Can synthetic (fiberglass) casts get wet?
Although the fiberglass itself is waterproof, the padding inside a fiberglass cast is not. So it’s still important to try to keep a fiberglass cast from getting wet. If this is a problem, talk to the doctor about getting a waterproof liner. Fiberglass casts with waterproof liners let kids continue bathing or even go swimming during the healing process. Although the liner allows for evaporation of water and sweat, it’s still fragile. Also, only certain types of breaks can be treated with this type of cast. Your doctor will determine if the fracture may be safely treated with a waterproof cast.
