However, it’s important to understand the process and techniques involved in order to achieve quality results. In this article, we’ll walk through the steps for installing backsplash tile over tile, from assessing your existing tile to prepping the surface and laying the new tiles.

Assessing the Existing Tile

The first step is to evaluate the current state of the tile and determine if it’s suitable for tiling over. Here’s what to look for:

  • Loose tiles – Use painter’s tape and thinset mortar to secure any loose or hollow-sounding tiles.
  • Cleanliness – Scrub away any built up grease, soap scum, or other residues. Mildew should also be treated.
  • Moisture – Identify any areas of moisture damage or leaks and resolve before retiling.

If the existing tile is generally in good shape with only minor issues, it likely makes a suitable base for new thinset and backsplash tiles.

Preparing the Tile Surface

Once you’ve determined the existing tile is salvageable, the next step is prep work. Here are the key tasks:

  • Roughen smooth tiles – Use 60-80 grit sandpaper to scuff up any glossy tile finish so the thinset can bond properly.
  • Fill grout lines – Spread thinset over the grout with a trowel to level it with the rest of the tile.
