This is my 2nd time around with smart tiles for our kitchen backsplash. The brown mosaic we installed about 10 years ago, and they looked good as new the day we took them down. We were just looking for an update, and didn’t want to spend a ton. We decided to go with smart tiles again, and I’m so happy we did! It took less than an hour to remove the old tiles, and only a couple hours to put the new ones up. Such a great DIY solution!
