@Marty Henry. Is that a particular brand you are talking about? From what I have seen Floc is just Aluminium sulphate, not Alum (no potassium or ammonia).
I think I will give it a try though as it is cheap.

Bit late as others have answered but post brands I have seen or used are pot alum. Aluminum sulphate would also work, its more acidic and will coagulate the proteins in the hide pretty well, but as with alum the final cured hide is not waterproof.

Thanks @Marty Henry, that is what I needed to know. I can get Floc (aluminium sulphate) from Bunnings for under $10/kg compared to $50/kg for Aulm and I don't plan on getting the skin wet.
Thanks everyone for the help.
