Soak one roll bandage together with its spool obliquely tilting 45 degree into tepid clean water (approx.25℃) about 5 seconds, until bubbles stop rising in water.
Take the bandage gently out of the water, and squeeze out the excess water with hands pressing the bandage softly from both edges towards the middle.
Wrap the bandage layer upon immediately after squeezing, and do not wrap the bandage too tightly.
The normal setting time is 2-5 minutes, but it can be changed slightly in the following way; To accelerate the bandage setting, comparatively warm water may be used, or if necessary, a hair dryer may also be applied. The setting time may be retarded approx. 4 minutes by adding 2 mg sodium sulfite (anhydrous) per 1000 ml water before soaking.
