Plasters of Paris are widely used in hospitals and clinics for orthopedic purposes to protect and immobilize a broken limb. When the bandage is exposed to water, a chemical reaction occurs that hardens the plaster.
Our bandage is highly moldable with short water immersion and setting time for our fast-setting XtraGuard product series. Plaster bandages remain the most common method of protecting orthopedic fractures due to the rigid structure and ease of application.
When setting the plaster bandage, use clean tap water in 22°– 25°C (72° – 77° F).
On average, using the proper method of application, it takes 3 to 8 minutes for the plaster to harden depending if the bandage is normal-setting or fast-setting.
Hold the bandage slanted about 45°, and immerse the bandages in the water for 3 to 5 seconds only. Afterwards, using your thumb and forefinger, squeeze the bandage to get rid of most moisture. Note that the plaster will not get lost even if the bandage is squeezed.
In most circumstances, three layers are enough. Avoid creating an overly thick cast.
