Can I Tile Over Tile Shower Floor?
It's a common question for homeowners tackling a shower renovation: Can I tile over existing tile? The answer, unfortunately, isn't a simple yes or no. It depends on a few factors, including the condition of the existing tile and the type of tile you're planning to install.
Here's a breakdown of the pros and cons:
Pros of Tiling Over Tile:
- Saves Time and Money: Tiling over existing tile can be a quicker and less expensive option than removing the old tile, especially if you're a DIY enthusiast.
- Minimal Dust and Debris: Removing existing tile can create a significant mess, whereas tiling over it minimizes dust and debris.
- Adds Thickness: If your shower floor is slightly uneven, adding a new layer of tile can help level it out.
Cons of Tiling Over Tile:
- Potential Adhesion Issues: If the existing tile isn't securely attached to the subfloor, the new tile might not adhere properly, leading to cracking or delamination.
- Uneven Surface: If the existing tile has significant unevenness or grout lines, the new tile might not lay flat.
- Weight: Adding another layer of tile can add significant weight to the floor, which might not be suitable for all structures.
When It's a Bad Idea:
- Cracked or Loose Tiles: If the existing tile is cracked, chipped, or loose, it's best to remove it before installing new tile.
- Water Damage: If the existing tile has water damage or signs of mold, removing it is essential to prevent further issues.
- Uneven Surface: If the existing tile has significant unevenness or is not level, removing it is the best option to ensure a smooth and even surface for the new tile.
What to Do Before Tiling Over Tile:
- Inspect the Existing Tile: Carefully inspect the existing tile for cracks, chips, loose tiles, and signs of water damage.
- Check for Grout Issues: Inspect the grout for cracks and missing sections.
- Test Adhesion: Tap on the existing tile to check its adhesion. If it sounds hollow, it might be loose and needs to be removed.
- Clean the Surface: Thoroughly clean the existing tile with a degreaser to remove dirt, grime, and soap residue.
If you decide to tile over tile, it's essential to use a high-quality mortar designed for this purpose. Consult with a professional if you're unsure about the condition of your existing tile or the best course of action.
