When it comes to installing tile in various parts of your house, such as kitchens, bathrooms, or even outdoor spaces, using a backer board is crucial. A backer board is a type of material that provides a stable and sturdy surface for tile installation, ensuring its long-lasting and durable performance. However, not all backer boards are created equal, and different areas of your house may require specific types of backer boards. In this article, we will discuss the various types of backer boards available and which ones are suitable for different parts of a house.
1. Cement Backer Board
Cement backer board is one of the most common types used for tile installation. It consists of a mixture of cement and reinforcing fibers, providing excellent strength and moisture resistance. Cement backer boards are typically used in areas prone to moisture exposure, such as bathrooms and showers. They are also suitable for outdoor installations. The cement construction prevents water damage, ensuring the longevity of your tile installation.
2. Fiber Cement Backer Board
Fiber cement backer boards are similar to cement backer boards but with the addition of cellulose fibers. These fibers enhance the board’s flexibility while maintaining its strength. Fiber cement backer boards are ideal for areas with slight movement or floor deflection, making them suitable for upper-level installations or floors with wooden subfloors. They also offer excellent resistance to moisture, making them suitable for bathrooms and kitchens.
3. Gypsum Backer Board
Gypsum backer boards, also known as drywall tile backer boards, are made from gypsum plaster and encased with fiberglass mats on both sides. These boards are lightweight and easy to handle, making them a preferred choice for walls rather than floors. Gypsum backer boards are ideal for areas where moisture exposure is limited, such as kitchen backsplashes or fireplace surrounds. However, using them in wet areas like showers is not recommended as they are not as moisture-resistant as cement backer boards.
4. Cementitious Wood Fiber Backer Board
Cementitious wood fiber backer boards are specifically designed for tile installation over wooden subfloors. These boards are made from wood fibers mixed with cement, providing both stability and moisture resistance necessary for tile installation. They are often used in areas with floor deflection or uneven subfloors. Cementitious wood fiber backer boards are commonly used in kitchens, laundry rooms, and other areas with wooden subfloors.
5. Exterior Sheathing
In some cases, exterior sheathing boards can be used as backer boards for outdoor tile installations. These boards are mainly used for waterproofing and insulating the exterior walls of a house. Their inherent moisture resistance and durability make them suitable for outdoor tile installations, such as patios, pool decks, or walkways. However, it is essential to ensure that the selected sheathing board is compatible with tile installation before proceeding.
There are various types of backer boards available for different parts of a house. Cement backer boards are commonly used in areas prone to moisture exposure, such as bathrooms and showers, while fiber cement backer boards are suitable for areas with slight movement or wooden subfloors. Gypsum backer boards are ideal for limited moisture areas like kitchen backsplashes, and cementitious wood fiber backer boards are specifically designed for tile installation over wooden subfloors. Additionally, exterior sheathing boards can be used for outdoor tile installations. Choosing the right type of backer board ensures a successful tile installation that will withstand the test of time.
