I see it on every bid/spec project, and paint additives are fairly reasonably priced to achieve a class A E84 rating. What I've never seen before today, and this is at a new firehouse, is a stipulation that the fire retardant stamp/label be visible on the backboard. I've never had to label a backboard as such. I searched, but could not find a roll of labels for this purpose, and I would think one would have to show some type of certification to even have possession of these. Any thoughts?
btw, I chuckled because the whole spec read that the fire retardant backboard be painted to match the surrounding walls, but the label had to be masked off so it remained visible. I immediately contacted the department of redundancy department.
