Sculpted Concrete Stone and Precision Board Plaque

Coastal Enterprises, manufacturers of Precision Board HDU, is proud to host guest blogs written by some of the signage industry’s biggest movers and shakers, posted to the Precision Board Blog.  This guest blog is written by Jim Dawson with Synergy Sign & Graphics, based in Strasburg, Ohio.  Jim shows us how he created a memorial plaque out of steel, concrete and Precision Board that looks so much like one piece that you can’t tell where the rock ends and the urethane foam begins!  Read on to see how he crafted this masterpiece of mixed media!

In Jim’s own words…

In the fall of 2019, I was contacted by Kent State University Tuscarawas to come up with a memorial plaque to be placed near their walking path on the campus. They wanted to honor John Demuth for his service to the campus. They also mentioned they liked one of our previous sculptures that was produced for the owners of a local Harley Davidson dealership.

With that in mind, we developed a design that would use the same basic construction for the stone and embedded plaque. Once the proofs were submitted and approved, we started construction. The base plate and ribs that make up the framework were cut on our Multicam V-Series Plasma. We then assembled them using our Miller 212 Autoset Mig Welder. The framework was then wrapped in 1/4” pencil rod to frame out all of the stone geometry.

The plaque was programmed in Enroute Pro 6 software and then sent to our Multicam 3000 series router. The X-Edge XV2006 60º V groove bit handled all of the carving into the 2” thick PBLT-30 Precision Board HDU. The plaque was then mounted to the steel plate using PB Bond 240 urethane adhesive and stainless steel screws.

With the framework and plaque mounting complete, it was time to wrap the frame with galvanized metal lath in preparation for application of the fiberglass reinforced concrete.

Concrete application was next. We troweled on our special mix of fiberglass reinforced concrete and the waiting game began. Wait time was roughly 3 hours before we began to carve. As you can see from the pic, we leave the application very rough on purpose. It’s not until the carving stage that the details really start to show.

Once carving is complete, we allow the piece to dry for several days. It all depends on temperature and humidity.

We then paint the piece with three coats of exterior grade latex paint and allow it to completely dry between each coat. Once the base coats are dry, we apple a series of glazes that deposit colors into the cracks and pits in the piece. This step is when the pieces truly come alive.

Once special thing we did on this piece was add sand to the paint to blend the area where the plaque is. It worked beautifully!
