Mixing black paint into the joint compound, and the black wash, are both good ideas. If I remember correctly, this was your first structure build? If so, it's even more remarkable that it looks so great.
I do almost all my weathering with chalks. Years ago, I bought a basic set of pastel chalks* from the art department at my local Walmart for $3. I'm still using that set, along with a set of gray & black chalks, and a set of earth tones that I bought from Micro-Mark.
I first airbrush the red brick color on and let it dry overnight.
For mortar lines I just drag a stick of chalk across the pre-painted brick surface. Then I wipe the brick faces clean with a dry paper towel. I do sometimes use a black wash, but it will usually remove any chalk it encounters, so I may need to do the chalk over, after a wash.
Much more often I skip the wash, or any other liquid weathering material. Instead I "paint" with chalk. This process is exactly the same as painting with that "old school" set of children's water colors, in a long black tin box, that you may have had as a kid.
I wet a small artist's paint brush in water, and stroke it along a stick of chalk. Then I paint the chalk onto the model. At first, not much color shows. As the chalk dries, the color appears. With practice you can do all sorts of effects with chalk. By the way, you may have read about modelers "sealing" weathering chalks with Dulcote. I don't do this, since the Dulcote erases nearly all the chalk effects. I find that the chalk stays on just fine without any "sealing",even on models that get handled, like freight cars.
Any mistakes I make can be erased with water. I just rub a wet towel over the part I want to erase.
A brick building, especially an old one, seldom has every single mortar line showing the same color, or sometimes at all. Weather, airborne dirt & dust, and time, tend to dull and /or change the color, and prominence, of mortar lines. If you look again at my N-scale model of Seattle Union Station , you'll see some areas where the mortar doesn't show much at all, and others where it's fairly clean white. Also some mortar usually gets on the faces of some bricks, and sometimes used bricks are recycled into a new structure. The lower left corner of the single storey mezzanine part of the station shows this effect.
Below are some more photos of the station. It's all scratchbuilt, except for the two longer exterior walls. They are kitbashed from two different DPM kits. This is the centerpiece model for my layout, so I went a little crazy on it.
* If you decide to try weathering with chalks, be sure to get "PASTEL CHALKS", not plain "pastels." The latter "pastels" are like crayons, and not at all suitable for weathering.
