Product Description

GemLeaze DC is a low-odour concrete mould release agent developed for dry-cast and precast production. Applied as a thin, even film, it helps prevent concrete from adhering to the mould and supports clean removal after production.

It is primarily intended for steel moulds used in repetitive production, including hollow-core flooring, manhole covers and other precast concrete components. It may also be used on compatible timber and ABS plastic moulds, subject to a trial application.

The formulation is designed to support consistent release and surface finish while helping protect steel mould surfaces during normal use. Excess product, runs and pooling should be avoided, as overapplication can affect release performance and the appearance of the finished concrete.
