What is the water absorption rate that is acceptable in the spec? How do you achieve it with such porous materials like those used in the thin set veneer? It has been my experience that it is difficult to have low water absorption and relative low PSI material as you call out in the ASTM spec mentioned here. It may be considered a secrete formulation but i am curious what additives you are using to get both light weight and lower your water absorption.
