Hanging up a painter's sheet

A while ago I had to repaint my ceiling in the kitchen. Since the walls have been painted just recently, I had to protect them from paint splatter. I tried to attach the plastic cover to the wall with tape, but I was unsuccessful. The tape kept peeling off the wall and fell to the floor.

Then I remembered that my flat is a new construction and walls are reinforced with iron ledges. I used 3 disc magnets from my last order and searched the walls until i found the iron ledges. Then I could easily hang up the plastic cover with the magnets.

The painting took its course and when I took off the cover there was not one paint drop on the walls!

Note from the supermagnete team: A customer took advantage of the same concept with his project Post-it wall.
