Hey there! Using these waterproof 3D floor murals is a breeze. First, measure your room to figure out how many square meters you need as the price is for 1 square meter only. Pick a spot on the wall or floor, and give it a good wipe to make sure it's clean. Hold up the sticker to see how it looks best before sticking. Then, start peeling from the bottom of the paper and apply it from the middle to both ends. Remember, these murals have seamless splicing. When it comes to maintenance, since they're waterproof and wear - resistant, just a simple wipe with a damp cloth should do the trick. And keep in mind that the color on your screen might be a bit different from the actual mural because of monitor settings.
