Natural Rubber Latex is a fantastic product that is tougher than just about any other mould making rubber you can buy. It is almost hazard free and very simple to use.
The choice of the present day garden ornament mould maker or a professional mould maker of days gone by for almost any application, cost and toughness is its biggest advantage over the competition products like RTV Silicone or Hot Melt Systems. However being up to 40% liquid and an air cure system, it will shrink, dimensional stability is questionable and the time to make a mould is long, since you must wait between coats for the product to dry.
