Introduction to Shower Drywall Selection
When it comes to building a shower, choosing the right type of drywall is crucial to ensure durability and moisture resistance. Traditional drywall, often referred to as green board, is ill-suited for wet areas like showers. Instead, cement board or tile backer are the optimal choices. This article will explore the importance of proper drywall selection for showers and highlight why cement board is the best option.
The Perils of Using Traditional Drywall
Green Board, a type of drywall with a water-resistant backing, might seem like a good choice for showers. However, it is actually not suitable. The term resistant is key here; while it can withstand a small amount of water, prolonged exposure will cause it to absorb too much moisture, leading to deterioration. This is particularly true for tiled walls, where green board is often used as a tile backing. Not only will it fail, but it can also contribute to mold growth and other issues that lead to costly repairs.
The Advantages of Cement Board
Cement board, often referred to as Hardibacker, is a moisture-resistant material designed specifically for damp environments. Unlike traditional drywall, cement board does not deteriorate when exposed to water, making it an excellent choice for shower walls. It is commonly used in commercial and residential construction for creating strong, long-lasting shower enclosures. Proper installation of cement board involves cutting and nailing it in place, similar to traditional drywall, but with extra precautions to ensure a watertight seal.
Why Tile Backer is Optimal for Shower Walls
TILE BACKER refers to any moisture-resistant drywall designed for tiled walls, including green board, purple board, and specialized versions. While these materials can be effective, they are not as durable or long-lasting as cement board. The key to successful tile backer installation is following the manufacturer's instructions and ensuring that the edges are as far from the water source as possible. For showers, the ideal choice is cement board due to its superior moisture resistance and durability. Despite its high cost, cement board provides peace of mind knowing that your shower walls will last for years to come without the risk of water damage or mold growth.
Installation Techniques for Cement Board in Showers
When installing cement board for a shower, it is important to follow the proper techniques to achieve a watertight and durable result. Cement board goes up similarly to drywall, using 2-inch roofing nails or screws. However, because of its weight, it is particularly important to support cement board properly, especially on floors. On floors, wood decking must be used to support the cement board, and tar paper must separate it from any wooden substrate. On concrete floors, a smooth finish is all that is necessary before gluing the cement board to the slab.
Conclusion
When it comes to building a shower, selecting the right drywall is crucial. Traditional drywall is not a suitable choice due to its inability to withstand prolonged exposure to water. Instead, cement board or tile backer is the best option for ensuring a long-lasting and watertight shower. By investing in the right materials and following proper installation techniques, you can create a durable and mold-free shower that will provide years of satisfaction and peace of mind.
