• Yes you can get your waterproof cast wet if your Hand Physiotherapist has told you. You should allow the cast and your skin to dry thoroughly before getting the cast wet again.

• Drying time for casts will vary. Most casts will feel dry in one hour.

• Parents or guardians of young children should monitor the condition of the cast and skin under the cast after the child has gotten the cast wet.

• Gravity causes the water to drain from the cast. If your cast is wet, it is important to position your cast so that water will drain out. Arm cast: Hang arm downward and drain from end of cast.

• Ensure that you rinse out the cast thoroughly with clean water after swimming.

• For your safety when swimming, deep water should be avoided.
