Most standard casts consist of two parts: a fiberglass covering and cotton padding underneath. The fiberglass is water resistant and won’t fall apart if it gets wet. The cotton padding inside, however, must be kept dry. Knowing how to waterproof a cast can come in handy when you want to take a shower or go swimming with a cast and here are three ways you can do it on your own as explained by our team here at AquaCast Liner.
1. Purchase a Cast Cover
Cast covers fit over the cast and fasten with a watertight seal. They usually take the form of a long plastic sleeve that can slide over an arm or leg cast. The opening has a plastic gasket that fits tightly against the skin to keep water out. Some covers include a pump to suck out air from inside the cover. They are completely waterproof and make it possible to go swimming with a cast. Most cast covers are reusable. They can be purchased in a drug store or online.
We recommend you keep an eye on the seal if you are active or swimming to make sure the it is tight and you do not see any water entering the cover. If you do, then we suggest you quit swimming immediately to check the cover seal and make sure no water has come in contact with the cast padding.
2. Use Plastic Bag & Tape
Plastic bags and tape are not as handy as a cast cover, but will work to keep your cast dry, for the most part. Slide a small garbage bag, a plastic newspaper bag or a grocery bag over the cast. Seal the opening with a thick rubber band or some tape or both. This method is not as reliable as a cast cover and is not meant to be a full proof way to keep water out, but it will work for taking a shower or if you are caught out in the rain.
3. Cover with Plastic Wrap
This is the least secure method, but it can do the job in a pinch. Wrap the plastic wrap tightly around the cast in overlapping layers. Make sure the ends above and below the cast are completely sealed. It’s a good idea to use tape to help hold it in place and we strongly recommend that you do not submerge the wrapped cast in water, as this type of wrap is likely to leak.
Alternative Physician Recommended Cast Waterproofing Solution
You can also ask your physician for a waterproof cast in the first place. Waterproof casts combine the traditional fiberglass shell with a waterproof cast padding liner instead of the usual cotton liner. You can wear these waterproof casts in the shower or swimming or out playing sports and they won’t be damaged due to moisture.
