Evacuator pressure question

Fabulous FX

I am casting a plate mold with Smooth On:  Smooth Cast 300 (Urethane Resin).  I was wondering what pressure I should use in my evacuator while it's curing?

Hi Fabulous FX,

For Smooth-Cast 300 you should use 60 PSI (4.2 kg/cm2) air pressure for the full cure time of the material.
