Question

I AM IN THE PROCESS OF DEVELOPING SPECS. FOR DRY STRIPPING BRICK PAVER (NOT SURE OF WHAT WE WILL FIND). WHAT ARE THE PARTICULARS THAT WOULD BE INCLUDED IN THE SPECS?


Answer

It seems as if the basic spec would be, Remove all coating from brick pavers. At least, that is the outcome you are looking for.
As to developing a procedure for doing this, which I suspect is your true intent, more needs to be established. For example, what is the coating on the pavers? How does the manufacturer recommend its removal? Is a dry stripping possible? Do we have a penetrating seal here?
Normally, some sort of wire brushing or even sand blasting would provide the abrasive removal of a surface coating, but there are always concerns with dust containment when coating removal is done dry.
