These are the prep instructions for the stuff I applied:

There are some good tips in there that are applicable to all concrete prep.
Use the muratic acid! Dilute 2 or 3 parts water to 1 acid. Their suggestion
of using a flower sprinkler works great! I did the ammonia neutralizer like
they specify. Used shop vac to pick up all acis and ammonia, then went back
over it with plain water & vac'ed up about 3 times. The cement should be
fairly rough - approx like 100 grit sandpaper.
