Installing a travertine bullnose backsplash to your wall is similar to tiling your floor, but seemingly more difficult because of the angle in which you will be working. The end result, however, will be much worth the new decorative accent to your home.
Step 1 - Get Materials, Measure and Prepare Wall
Purchase the matching type of travertine bullnose tile you would like to create your backsplash along with a type of grout color that will go well with travertine tile. If the wall you are doing the backsplash on is simply painted drywall then all you have to do is sand the drywall smooth and you can construct it right on top.
If there is already a backsplash then you need to remove both the backsplash and drywall underneath, then replace it with new drywall. Also measure the length and width of the wall you will be placing the backsplash. Depending on the size of the tile you get it is easiest to use a piece of graph paper to use your measurements to plan out the pattern of the backsplash.
This will help with planning for the amount of tiles you will need and the edges of the backsplash when you need to cut tiles. Then, before you start, remove anything that will be in your way like electrical cover plates or light fixtures.
Once this is done then place the cement backerboard onto the drywall using the screwdriver and screws. Make sure you cut around electrical outlets or other fixtures in the wall. Don't put the backerboard end to end. Instead leave a 1/8 inch gap then use mesh tape and filler compound in those gaps.
