How to Sand the Edges of Porcelain Tile

By Mason Howard

Whether tiling a shower wall, kitchen counter or cooktop backsplash, you will probably have to cut a few tiles to fit along edges, in corners and around fixtures. Dense and durable, porcelain tiles do not cut as easily as ceramic tiles. Cut porcelain tiles with an electric wet tile saw, a grinder with a diamond cutting wheel or a special hand nibbler for hard tiles. After cutting, you'll need to smooth the rough or sharp edges.

List of Items Needed

  • Clamp
  • Sanding tool
  • Cloth
  • Sponge
  • Polishing compound
  1. Place the cut tile on a work surface. Position the cut edge of the tile hanging slightly over the edge of the work surface. Safely clamp the tile to the work surface so that the clamp does not damage the tile.

  2. Sand the cut edge of the tile using a coarse grit.

  3. Switch to a slightly finer grit after major rough bits have been removed from the tile's edge. Round the upper corner of the edge if a bullnosed edge is needed.

  4. Finish sanding the edge with an even finer grit.

  5. Wipe down the tile with a damp cloth or sponge to remove any residual sanding dust.

  6. Buff and polish the tile's edge with polishing compound if it will be exposed or not grouted after installation.
