Can You Use Tile Backer Board for Outside Corners?

Tile backer board, a robust and moisture-resistant material, is a popular choice for shower walls and other areas prone to moisture. Its ability to withstand water and provide a solid base for tiles makes it a reliable solution for many projects. However, when it comes to outside corners, the suitability of tile backer board requires careful consideration. While it can be used in some instances, there are specific considerations and alternative methods to ensure a durable and visually appealing result.

Using Tile Backer Board for Outside Corners: Advantages and Limitations

Tile backer board can be used for outside corners, but there are advantages and limitations that must be weighed. One significant advantage is its ability to provide a solid base for tile installation. Its rigid nature helps to prevent the tile from cracking or chipping over time. Additionally, the moisture resistance of tile backer board is crucial for outdoor applications, protecting the wall from water damage. However, the thickness and rigidity of tile backer board can pose challenges when creating a smooth and aesthetically pleasing outside corner.

The primary limitation of using tile backer board in outside corners is the difficulty in achieving a smooth and seamless transition. The straight edges of the board can create a noticeable corner, particularly when the tiles are small or thin. This can result in an uneven and unsightly finish, particularly when compared to the smooth curves achieved with other methods.

Alternative Methods for Creating Outside Corners

For achieving a smooth and aesthetically pleasing outside corner, alternative methods are readily available. One common approach involves using a pre-formed corner bead. These are flexible metal strips with a curved profile, designed specifically for creating smooth outside corners. Corner beads are easily installed and provide a durable base for tile application. Their curved profile eliminates the sharp edges associated with tile backer board, resulting in a more subtle and visually appealing corner.

Another alternative to tile backer board for outside corners is the use of specialized corner systems. These systems typically involve a pre-fabricated corner unit, often made of plastic or metal, that integrates directly into the wall and creates a smooth, finished corner. These systems are designed for both interior and exterior applications and offer a range of design options to complement various tile styles.

Factors to Consider When Choosing a Method

When choosing a method for creating outside corners, several factors should be considered. The size and type of tile, the desired aesthetic, and the budget are all important considerations. For example, if using large format tiles or a minimalist design, a pre-formed corner bead might be the most appropriate solution. Conversely, if working with small tiles or a more decorative style, a corner system could provide a wider range of design options.

The complexity of the project also plays a role. For simple corners, a pre-formed corner bead can provide a cost-effective and straightforward solution. However, for complex projects with intricate designs or unusual angles, a corner system or a more involved approach may be necessary.

Regardless of the chosen method, proper installation is crucial to ensure a durable and aesthetically pleasing result. Adhering to the manufacturer's instructions and using appropriate tools and materials will ensure a successful outcome.
