You dumped a two to one hardner into a 5 to one hardner - correct?

I've mixed two to ones but not what you did. The only thing you can do is some test batches to see how it works. Many times they will kick but the final hardness will be compromised. If you put too much hardner in a two to one mix, it hardens kind of rubbery and not rock hard. So it's anyone's guess. I like experimenting. Give it a try. But give it several days to make sure whatever youÊdo hardens to a sandable hardness.
