|Here are photos of our front
wall "restoration" from September-October 2010. The wall
has a brick core stuccoed and scored to look like randomly coursed
stone. It is exposed on all sides and years of rain had done a
number on it. I chipped off the loose stucco and then patched with

Chipping off the "loose" mortar was a delicate task as I could've pried it all off if I really tried. I settled for leaving mortar that was "well attached."
I used a regular mortar mix for my stucco as I believe was done originally. I did not use a hard mortar, as I wanted it to have a little flex since it's a fairly large span.
I applied the mortar in two fairly thick layers to reach the existing surface. I matched the "mortar joints" as closely as I could as the mortar quickly set up. With the excess mortar, I built a small buttress at the base of the wall to shed water away from the wall a bit.
After the mortar mix had cured for three weeks, I applied two coats of Zinsser WaterTite. I had good success with Zinsser in my basement.
After letting the Zinsser cure for ten days, I applied a oil-based primer coat. After the primer coat, I applied two coats of Miller oil-based porch enamel. It's a semi-gloss but is actually quite glossy. Good for repelling water and providing a durable finish.
The wall weathered a wet winter nicely. The stucco work and paint job seem to have kept water out of the wall. This spring, I will paint the grout lines a shade darker than the body to make them pop just a little bit.
I also scraped, primed and painted our original light fixture and reinstalled on the corner. Here's a shot of the finished wall with the house for some context. The wall is in the lower right quadrant.
