This board is double sided; brown one side and grey on the other, so I can do urban or wasteland set-ups easily.
Each side probably had around an hour painting time at most, and the advantage of the cork is it provides some texture. I painted it by first splodging paint on and using a roller, adding a lighter colour onto a darker colour and rolling that in. The brown side then had some more colour sponged on (using very cheap household sponges).
Expect to see the boards getting some use soon enough.
Painting time: maybe a couple of hours all-in, over around 4 sessions.
Cost: around £12 to £14 for effectively 'two' boards (although only one can be used at a time of course!)
