Key Points When Doing Exterior Stucco Wall Installation
Stucco, a plaster-like material, is an excellent choice for exterior wall finishes due to its durability, versatility, and timeless appeal. The installation process, though straightforward, requires careful attention to certain key points.
Key Points When Doing Exterior Stucco Wall Installation
Here are some critical steps to consider when installing an exterior stucco wall and stucco homes.
1. Preparation:
Preparation is fundamental to a successful stucco installation. Clear the area around your home where you will be working and protect surrounding surfaces with a drop cloth to prevent stucco splatters.
2. Choosing the Right Stucco:
There are different types of stucco available on the market, each with its unique properties. Traditional stucco is durable but requires a lengthy application process. Synthetic stucco, while easier to apply, might not be as durable. Consider the climate, your home’s architecture, and your personal preference when choosing the right stucco for your home.
3. Wall Inspection:
Inspect the condition of the wall where you plan to apply the stucco. Any existing damage like cracks, moisture issues, or loose material needs to be addressed before you start the stucco installation.
4. Applying a Weather Resistant Barrier:
A weather-resistant barrier is crucial in protecting your home from moisture damage. The barrier should cover all wall surfaces and should overlap at corners and intersections to ensure complete coverage.
5. Installation of Metal Lath:
Metal lath provides a firm grip for the stucco to adhere to. It should be securely fastened to the wall with nails or screws, ensuring that it overlaps by at least one inch at the edges. The rough side should face outward to provide the best grip for the stucco.
6. Mixing Stucco:
Follow the manufacturer’s instructions for mixing the stucco. The consistency should be like that of thick batter. Be cautious not to overmix, as it can weaken the final product.
7. Applying the Scratch Coat:
The scratch coat is the first layer of stucco. Apply it evenly over the metal lath using a trowel and then scratch horizontal lines into the surface to help the next layer adhere better. Allow this coat to cure for about 48 hours (about 2 days).
8. Applying the Brown Coat:
The brown coat, or the second layer, is applied over the scratch coat. This layer should be smoother and more uniform. It needs to dry for 7-10 days before the final coat is applied.
9. Applying the Finish Coat:
The final layer, or finish coat, is where you can get creative. There are many textures and colors you can choose from to give your home the exact look you want.
10. Curing the Stucco:
Proper curing is crucial for the durability of the stucco. Keep the stucco damp for several days after application to help it cure properly and prevent cracking.
11. Regular Maintenance:
Although stucco is durable, it still requires regular maintenance. Check for cracks or other damage annually and make repairs as needed.
