How are you? The scale of tile might be a bit large for use as a backsplash. The material is a fiber so direct contact with water is not recommended. I have seen them used this way so it can be done. We recommend sealing the tiles front and back with multiple primer coats before installing into an area like this. Then you would follow the standard installation instructions from there. Hope this helps and please let us know if we can answer any additional questions or be of help in any way.
