Jesmonite AC100, AC200 & AC300 Retarder From £11.41

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

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

Please note that the end user should perform tests in the workshop environment, as extremes of temperature and humidity can effect set times.

This retarder is suitable for AC100/200/300, but should not be used with the cement based material AC730.
