How to use setting type joint compound?

Setting type joint compounds come in powder form and are mixed with water immediately before use. This type contains plaster of paris and sets through a chemical hardening process rather than evaporation, which gives it an advantage in filling holes and gaps that would take many days to dry out and have shrinkage cracks using the drying compound. Setting type compounds are available in setting times ranging from 5 to 210 minutes and types that bond extremely well and are very hard and types that are soft and easy to sand. Once mixed with water, the setting type must be used before it sets; any leftover is wasted and if not enough is mixed, another batch is needed to finish the job, and all tools must be very clean or the compound may set up prematurely. This makes the setting type compounds harder and more time consuming to prepare, but they set quickly. Setting type compounds can be used at temperatures down to 45 °F (7 °C). Some drywall professionals use setting type mud for the first coat and a drying type for the thinner finish coat. Setting type compounds do not soften when they get wet, thus are better for moist environments, such as bathrooms.
