I love the smell of Prometheum in the morning

Before you can paint MDF you have to seal it. Now, I have some dedicated MDF sealer purchased from TTCombat which is absolutely amazing – If you’re painting a small building. As it comes in small bottles and is also a brush on medium I looked at the Promethium rig and decided there were better uses of my time. So I experimented and I used a few cans of cheapo spray varnish purchased from my local DIY shop (can’t even remember the name or brand now). I sprayed the entire model, probably twice in some places just to be sure (because you can’t actually tell once the varnish has dried). I then primed all the walls using Zandri Dust, all the metal using Army Painter Gun Metal any flat surfaces on the platform with Mechanicus Standard Grey and the chimney stacks were primed using Army Painter Chaotic red. Using the varnish as a primer worked a treat. To add a bit of texture I coated the legs of the structure in PVA and sprinkled some fine sand on before priming. However before I finished all the drybrushing I realised something about the entire piece that would require additional work so I stopped painting. The first issue was structural integrity – it was really flimsy. Second was the gaps in the joints of the wall sections – par for the course with MDF builds.
Because the chimney stacks aren’t fixed, I decided to finish them before doing any rework. To complete the chimney stacks I gave the edges (they’re octagonal) a drybrush with Mournfang Brown and then a lighter drybrush of leadbelcher to give them a worn, used look. Then around the vents at the top I used some black weathering pigment to create a sooty look, I also used this extensively on the inside of the chimneys. Then, to disguise the joints around the top, I painted them a bright red to look like altitude warning lights commonly seen on tall buildings.
