Bricks and Mortar... graduation to the next phase

There are a couple of flaws in the brick work, especially on the original end wall of the building... These are the natural result of floods, minor earthquakes and building owners with sledgehammers banging holes in the house over a period of many years...

On the 'raw brick' side of the wall we have made the old bricks flow, one into the next, with an apparent ease... but this is the side of the wall that was finished with a smooth coat of masonry cement that has cracked and weakened as it has been pushed around.

I interviewed anyone who would still talk to me about mortar patching in this situation... in the olden days we used to use something called "webpatch" (nothing to do with internet security) but I am assured that the product has not existed for at least a decade... it was a great product- high adhesion mortar with fibers added for extra strength- and had a duce of a time finding it's current incarnation.

The Problem:
Create a visually intriguing patch that will add strength to the stressed brick wall and will still be somewhat flexible (in case of new shocks)
First you have to re-create the good stuff... after toting the wheel barrow upstairs into the Lounge, I put together a recipe of 80 pounds of mortar with 1 pound of polyester short fibers and a gallon of acrylicploymer binder/waterproofing (that was the only Thing on the shelves that I could find that had the right chemistry) and mix it carefully...
The stuff ends up very stiff but if you keep slaking it (mixing it back up again) every couple of minutes then it has a long 'open' or working time... BUT! you have to keep slaking it or it all seizes up and that's the end of your work day!

Next it was 'simply' a matter of grabbing a board full of the good stuff and stuffing in the cleaned out cracks and crannies...
This is the cleaned out Crack (or is this a cranny?)... and this is what it looks like with some new goop in it...
Doing the repair work for about 600 square feet of wall took about 5 non-stop hours of rocking good fun! (Then I got to do the rest of it the next day...)
Look! All better! I was just about to float a smooth top coat over everything (old and new) to make a smooth wall like all of the new sheetrock when I actually looked at what was in front of me... I kinda liked it... Now that Victoria is right here it was so easy to call her over and say "Hey, look at this with me for a minute?"

Victoria came upstairs and before I could express an opinion and ask a question blurted out "That looks very cool! Can we leave it like this?"

Obviously, I married the right human! Blessings abound...
