When the filler had dried, I created a dark sand brown wash, shading the entire floor and crevasses of set.
While that was drying I turned my attention to the pipes. Painting the parts with Games Workshops Retributor Armour, then dry brushed with Necron Compound. After this had dried both parts where glued onto the pieces.
I added filler mix into the crevasses between the pipes and the wall. Dry brushing the mixture over the pipes to weather them.
Using the sand brown mix that was originally made and added to the filler, I have painted the border and dry brushed the floor with. Once the filler around the pipes is dried then I'll dry brush the wall.
