Etching 101 – Sanding & Masking

After carefully removing the guts (provided the etching is on an enclosure from an existing build), remove all the original decals & paint with 80 grit, coarse sandpaper. Even if you’re starting with a bare enclosure, it’s good practice to sand away any residue left from the manufacturing process this way. Wet-sanding (keeping both the enclosure and sandpaper wet at all times) will make quick work of any paint job.

You’ll find that the enclosure quickly becomes “muddy” as you wet-sand. Just dunk it and the sanding block in a bucket of water to rinse them, and continue removing paint.

When most of the surface is done- and don’t overlook the corners and edges!- take the sanding up by hand to get the patches that were missed by the sanding block.

Make sure to get every little crevice

After about 10-15 minutes of work, the enclosure will start to look pretty good:

  • Howard,
    I use Adobe Photoshop to create the final images for print. Good luck, and if you have any more questions along the way, post ‘em.

  • Your process is very similar to PCB manufacture. I will certainly be trying it out instead of using a commercial silk screen process.

    Many thanks for a first rate tutorial.
