Jesmonite Thixotrope can be added to AC100, AC200 and AC300 compounds to adjust the thickness of the mixture using this liquid. This is particularly useful when applying the first layer into the mould, which can be a little thicker (approx. 1-3 mm) while still not sliding down the sides. Thixotrope can also be turned into a paste, which can be used as a repair filler for the mould.
