How To Do Stucco Trim Around Windows

Adding stucco trim around windows can greatly enhance the overall appearance and curb appeal of your home. Stucco trim not only provides a decorative touch, but it also helps to protect the edges of your windows from moisture and wear. While stucco installation may seem like a daunting task, with the right tools and a little know-how, you can easily achieve professional-looking results. In this article, we will guide you step-by-step on how to do stucco trim around windows, ensuring a successful project that will add beauty and value to your home.

Materials and Tools Required:

Before diving into the steps, it’s crucial to gather all the necessary materials and tools to ensure a smooth and efficient process. Here’s a list of what you’ll need:

• Stucco mix
• Metal lath
• Scratch coat hammer
• Trowel
• Bucket for mixing stucco
• Wire snips
• Nails
• Tape measure
• Straight edge
• Miter saw or circular saw
• Level
• Caulk
• Paint or sealant

Step 1: Preparation:

Before applying the stucco, it’s crucial to prepare the windows and the surrounding area.

Measure and Cut:

Start by measuring the width and height of each window opening to determine how much trim you will need. Add an extra inch to each dimension to allow for any inconsistencies. Using a miter saw or circular saw, cut the metal lath strips into sections that match the height and width of your windows.

Prepare the Window:

Clean the window frame and remove any dirt or loose paint. Apply a bead of caulk around the window frame, sealing any gaps or cracks. This will help create a watertight seal between the window and the stucco trim.

Step 2: Install Metal Lath:

The metal lath provides a secure foundation for the stucco to adhere to. Follow these steps to install the metal lath:

Attach the Lath:

Starting at the bottom of the window, position the first section of metal lath against the window frame. Use nails to secure it in place, ensuring it is snug against the frame. Repeat this process for the remaining sides of the window, overlapping the edges of each section of metal lath by at least 2 inches.

Secure the Lath:

Use wire snips to trim the excess metal lath, making sure the edges are flush with the window frame. Be careful when handling the sharp edges of the metal lath. Once trimmed, fasten the lath to the window frame every 6 inches using nails.

Step 3: Apply the Scratch Coat:

The scratch coat provides a rough textured surface for the final layer of stucco to adhere to. Follow these steps to apply a scratch coat:

Mix the Stucco:

Refer to the manufacturer’s instructions to mix the stucco mix correctly. Use a bucket and a trowel to combine the stucco mix with the required amount of water. Mix thoroughly until you achieve a smooth, paste-like consistency.

Apply the Scratch Coat:

Using a trowel, apply a thin layer of stucco onto the metal lath, starting at the bottom of the window. Spread the stucco evenly, ensuring a consistent thickness of about 1/4 inch. Work your way up to cover the entire metal lath. Use a scratch coat hammer or a notched trowel to create horizontal ridges in the stucco. This will help the final layer of stucco adhere properly.

Step 4: Finish Coat:

The finish coat provides the final decorative layer and should be applied after the scratch coat has dried. Here’s how to apply the finish coat:

Mix the Stucco:

Prepare another batch of stucco mix, following the same instructions as before. It’s essential to mix enough stucco to complete the entire trim project, as color variations can occur between different batches.

Apply the Finish Coat:

Using a trowel, apply the final layer of stucco onto the scratch coat. Spread the stucco evenly, ensuring a consistent thickness of about 1/8 inch. Smooth the stucco surface with a trowel or float, working from bottom to top. Double-check for any imperfections or uneven spots and make adjustments accordingly.

Step 5: Finishing Touches:

Once the stucco has dried, it’s time to add the finishing touches to complete the stucco trim around your windows.

Seal and Paint:

Apply a high-quality paint or sealant to protect the stucco trim and enhance its appearance. Choose a color that complements your home’s exteriors for a cohesive look. Ensure the paint or sealant is designed for exterior use and follows the manufacturer’s application instructions.

Clean Up:

Clean up any debris or excess stucco from the surrounding areas once the project is complete. Dispose of the waste material responsibly and admire your newly enhanced windows.
