Sandblasted & routed signs create a sense of permanence & quality. Due to environmental concerns, we only use high quality, high density urethane. Sandblasted signs can either have a wood grain background finish that is virtually indistinguishable from the traditional redwood, or a pebbled finish that closely resembles a cast metal plaque. The urethane is a much more stable material than redwood, that won't rot, split, or warp. Finished with the highest quality paints available; to ensure a beautiful sign that will be maintenance free for years.
