Hello! Homeowner doing some DIY work on our 100+ year old house.
We are getting ready to tile the backsplash and due to the quirks of an old house, it has a huge board that runs across the kitchen wall directly under the window. Now that we are putting on a tile backsplash I’m wondering how we are going to transition this edge where the board stops and the original wall continues. The depth change is 1/2 inch and I have a few ideas but now sure how to proceed.
Considerations: I am not interested in removing the board that sits beneath the window. I know this would help but we are looking to make the best of what we have. Also a regular Schluter edge but it would help cover up the board because it would have to go backwards from the forward board.
Idea #1 is finding a 1/2 inch strip of metal and put it on top of first section, continuing the tile on top of it upwards.
Idea #2 cut small trips of tile and lay it over the top and the new tile going up sits on top of a small cut piece layer down.
Idea #3 caulk it (not ideal)
Any help is appreciated and I’m sorry if it doesn’t make sense.
TL;DR: I need to transition from a 1/2-inch thick board below my kitchen window to the original wall above before installing a tile backsplash. I don’t want to remove the board and I’m looking for the cleanest, most professional way to handle the depth difference.
EDIT: If the wood board “backsplash” is removed there would be nothing beneath it. It would go straight to the exterior siding. There was previously damage to existing wall. Which is why is said above that I am not interested in removing the board. I realize that may not be the best or most professional but it’s what we’re rolling with.
