For those who require a slightly softer and more flexible mould making rubber, Craft-Mold 35A is the answer.Craft-Mold 35A is formulated to enable mixing of Part A and Part B on an equal volume of each basis, e.g. 1 part A 1 part B by volume. Usually this type of product requires weighing and can be slow and difficult to calculate.
 

We also have much firmer rubbers 55A and 70A for our concrete moulds and find they have extraordinarily long life and great versatility.  

 Has an amber colour finish

Apply Salease release agent for easy release from all surfaces prior to pouring.
