Mold release 100% required for Epoxy Resins or you will stick the cast in the mold.
For use with Makers Select HDPE Molds - makes for easy de-molding
First time use demolding tip: If the blanks don't come out easily with air or a tap try whacking the mold upside down on the table. This creates some air behind the blanks and they should pop out more easily.

How to calculate volume
How to determine resin needed for a rectangle or square mold (this is a good place to start, you should verify during pour and make adjustments in future) There is .554oz in 1 cubic inch of resin
liquid volume = ( length x width x height ) x .554
example- if your mold is 6" x 5.5" x 1" = 33 cubic inches take 33 cubic inches x .554 ox per cubic inch = 18.28 oz
