Before we speed the drying time of a poultice, we should first consider whether it would be advisable to do so. You should only speed up the drying time on a poultice if the poultice has stayed wet for at least 12 hours. If the drying time is too rapid there may not be adequate time for the chemicals to react and the stain to lift from the stone or other surface.
Some poultice products come with a drying accelerator, which is added to the poultice to speed up the drying time. However, these products may have cause discoloration or damage if they react chemically with the surface. Always check the label to be sure what you are using is safe for the surface your are poulticing.
