Weathered Asphalt Street is Easy to Use Now you can add a street in need of repair to your layout quickly and easily. This self-adhesive street roll is decorated to simulate a cobblestone street that has been paved over with asphalt, and then allowed to deteriorate. The street surface is a very thin layer of foam with a self-stick backing simply peel off the backing and stick the sheet to a clean, smooth, non-porous surface (if applying to base scenery materials such as plaster, make sure to seal them with paint before applying the street). The street is very flexible and can be bent to add curves and grades. It′s easily cut to fit with a sharp hobby knife or scissors.
