Using these 3D wall and ceiling murals is easy. First, pick a place in your home where you want to put the mural and wipe it clean to ensure good adhesion. Hold the mural in your hands and think about how to stick it so that it looks great. Then, peel the backing from the bottom of the paper and start from the middle, sticking it out towards both ends. Remember, the patterns of wall and ceiling murals are different, so if you want both, you need to buy them separately. As for maintenance, since they are waterproof, a little water won't harm them. But try to keep them away from sharp objects to avoid scratches. Also, because of possible differences in monitor settings, the color on your screen might be a bit different from the real mural, so don't be surprised if there's a slight variation.
