How to restore character to apartments with ancient, painted-in wiring
In short: In old New York apartments, you often find a mess of coaxial cables and old wires installed by Thomas Edison and Company. Rather than a full gut renovation, you can restore the walls by carefully removing these relics and repairing the inevitable gouges and damage left behind.
When dealing with historic buildings, you will often encounter old wiring—sometimes even coaxial cables—that has been painted over for decades. Removing these can leave significant damage to the walls, including gouges and sharp staples. To achieve a professional finish without a complete gut renovation, the goal is to create consistency rather than absolute perfection.
The repair process begins with cleaning the area and removing old paint. Once the surface is clear, a sealer like BIN primer is essential to provide a solid base for patching compounds. This primer is highly efficient, drying in as little as 10 minutes. This step ensures that the subsequent plaster or joint compound has something solid to adhere to.
For heavy damage, a custom compound mixture can be used, such as mixing joint compound with a little plaster. When repairing deep gouges, a technique involves creating a new 45-degree angle to smooth out the surface. After the compound has set, a light skim coat can be applied to further level the area.
The final stage involves sanding the edges to create a smooth curve and wiping away all dust. A thick, even coat of water-based primer is then applied to seal the repairs. It is vital to apply the primer carefully; sloppy priming leads to sloppy paint. Once the primer is dry—often in less than an hour—the surface is ready for the final paint job.
