What is the best way to add the wood grain look to Precision Board?
Since Precision Board HDU does not have a grain structure naturally, it must be simulated into the surface. The grain effect can be accomplished by coating the routed background surface with TSF-45 texture material (made by Coastal Enterprises) and combing the grain in with a hair comb, etc. If carving, a wire brush can be used directly on the Precision Board. When sandblasting, a frame with wires stretched over it can be made and placed over the sign and blasted through. The wires redirect the sand which creates a very realistic grain effect.
