- Smooth out any excess adhesive to create a flat and even surface.
- Allow the thin-set adhesive to dry completely before moving on to the next step.
Waterproofing Sealer Application Process
After taping the seams and corners, it is essential to apply a waterproofing sealer to the shower walls. This step adds an additional layer of protection against moisture, ensuring the longevity of the tile installation.
To apply the sealer:
- Pour the waterproofing sealer into a paint tray.
- Using a roller brush or a paintbrush, apply the sealer evenly across the backer board.
- Start from the top and work your way down.
- Be sure to cover the entire surface, including the seams and corners.
- Allow the sealer to dry completely before proceeding with the tile installation.
Why Drywall is Not Suitable For Shower Walls
Using drywall as a substrate for tile on tub or shower walls is not recommended due to its poor resistance to moisture. Drywall is susceptible to water damage, which can lead to mold growth and structural issues. To ensure the durability of the tile installation, it is crucial to use cement backer board instead.
Drywall cannot provide the necessary waterproofing and stability required for wet areas like bathrooms and showers. Therefore, it is important to follow the recommended steps for proper tile installation:
- Use cement backer board as the substrate for the tiles.
- Tape the seams of the backer board to prevent moisture penetration.
- Apply a waterproofing sealer over the backer board before tiling.
Note: The use of cement backer board and proper waterproofing measures are essential to prevent water damage and ensure the longevity of the tile installation.
Varying Steps For Wall Preparation
The steps for preparing shower walls for tile can vary depending on the surface of the wall. It is important to customize the preparation process based on the specific wall material to ensure a successful tile installation.
Before tiling, take the time to remove any screws, photo hooks, nails, or other fittings from the walls. If there is loose plaster, it should be removed, and any cracks or holes should be filled. Check the wall’s levelness using a long, flat piece of timber, and sand down any bumps over 4-5mm.
Different surfaces such as concrete, drywall, plywood, and painted surfaces require specific preparation techniques. Additionally, fresh plaster needs sufficient time to dry, and wooden surfaces should be primed. It is always recommended to consult with a professional to ensure the correct preparation steps are followed for each specific surface.
Preparing Different Surfaces For Tile Installation
Depending on the wall surface material, specific preparation techniques are required before tile installation can occur. Here is a breakdown of the necessary steps for common surfaces:
-
Concrete: Ensure the surface is clean and free of debris. Repair any cracks or unevenness with a concrete patching compound. Apply a bonding agent to enhance adhesion.
-
Drywall: Leave fresh plaster to dry for at least a month. Apply a rough texture to the wall to promote better tile adhesion. The surface should be clean, and free of dust and particles.
-
Plywood: Plywood is generally not recommended for wall tiling due to its sensitivity to temperature changes and potential damage to tiles and grout. If it must be used, apply a layer of cement backer board as a substrate for tiling.
-
Painted Surfaces: Remove loose paint, fill cracks and holes, and clean the surface with TSP or an ammonia-based cleaner. Ensure the surface is dry, dust-free, and grease-free.
