Can I prime and paint my Precision Board sign panel prior to sandblasting?
Yes. Priming makes it easier for the sandblast resist to adhere to the surface of Precision Board. Leaving the mask in place after blasting and using it as a paint mask during priming and painting of the blasted area also saves time. Important: Always roll out the primer and paint evenly as overlapped areas will result in uneven blasting. Be sure to use the proper sandblast stencil for primed HDU.
