Concrete foundation is covered with metal flashing, angled away from the house. Flange on flashing is overlapped with tarpaper and lath.
Note the concrete is chipped for a good bond.

Here's how we did it:
Weep holes are drilled in the stop at the bottom. Scratch coat on concrete has a chemical bonder.
Outside corners are defined by nailing up one by four wood strips.
Wood strips for the window returns are aligned with a string line.
Wood strips set. Wall is ready to be filled in.
Wall is filled and rodded off between the strips.
A horizontal screed is set using a string line and a 6 foot rod.
After the wall sets up, the window returns are formed by nailing wood strips square to the window jamb.
Edge cracking is prevented by painting a mixture of flex-con and Portland cement to the join.
Window and door returns are filled in.
Lintels are formed with on by's. Metal lath is nailed on to make sure they don't fall off.
A gap is left around the edge. This makes sure you only see the color coat.
Grooves are made with a wire brush. These look like the grooves cut with a limestone saw.
A view from the top.
The truth is we used the same color for the lintels as the sills. The color was changed on the lintels by splotching with water.
Water table sills are formed using one by lumber.
A gap allows for a 3/4" projection.
Forms are filled and straightened. Note the angle for good water runoff.
Joints in the stones are made using masking tape. When the finish coat starts to set, the tape is pulled off leaving a joint.
Fast forward to the finished wall showing the split faced stones.
Note the gap at the bottom that lets the water out of the wall.
Finish is done by splattering the wall with mortar using a brush.
Mortar is knocked down with a trowel when it starts to set.

Area below the sill is scored to look like block.
Stucco on the bottom of the existing house was scored to look like block.
Our finish should discolor to match this in 117 years..
Finish coat is white portland, lime, and white sand
Color is mixed in a garbage can with our liquid mix of flex con and water.
Here's our formula for the brownstone. It is sherwin-williams "hummingbird" mixed double strength.
The red color is "Foxy", with a lot of black added in.
The black softens the color making the color more earthy, and less pastel..
