Hey there! Using these awesome floor murals is a breeze. First, measure your room to figure out how many square meters you need because the price is for one square meter. Then, pick a spot on the wall or floor, give it a good wipe to make sure it's clean. Before sticking, hold the sticker up to see how it'll look on the surface. When you're ready, start from the bottom of the paper and peel off the sticker. Place it in the middle of your chosen area and then smooth it out towards both ends. One thing to remember is that if you order a size longer than 1.2 meters, the mural will be cut because of shipping rules. Also, don't be surprised if there's a tiny color difference between what you see on the screen and the real mural due to monitor settings. As for maintenance, since these murals are waterproof and wear - resistant, a simple wipe with a damp cloth should keep them looking great for a long time.
