Set times of all Jesmonite composite materials can be extended by the addition of Retarder to increase working time.

This Retarder is for AC100, AC200 and AC300. Please note that the end user should perform tests in the workshop environment, as extremes of temperature and humidity can effect set times.

Typical inclusion rates are 2g – 8g per kilo of mix.

Extends ~30 minutes of pot life.
