Featured Project: Precision Board HDU at Core of New Church Sign


This featured project was sent into Sign & Digital Graphics by Orange, California-based Coastal Enterprises Co., manufacturers of a material called Precision Board Plus, a high-density urethane.

Coastal wanted to draw attention to the versatility and durability of its material so it highlighted a recent project done by a customer of theirs: Signworks Studios in Monroe, Connecticut. Brett Boros of Signworks had been assigned to build a sign for a customer with a limited budget and so, they used PBLT-18 Precision Board HDU, rather than the more expensive sculpted concrete.  

Boros and his team designed a dimensional book out of 18-pound Precision Board to go on the church’s main sign.

“We did the design in Adobe Illustrator and then brought it into Enroute (software, from SAi), did the toolpath and then sent it to our MultiCam 3000 CNC router,” Boros says.

He used the CNC to carve the perimeter shape of the book. The main body of the book was one 2” thick piece of Precision Board. The cover was another piece of ¾”-thick Precision Board. Once the main shape was roughed out by the CNC, he then hand-carved the details in with a dremel and die grinder.

“I use my Multitool a lot from Bosch,” Boros says. “That works good for hogging out material quick.”

Coastal says Boros then used a one-part urethane adhesive to attach the cover to the pages and put a few screws in the back to attach it to the main part of the sign. He then primed and painted it with four or five coats of Benjamin Moore Exterior Aura glaze on the books.

Brett used several different substrates in bringing the entire sign together. The background is Komacel PVC with an aluminum structure framework for it. The post sleeves were also Versatex PVC. The books were Precision Board.
