They’re designed for a variety of smooth, finished surfaces, including painted walls, finished wood, painted concrete/cinder block, laminate, glass, metal and tile. Some listings specifically call out concrete for heavier hooks.
Descriptions state the hooks remove cleanly by holding the top of the adhesive strip and pulling it straight down (toward the floor). When removed this way they’re reported to leave no holes, marks, sticky residue, or other damage.
Listings advise cleaning the surface with rubbing alcohol to remove dust and grime, then applying the hook within the recommended indoor temperature range—about 50°F to 105°F—to ensure proper adhesion.
Outdoor hooks are described as weather resistant, with adhesive that can handle temperatures roughly from −20°F to 125°F.
Common recommendations include waiting seven days after painting so paint can cure, avoiding use on wallpaper or hanging over beds, not using the hooks for valuable items, and following the included directions while avoiding any surfaces the listing marks as unsuitable.
