How To Install? Hanging wall decals is a fun way to engage and interact with your family. We always suggest our customers take a ‘before & after’ photo so you can see just how much you can transform your room! It's so important to start off with a clean and completely dry surface. Things like dirt, dust of fibers can cause adhesion issues and may also limit the amount of times your decal will be re-positionable. Once the surface is clean, dry and you know where it's home will be, peel back a corner of the decal and stick it to the wall. From here, simply peel the backing away smoothing out the decal as you go along. Once on the wall, smooth out any bubbles with your hand and dry cloth making sure it's full adhered ... super easy.
