A custom back-painted kitchen backsplash is expensive to have made.
There were a few adventurous diy-ers out there who rolled up their sleeves and tried to replicate the sleek look. After all, it looked like it was just a matter of painting the backside of the glass and installing it on the wall.
What I found though is that you have to use the correct glass, paint and adhesive to make the backsplash look like it was done by a pro. Some suggested to use tempered glass to prevent breakage. A lot mentioned buying paint that will bond permanently to glass, and there's a handful of techniques as to how they installed the backsplash in their kitchen.
Here is the shortlist that makes me want to diy it myself and see how it turns out.
