Additionally, the panels were bolted to the sub-surface. “We got some plastic hose and used it as a sleeve to isolate the metal from touching the slate inside the hole,†explained Hawkins. “We used a lag bolt and screwed through the plaster and some framing. It left us with the bolts showing.â€
Little medallions were used to cover the exposed bolts, according to the installer. “We had a machinist come in and make several prototypes before we decided on the one we used,†he said. “The back side [of the panel] was cored out so it would go over the head of the bolt, and then we epoxied it on with a quick two-part epoxy.â€
