The best tips for removing enamel

To re-enamels an object, the old material must first be removed. Enamel is very hard, but splinters relatively easily. It can be removed in various ways without causing any damage to the ground. Read here how it works best, from sandblasting to sanding to chiseling. Important here is and remains the necessary instinct.

Remove enamel with the blasting unit

A relatively simple way to remove enamel, the sandblaster offers. Since enamel is extremely hard, you need corundum as a blasting medium. This material is also suitable for rust removal of metal and for deburring.

Even colors can be removed with corundum from metal, leaving behind a matte surface that can be easily further processed, for example, to re-enamels.

Chisel enamel from the surface

The enamel coating of an old bathtub can also be chiseled using a hammer and chisel. The metal tray is likely to take more damage from this procedure than blasting or grinding.

The advantage: The chipped enamel can then be reused by applying it to a hot surface and melting it smoothly.

In this way, you can make your own jewelry or create other DIY products made of enamel. For professional enamelling, however, you need an absolutely rust-free surface, which was best treated beforehand with hydrochloric acid.

Remove enamel by abrading

Especially when it comes to liberating smaller areas of enamel, also the grinding is recommended. Use a steel brush that you place on your drill.

For round zones you use a conical grinding head, with which you can work very precisely in this case. Large-area sanding, of course, happens with the largest possible sanding attachment.

Tips & Tricks
