Hey there! First, measure your room to know how many square meters of the floor mural you need since it's sold per square meter. You can put it on either the wall or the floor. Just make sure to wipe the surface clean before you start. Hold the sticker up to see the best way to stick it so it looks great. Then, peel the sticker from the bottom of the paper and start sticking from the middle, moving towards both ends. Remember, the mural is waterproof and wear - resistant, but there could be a small color difference because of your monitor. Also, it has seamless splicing, so don't worry about those annoying gaps. For maintenance, just use a damp cloth to clean it if it gets dirty. Enjoy decorating your room with this awesome 3D beach mural!
