The three horizontal seams on the Napoleon Drop Curtain at the Brown Grand Theatre were separating; the thread completely failing, leaving gaping holes in the painted composition. Each needed to be reinforced prior to hanging.
Although this is not a common occurrence, I have encountered it before on historic scenery at Scottish Rite theaters in Milwaukee, Wisconsin, and Pasadena, California.
In each case, the historic scenery was treated at least twice with flame retardants, possibly more. I have noticed that when some historic drops are re-treated with a secondary type of flame retardant, a chemical reaction occurs, causing the fabric to become stained and brittle. Not only will the fabric deteriorate, but the paint will actually begin to flake off. Such is the case with the Napoleon Drop Curtain.
We know for certain that the Napoleon Drop Curtain was treated with a flame retardant as the back clearly states “Flame Proofed”– twice. It is possible that an overly strong solution was applied to begin with, or that a secondary application was added over the years. Some fire marshals will demand that historic scenery be treated ever few years; they have no idea that this will destroy historic scenes.
In regard to the failing seams on the Napoleon Drop Curtain, the only remedy is to reinforce them, thus preventing the further separation of the fabric panels. I reinforced one seam earlier this week as a test sample. This was to make sure that I could manipulate the drop, as well as verifying the strength of the glue and width of the necessary patch. Today I realized that all of the seams were different widths.
There are two factors accelerating the overall deterioration of the painted surface on the Napoleon Drop Curtain: flame retardant and primer. The primary issue is that the pigment has begun to separate from the primer. Saturating areas with an extremely diluted hide glue has helped some. However, I have been hesitant to treat any areas that were not dusting. My hesitation stems from the overall thickness of the combined primer and paint layers. I have actually never encountered such a thick layer of dry pigment paint on an entire drop before, and the added weight to the fabric is quite something.
The weight makes the drop difficult to shift. This drop is incredibly heavy, and it has nothing to do with the actual fabric. The weight comes from the paint. This excess weight is also taking a toll on the fragile fabric. Typically, I am able to easily move a drop once it is on the stage floor. Keep in mind that the drop is on plastic, so it should easily slide in any direction that I want it to go; I just have to get a little air under the drop and it should readily move. The easiest way I can describe this process is playing with a parachute in gym class. Giving a little flip to the edge gets air under the fabric, lifts it up, and helps move the entire drop. When it is airborne, you guide the direction of where the drop will land. Usually, I can do this by myself with very little effort, but not the Napoleon drop curtain. It took two of use today to shift the drop.
The drop curtain was flipped face side down to reinforce the two remaining seams. This was not an easy task. When we flipped the drop face up again, I just about burst into tears. There were entirely new areas of damage to the painted composition. This time the damage was in vertical lines running down one area of the drop. I could not believe my eyes.For the life of me, I could not figure out why there was vertical damage, and not horizontal.
There is that moment of stunned silence when I find myself at a loss. Then my brain goes into overtime, trying to process what has happened and what this means for the rest of the restoration and hanging process. I thought of all of the obstacles that will occur when it is hung from the pipe and raised. I needed to come up with a process to minimize any further damage during handling and hanging.
When I was patching four horizontal tears on the the backside of the drop, I noticed a vertical crease running though an entire fabric panel. At the time, I could not imagine was caused it. This flaw was original to the creation of the drop and not recent. It is now contributing to the paint separation, as are other areas with fabric flaws.
Here is my plan for today:
When the paint restoration is completed it will need to dry overnight. Despite the air conditioning, an abundance of rain this week has not helped lower humidity levels or dry time. Early Monday morning, I will roll the drop onto a tube. Due to limited time and supplies, I am forced to use fabric-wrapped PVC tubes. This in itself is incredibly tricky, as old drops seldom easily roll without creases. The new top batten will already be attached and ready to go. The idea is that the drop will be slowly unrolled as it is lifted; a time-consuming process, as it will need many hands gently unrolling the drop. Once suspended, and the lines leveled (hemp system), the bottom batten will be added. Attaching the bottom batten is pretty straight forward as the original lines are still visible. This is an original batten, by the way. The problem is that I will not be there for the actual hanging, scheduled next Friday.
How the drop responded during handling does not bode well for the overall longevity of this piece.
I was recently asked how long the restored drop could last. Considering the deteriorated fabric and flaking, I explained that it could possibly last for another forty, or even fifty, years. However, at some point it will need a backing piece, one that covers and supports everything. That is always a last resort and should be delayed as long as possible. The repairs to the back will cause a huge problem during the backing process. The added thickness and weight will also become problematic. After seeing the vertical lines today, I don’t know if it will last more than a few decades now, especially when I start factoring in the humidity and heat in Kansas. Temperatures on the stage greatly vary.
I have been restoring historic scenery for quite some time. There are always wildcards that you can’t anticipate, but this one is really unique. For a drop painted in 1978, this should be in much better shape. There is just so much paint on the fabric. The seams will hold, but it is impossible to determine when the actual fabric will give way. I say this, having handled drops three times the age of this one, with absolute confidence that they had several decades left in them.
The thickness of a paint layer ultimately determines the lifetime of a backdrop. The seaming matters too. Over time, I have noticed that vertical seams support the weight of bottom battens better than horizontal seams.
