Mag-Bloks should ideally be mounted into a stud or solid surface. When mounting to drywall with no stud available you must use drywall anchors. We like the E-Z Anchor style. Mounting to ceramic or stone surfaces can be done a few different ways. You can, of course use anchors again. If you'd prefer not to drill, though we don't officially endorse it, some of our customers have had good results using 3M VHB (Very High Bond) mounting tape (other brands have similar products). We cannot, however, vouch for its use. Do so at your own risk.
