Paint it white.

Back with the £d printed engine shed, I have applied some white primer to the inside of the engine shed itself and to both sides of the rook as well as to the doors and window frames. The white on the inside of the engine shed will remain but be dirtied to replicate how many such buildings where painted in this colour to increase the light levels. The roof will be rusted up and the other parts will probably end up a red to match some other railway infrastructure on my 009 layout Chalkdon.

With the primer dry I have masked off the inside of the shed ready to put a stone colour on the outside but that will have to await until tomorrow - but it won't be painted white!
