We do all the 3-D signs for this customer, and this particular project was for the entry to their new lodge. We worked closely with the wrought iron designer who did a lot of other work on the project, including the entry. Our task was to produce four 3-by-3-ft. sandblasted single-faced signs and a set of cutout letters.
There were four stone columns at the entry, and we did a sandblasted sign on 15-lb. SignFoam HDU board
for each one. Two of the columns supported a beam structure that went over the entry road, and the letters went on that beam.
Our production approach on sandblasted signs like these is pretty straightforward. This job was on HDU board, so we blasted to the depth we wanted, then blasted through the Grain-Fraim
to create the texture in the background.
We spray the backgrounds with acrylic latex enamel, and finish the raised areas with oil-based enamel, using a brush. We wet sand the raised surfaces then spray the whole sign with PPG Matte automotive clear. These projects go through the shop pretty smoothly, and make very durable graphics for the customer.
