Eazymix Extratime Plaster Retarder Mix Sachet Slows Setting Times Of Plaster

Extra-time is a chemical additive for use with finishing plasters. The additive slows the curing process of the plaster by slowing the chemical crystal formation that causes the gypsum plaster to set or harden. Extra-time is recommended for moderate lengthening of finishing plaster setting times. Extra-time will lengthen the setting time by 30-60 minutes depending on the ambient temperature and relative humidity of the environment.
