    Essential for applying and smoothing the stucco.

  • Bonding Agent

    Helps the new stucco adhere to the old surface.

  • Bucket and Mixing Paddle

    For preparing the stucco mix.

  • Painter’s Tape

    To protect adjacent surfaces.

  • Safety Gear

    Including safety glasses and gloves.

Prepare the Surface

Clean the damaged area of loose stucco, dirt, and debris.

If there are cracks, use a wire brush or chisel to open them up slightly, creating a V-shaped groove. This helps the new stucco adhere better.

Apply Bonding Agent

Brush a bonding agent onto the cleaned and prepped surface. This helps the new stucco bond to the existing stucco.

Mix the Stucco

Follow the manufacturer’s instructions to mix the stucco. It should have a consistency similar to peanut butter.

Apply the Stucco

Using a trowel, apply the stucco mixture to the damaged area. Fill the crack or damage evenly, slightly overfilling to allow for shrinkage as it dries.

Texture the Stucco

Match the texture of the surrounding stucco using a float or other texturing tools. This step requires some skill to achieve a seamless look.

Let It Cure

Allow the repaired stucco to cure according to the manufacturer’s instructions, typically for several days.

Paint or Finish

Once the repaired area is fully cured, you can paint or finish it to match the rest of the stucco.

Stucco’s energy efficiency benefits are not only good for the environment but also for your wallet. Lower energy bills, increased comfort, and reduced reliance on heating and cooling systems all add up to long-term savings.
