After the glue was dry on the grass mat, it was time to use the filler to seal all of the remaining exposed foam and blend the roads and river banks into the grass. I use DAP joint compound, but there are dozens of alternatives.
I snuck in two older pics to show the application because I didn't manage any 'action' shots during this build...
Still not much to look at...
Basically, you are just blending the filler into the grass areas. Again, more meandering and erudite description of the process can be found here.
In the past, I wanted my terrain boards to be functional for different scales. For this project I'm not bothered by this and I wanted to add ruts to the road (which would look strange if I was going to use 15mm models with these too). Obviously I could have just drug a brush handle through the the filler, but I worried about the distance between the 'wheels' wavering too much. After I short think on the problem, I came up with this...
Worked like a charm... I know, right? I AM brilliant...
You need to let the filler set for a while before doing this or it will stick to the wheels and you will end up with a mess.
Ok, next up more texture to the earth areas...
