The key is to clean as you go with sponge and water. Then you just have a little grey film to wash of with acid. I did not do the wet lay, but heard enough marching orders to the crew, a lot of venting when it was not done, and have done my share of muriatic acid washing.
I can't remember the name of the primer they would use, it was C- some number or other. It was remarkably similar to elmer's glue in look and smell. They also bought dark mortar when they wanted dark mortar rather than adding tint themselves. It is quite available here, I expect that it is everywhere.
They'd lay bluestone on about an inch of mud. They'd join it severa days later.
