Unlike medicated plasters, zinc oxide tapes are not meant for cuts or wounds. Rather, these are rigid and highly adhesive plasters. They are waterproof to some extent and don’t come off easily. Zinc oxide tapes are more common in sports and physiotherapies. Basically, these tapes can be used to restrict movement. In order to restrict movement, however, zinc oxide tapes should be applied around joints. You can wrap it around knuckles to restrict the movement of an injured finger, or wrists. You have to choose the size of the plaster depending on where you want to use it. Larger joints require the use of a wider plaster.
