Flooring Tile - Broken ceramic tile backsplash

I hope this is the right forum!

While removing the old formica countertop (to be replaced with a Silestone top) I broke two ceramic tiles on the backsplash. The pain and suffering of removing an L-shaped countertop is a story for another day!

Luckily, I have replacement tiles. My question is how do I remove the remaining parts of the two broken tiles without damaging the wall and breaking adjacent tiles.

Thanks for the help!

Go to a hardware store and get a grout saw. It's a small handheld tool that has a very rough abrasive looking business end instead of teeth like a conventional saw. Saw the grout out on both sides of the affected tiles. Since you've got the counter top out, come from the bottom of each tile with a flat bar and drive the bar between the wall material and the tile. You will want to be careful not to just jerk it off once it's loose for fear of tearing the sheet rock paper above the tile. If the top of the tile is caulked or stuck to the wall with paint, cut it loose and remove it. Don't worry about it if the wall board behind the tiles gets torn up some. Clean any remaining grout away from the adjacent tiles and scrape any remaining adhesive off the wall areas the tile came from. Mix up a small amount of thinset and stick the replacement tiles up with it. I say thinset for two reasons. It bonds really well to sheet rock and you can use it as a filler if the wall got chunks torn out of it in the removal process. Let the thinset dry, grout and caulk, and stand back and admire your work.
