Stucco is a durable and low-maintenance exterior cladding option commonly used in residential and commercial buildings. However, over time, homeowners may want to update the look of their stucco homes by installing lap siding. The question that arises is whether it is possible to install lap siding directly over stucco. In this article, we will explore the feasibility, benefits, and considerations of installing lap siding over stucco.
Feasibility of Installing Lap Siding Over Stucco
The feasibility of installing lap siding over stucco depends on several factors, including the condition of the existing stucco and the type of lap siding chosen. In general, it is possible to install lap siding over stucco, but it requires proper preparation and adherence to specific installation instructions.
Benefits of Installing Lap Siding Over Stucco
There are several benefits to installing lap siding over stucco. These include:
- Enhanced Aesthetics: Lap siding offers a wide range of design options, allowing homeowners to customize the appearance of their homes. By installing lap siding over stucco, homeowners can transform the look of their properties and add curb appeal.
- Increased Insulation: Depending on the type of lap siding chosen, homeowners can take advantage of the added insulation benefits. Insulated lap siding can help improve energy efficiency and reduce heating and cooling costs.
- Improved Durability: While stucco is undeniably a robust cladding option, lap siding can provide an extra layer of protection against the elements. Lap siding is designed to withstand various weather conditions, including wind, rain, and sun exposure, potentially improving the lifespan of the exterior wall.
Considerations for Installing Lap Siding Over Stucco
However, before deciding to install lap siding over stucco, several considerations need to be taken into account:
- Condition of the Stucco: The condition of the stucco is crucial for the success of the lap siding installation. If the stucco is in poor condition, cracked, or has significant damage, it may be necessary to repair or replace it before proceeding with the lap siding installation.
- Moisture and Ventilation: Moisture management is essential in any exterior siding system. When installing lap siding over stucco, careful attention must be paid to moisture control to prevent water infiltration and potential damage to both the stucco and new siding. Proper ventilation should also be considered to prevent moisture buildup behind the siding.
- Compatibility of Materials: It is essential to ensure that the selected lap siding and stucco are compatible in terms of material composition and expansion/contraction rates. Consulting with professionals or manufacturers can help determine the compatibility of the materials.
Installation Process
To install lap siding over stucco, the following general process should be followed:
- Preparation: Thoroughly clean the stucco surface, removing any dirt, debris, or loose material. Repair any cracks or damage in the stucco as needed.
- Weather Barrier: Install a weather barrier, such as house wrap, to create a moisture barrier between the stucco and new siding. The weather barrier should be properly fastened and sealed to provide maximum protection.
- Furring Strips: Install horizontal furring strips vertically or horizontally over the weather barrier to create an air gap between the stucco and new siding. These strips provide ventilation and allow for proper drainage of any moisture that may accumulate.
- Lap Siding Installation: Follow the manufacturer’s instructions for installing the chosen lap siding over the furring strips. Pay attention to the recommended fastening methods, expansion gaps, and proper sealing techniques.
It is possible to install lap siding over stucco, but careful consideration and proper preparation are crucial. By taking into account the condition of the stucco, moisture management, compatibility of materials, and following the correct installation process, homeowners can successfully update the appearance of their stucco homes while adding durability and insulation benefits with lap siding. Consulting with professionals or manufacturers can provide valuable guidance throughout the installation process.
