Need to extend the working time of your Jesmonite materials? The setting times of all Jesmonite composite materials can be extended by adding a retarder. There is a retarder for AC100 and AC300 materials, and a separate retarder for AC730 cement-based materials. Please note that the end user should test in the workshop environment, as extreme temperatures and humidity can affect set times. Addition rates can be found in the user guides for the various composites.
