Proper preparation of the concrete surface not only supports a strong bond with the tile but also ensures proper drainage, which is crucial in a wet environment like a shower. Following these steps will lay the groundwork for a successful and durable tile installation.
Step 2: Creating the Proper Slope for Drainage
Creating an effective slope for drainage is a critical aspect of tiling a shower floor. This slope ensures that water is directed towards the drain, preventing stagnation and potential water damage.
- Slope Creation:
- Start by identifying the location of the drain.
- Use a long level to find the high point of the existing concrete floor.
- Determining Slope Angle:
- The ideal slope for a shower floor is about 1/4 inch per foot away from the walls toward the drain.
- This translates to a slope of approximately 2% grade, which is sufficient for effective water drainage.
- Implementing the Slope:
- If your concrete is flat, create a slope using a dry-pack mortar.
- Begin at the walls, building up the mortar bed to the desired thickness, and gently slope it down to the drain.
- Checking the Slope:
- Periodically check your work with a level to ensure the slope is consistent throughout the floor.
- The area around the drain should be the lowest point to encourage proper drainage.
By carefully constructing a slope that directs water efficiently to the drain, you’ll ensure the functionality and longevity of your shower floor. This step is crucial in any shower installation, particularly on concrete surfaces, to prevent water-related complications.
