All of the batches I have mixed seem to harden, but what test is there to

If you want to test the hardness of most installed
layups you can use a Barker Coleman (Barcol)
hardness tester. They are not cheap, around $400,
but what is in this game. It needs about 8" of
space above the layup so it can't be used
everywhere.
