Why Choose Stucco?

Stucco is a versatile and durable material that offers a unique aesthetic appeal. It's known for its ability to enhance the appearance of any home while providing a robust protective layer. Many homeowners opt for stucco because it is both weather-resistant and low-maintenance, making it a wise investment.

Preparing Your Home for Stucco

Before applying stucco over siding, it's essential to prepare the surface properly. Start by inspecting the current siding to ensure it's in good condition. Any damaged or rotten areas should be repaired or replaced. This step is crucial as it ensures the longevity of the stucco application.

Cleaning the Siding

Thoroughly clean the siding to remove dirt, grime, and any loose paint. This can be done using a pressure washer or a scrub brush with a suitable cleaning solution. Ensure the surface is completely dry before proceeding to the next step.

Application Process

Once the siding is prepped, you can begin the stucco application. This typically involves applying a layer of building paper and galvanized metal lath over the siding. The building paper acts as a moisture barrier, while the metal lath provides a surface for the stucco to adhere to.

Mixing and Applying Stucco

Mix the stucco according to the manufacturer's instructions. It's important to achieve the right consistency to ensure a smooth application. Apply the first coat, known as the scratch coat, using a trowel. Once it has set, scratch the surface to create grooves for the next layer to adhere.

Finishing Touches

After the scratch coat has dried, apply the second layer, known as the brown coat. This layer should be smooth and even. Once it has cured, you can apply the final layer, the finish coat. This is where you can add texture and color to match your desired aesthetic.

Curing and Maintenance

Allow the stucco to cure properly by keeping it moist for several days. This helps prevent cracks and ensures a durable finish. Once cured, stucco requires minimal maintenance. Regular inspections and occasional cleaning will keep it looking fresh for years.

Benefits of Stucco Over Siding

By applying stucco over siding, you not only enhance your home's curb appeal but also increase its energy efficiency. Stucco acts as an additional layer of insulation, helping to regulate indoor temperatures and reduce energy costs.

Transforming your home with stucco is a rewarding project that adds value and beauty. With the right preparation and application, you can enjoy a stunning exterior that stands the test of time.
