*This product should be applied by a trained medical professional or for educational training. Always consult a doctor prior to use. Note: A waterproof cast is an alternative to traditional casting materials that cannot get wet. If a traditional cast gets wet, it is ruined and must be removed immediately. However, this does not mean that you can get your waterproof cast wet all day long and not allow a drying period. We recommend that you allow a drying period between wetting times such as bathing or swimming. A hairdryer on a low setting can speed up the process, but body heat needs to evaporate the remaining damp water inside the cast. This allows the patient to get a cast wet, and it not be ruined. But the cast still needs a drying time that will vary by person and cast type between wet periods in order to achieve full dryness.
