Could you fellow modellers please give me ideas? I have made some hardwood bases with routed edge and varnished they several times. What is the best way to then apply scenic base on top ?????? I have tried putting a layer of plaster of paris onto the wood and then sand/pva glue watered.

I use plaster with a little PVA mixed in. I build up the terrain gluing styrofoam cut from packing or insulation to the base and then apply the plaster over it. I've never had any problem with cracking or shrinking.

Thanks Pat will give it a go cheers
