Before hanging anything, it’s important to find out what your wall is made of. Ideally, you should attach floating shelves (or anything else you’re hanging) to a wall stud, as this will give you the most supportive base for your project. A stud finder—a hand-held device that uses a magnet to detect metal, such as the nails and screws in the wall studs of your home—can help you locate these.
But what if you want to hang a shelf in a spot with no stud? First, check to see if your wall is made of drywall or plaster. To do this, simply knock with a light fist against the wall. If it sounds hollow, it’s drywall. Not hollow? Probably plaster. Another test is to see how readily a nail goes through. If it slides right in, you’ve got drywall. If it takes a few more taps, then you’ve either got plaster or have found a wall stud (tapping around the sides of the hard area will help you determine which). Knowing the type of wall you’re working with will help you decide what kind of hardware is necessary for your project.
