Can You Use Tile Backer Board Outside of Shower Walls In Virginia?

Tile backer board, also known as cement board or backer board, is a popular substrate for tile installations in wet areas such as showers and bathrooms. Its moisture-resistant properties make it an ideal choice for these applications. However, can tile backer board be used outside of shower walls in Virginia? This article explores the essential aspects of using tile backer board in exterior settings.

Understanding the Purpose and Benefits of Tile Backer Board

Tile backer board is designed to provide a stable and moisture-resistant base for tile installations. It is typically made from a mixture of cement, sand, and fiberglass fibers, creating a strong and durable material. Tile backer board offers several benefits, including:

Moisture Resistance: Backer board's non-porous nature prevents moisture from penetrating the substrate, reducing the risk of damage or mold growth.
Stability: It provides a solid and stable base for tile installations, preventing tiles from cracking or becoming loose.
Flexibility: Backer board can be cut and shaped to fit irregularly shaped surfaces.

Using Tile Backer Board Outside of Shower Walls in Virginia

While tile backer board is primarily used in wet areas, it can also be suitable for exterior applications in Virginia. However, certain factors need to be considered:

Moisture Management: Exterior surfaces are exposed to moisture from rain, snow, and humidity. Ensure proper drainage and ventilation to prevent water accumulation behind the backer board.
Freeze-Thaw Cycles: Virginia experiences freeze-thaw cycles, which can cause water to penetrate the backer board and expand, leading to damage. Use a backer board specifically designed for exterior use and install it according to the manufacturer's guidelines.
Extreme Heat: Prolonged exposure to high temperatures can cause the backer board to warp or crack. Choose a heat-resistant backer board if the area receives direct sunlight.

Selecting and Installing Tile Backer Board for Exterior Applications

When selecting tile backer board for exterior use, look for products specifically designed for this purpose. These backer boards typically have higher moisture resistance and freeze-thaw durability. Follow the manufacturer's installation instructions carefully:

Subsurface Preparation: Ensure the substrate is clean, dry, and free of any contaminants.
Backer Board Installation: Install the backer board according to the manufacturer's guidelines, using appropriate fasteners and avoiding gaps or overlaps.
Sealing and Waterproofing: Apply a waterproofing membrane or liquid-applied waterproofing product over the backer board to enhance moisture protection.

Conclusion

Tile backer board can be used outside of shower walls in Virginia, provided certain considerations are taken into account. By using an exterior-grade backer board, ensuring proper moisture management, and following the manufacturer's installation instructions, you can create durable and moisture-resistant tile installations that enhance the aesthetic appeal of your outdoor spaces.
