Pre-vulcanised liquid latex which is air drying. Makes very economical strong and durable strip-off moulds for the casting of plasters, cements and waxes. Can also be used to cast polyester resins on a limited basis. Moulds are made either by dipping, or by painting on layers of latex (allowing each layer to dry before proceeding to the next layer) onto the original to build to the required thickness. A faster build up of latex when painting can be achieved by using Latex Thickener.
