I wanted something more with our storage wall (from Ikea) in the living room. Since we have some concrete details in the house I preferred to go back to it but did not know to mold own discs. Also, I wanted to have a more slim look.
Then I and think of the thin cement discs (Minerit) we had used on the outside of the dormer windows when we built on the hayloft studio. They were both thin and water repellent.
Said and done, we bought home a couple of slices and mounted, and here is the result!
Wish you a nice Friday!
