Put into a 'Duel' painting competition at my local
FLGS.
3 layers 3mm particle board.
Bottom base
Middle for the models
Top is bottom corner for a side walk.
The cuts are separations in pavement corresponding to the models bases.
Holes wer cut with a box cutter whilst the pieces were still seperate.
Dry fit the models
Added sand for rubble and fixed some holes.
Sand has mix PVA glue and water very thin to fix it in place for all time.
Undercoat cheap gloss spray (include the underside so doesn't warp the board). The board soaks up alot of moisture so you can need a lot of spray.
Painted as per road, rubble and sidewalk to match the models and my MCP basing.
Models added (terrain is blu-taced in place.
