How to repair neon signs?

Neon signs can be repaired in different ways. It all depends on what has gone wrong with the sign. Neon tubes are usually damaged when they explode, which causes glass shards to fly around and break other parts of the Neon Direct tube or even neighboring tubes.

Here are a few steps to follow when repairing a neon sign:

1. Healing Broken Neon Tubes with Heat

In order to repair a shattered neon tube, you will need metal shears and a heat gun. First of all, make sure you wear protective goggles when handling hot glass. No matter how careful you are, broken glass can still fly around when you cut it.

When cutting the glass, remember that tubes come in different shapes and sizes. Some of them will be straight and narrow, while others will look more like a spiral. For the last type of tubes, you do not need to cut them in half, but rather curve the glass so that it looks like an S shape.

2. Attaching Neon Tubes with Epoxy

If there are no broken tubes, but you just need to straighten out your artwork, you may use epoxy.

However, there is a special type of epoxy that does not emit an odor and is less toxic than the one we usually purchase from stores. If this rare type of epoxy can’t be found, do not try to substitute it with common epoxy.

3. Painting Broken Neon Tubes or Glass

If you need to repair broken neon tubes, you can also apply paint to fix them. For the best results, use enamel paint because this type of spray resists high temperatures and is highly durable. Paint should be applied to the cold glass so that no heat is emitted.
