After the STANDARD SET has cured beyond the tacky stage, apply the plaster bandages to create the support shell for the front half of the mold. When applying the plaster bandages, be sure NOT to cover the breathing holes for the model. (In the application shown below, the model is breathing through his nose.)
After the plaster bandages have been completely applied, it is necessary to let the bandages cure solid. This will usually take about 7 - 10 minutes.
