How to do Acid-Etch stained concrete?

Sorry don't understand the question. Are you prepairing to acid-etch the concrete to stain it or to remove a stain, or is it something else?

I tend to acid-etch concrete to stain it, precisely putting different art works on concrete. I want to know necessary procedures, equipments to achieve this or rather websites to visit.

Thanks

Thank you. I find it helpful.

There are many resellers that teach courses. One local hands-on course here in Montreal is a two day class for $250ish and you get exposure to a lot of different techniques.
