Sandblasted Signs are produced from a very solid, very thick sheet of sign substrate (HDU, Wood). A mixture of air and sand is forced through a ceramic nozzle, stripping away everything in its path. This creates an amazing dimensional signage that leaves a beautiful natural pattern in the wood, and sand textured surfaces in the foam. Then, for the background, lettering and graphics are all painted in contrasting colors, giving the sign a unique high-end appearance.
