JESMONITE AC730/830/930 Retarder


Setting times for Jesmonite materials can be extended by the addition of Jesmonite Retarder to increase working time.
There is a Jesmonite Retarder for Jesmonite AC100, AC200 and AC300, and a separate Retarder for Jesmonite cement based materials such as Jesmonite AC730 and AC830. Please note that the end user should perform tests in the workshop environment, as extremes of temperature and humidity can affect set times. Further information on Jesmonite Retarder addition rates can be found in the Jesmonite product User Guides.
