I filled the edges of the cobbled worn sections with Deluxe Materials plastic putty:
I did a couple of coats sanding in between. I put a coat of artist’s acrylic varnish over the top.
I tried a couple of surfaces for my dock based on Gordon Gravett’s Grasslands book which also includes roads.
Basically, you paint a gloss enamel and sprinkle either ash or chinchilla dust on the surface. I had already bought some silicon carbide grit in 80, 220 and 400.
I didn’t want to use enamels as I had bought a couple of Lifecolour acrylic tarmac colours – middle eastern and European. To stop it drying too quickly I bought some slow drying medium to allow longer for the grit to settle.
First I tried the chinchilla dust:
It’s a bit gritty for my liking so I tried the silicon carbide 220 grit:
I ran out of the 100g bag so I tried the 400 grit – really a fine powder:
I’m waiting for them to dry and will hoover them off (whilst trying to keep the spare powder – easier said than done I guess.
