Can You Put Tile Over Drywall In Shower?

Tiling a shower over drywall is a popular and cost-effective method to update or remodel your bathroom. However, it's essential to approach this project with the proper knowledge and preparation to ensure a successful and durable installation.

1. Substrate Preparation

Drywall is not a suitable substrate for direct tile application. It is prone to moisture damage and cannot withstand the weight and stress of tiling. Therefore, you must prepare the drywall by installing a backer board.

2. Choosing the Right Backer Board

Backer boards provide a stable and water-resistant surface for tiling. There are two main types of backer boards: cement board and waterproof drywall.

* Cement board: A durable and moisture-resistant material that is ideal for shower applications. * Waterproof drywall: A gypsum-based board treated with a moisture-resistant coating. It is less durable than cement board but is easier to cut and install.

3. Installing the Backer Board

Follow these steps to install the backer board:

* Cut the backer board to the desired size. * Apply thin-set mortar to the drywall and press the backer board into place. * Secure the backer board with screws, spaced every 6-8 inches apart. * Allow the thin-set to dry completely before proceeding.

4. Waterproofing the Backer Board

To provide additional protection against moisture, apply a waterproofing membrane over the backer board.

* Choose a liquid membrane specifically designed for shower applications. * Apply the membrane according to the manufacturer's instructions, ensuring it covers all seams and joints. * Allow the membrane to dry completely before tiling.

5. Tiling the Shower

Once the backer board is waterproofed, you can begin tiling the shower.

* Apply a layer of thin-set mortar to the back of each tile and press it into place. * Use tile spacers to ensure even spacing. * Grout the joints between the tiles and allow it to dry completely.

6. Sealing the Shower

After grouting, apply a silicone-based sealant around the edges of the shower, including where the tile meets the walls and fixtures.

* Use a high-quality sealant that is mold and mildew-resistant. * Smooth the sealant with your finger or a damp cloth. * Allow the sealant to cure completely before using the shower.

Conclusion

Tiling a shower over drywall requires proper preparation and adherence to specific techniques to ensure a successful and durable installation. By following the steps outlined above, you can transform your bathroom into a beautiful and water-resistant space.
