I've finally finished laying the plastic brick sheets. Once laid, I sprayed all with Rustoleum Red Primer, my typical go to for a brick color. I then use pieces of styrene to simulate concrete paving and paint those Rustoleum Gray Primer.
Once all was done, I used filler tinted with grey paint to add mortar to the bricks. Once dry, I used various washes to darken the bricks and act as weathering.
Next up will be making sidewalks which will be built up from styrene.
