I bought some terrain for Warhammer 40K a few years ago, but never bothered to make it usable on the tabletop until recently, because I had No Mans Land on my doorstep: if I wanted a game I had access to the gaming tables and their vast array of terrain.
Unfortunately, NML is no more, but now that I've moved house I now have a dining room (with a big dining table) to play games on, so in advance of a four-way game a couple of weeks ago, I decided to refresh my modular gaming boards (which I'll blog about soon) and paint the terrain pieces that I'd assembled all those years ago.
The paint scheme is very simple: after a black undercoat, the walls were drybrushed with Tin Bitz and then Army Painter, Gunmetal, then washed with Army Painter Strong Tone wash shot through my airbrush. Then I applied some Forge World Light Earth weathering powder at the base of the walls. The plasticard bases were covered in PVA glue and acquarium sand, then sprayed with Army Painter Leather and then drybrushed.
