Good point; read the can to see if impermeable or not... would high-pressure water remove grout?

It don't think it can remove anything that isn't loose. Mortar joints should be safe. ( Cmu is set with mortar, filled with grout. I often find myself saying mortar when I mean grout, and vice versa. They are similar.)

Here's a photo of cmu being water blasted. My first thought was light sandblasting, which is also an option.

You know I had a painter recommend that to get it off but wouldn't that just saturate the walls so badly?

In my county you have to put a ripper of drywall at the top plate for a firestop and fire caulking, the same goes for sofits that die into wall,

The wall will dry. Keep the goal of all this in mind--a wall that can dry. More importantly, once the siding is up, a wall that doesn't have nearly as much need for it.

Makes sense... when I get to that point I guess I'll give it a shot and see if it comes off easily. If so, it's another might as well to do it right.
