Concrete Slurry for Exterior Brick

I saw some posts about slurry treatments for exterior brick but I have a couple of questions. I have seen a textured finish on brick that looks like a thinned out concrete. Is this the same thing? I like the aged look and the fact that is can cover some less than desirable brick and I am trying to replicate it. What is it made of, how is it applied (sprayed on?) and can it be colored? Does it last a long time? Any info would be appreciated! Thanks!

When we coat brick, we use 2 parts white portland to one part type s lime in enough water to make a very thin batter consistency. You must experiment to get the proper consistency, since different brick take the slurry differently, and you will have to match your expectations of the amount of residue you want on the brick.

To slurry an existing wall, you will not want to spray it, since that will also coat the joints. You will have to coat each brick face separately. It is very durable and lasting.
