Welcome to Just Answer, my name is ***** ***** I will do my best to help you with your issue. If my initial response doesn’t answer your question then let me know and we can continue our conversation.

1. rebar should ideally be in the middle of the slab

2. hardener makes the surface harder and is added to the mix before the pour, sealer seals the surface of the slab after the slab cures. One brand is as good as the other there are no real differences in brands except to the salesmen trying to sell it to you
