Fire station in HO

[Graffen]

This is how I did the walls:



I primed them with burnt sienna and then picked some bricks in lighter and darker colors.

Note that they are way to strong in contrast at this stage.





I then lightly Airbrushed some of the base color to tone down the bricks.



To make the mortar, I painted the walls with warm gray oil paint straight from the tube.



I then wiped it off while wet.

I lastly used a towel that was very lightly damped in mineral spirits to remove the oil paint from the brick surfaces.





Just the way I liked it.
