How long does it take for the plaster bandages to dry?
With plaster bandages there is a difference between set time and dry time. Set time is about 3-6 mins with plaster. The set time is the time it takes for it to become rigid enough that it does not move, this is the point at which you can knock on it when it sets. The dry time will actually take about 24-36 hours depending on the humidity of your location. The plaster will still feel damp for a few days. All plaster no matter the brand or type takes the same amount of time to dry and set. The padding underneath a cast, even if it is fiberglass, will still take 24-48 hrs to completely dry.
