Is magnetic wallpaper a bad product?
Well, the supplier only promises on the website that you can hang paper and fabric on the board (with the 4 kg magnets)... And that it's super smart wallpaper with a magnetic effect.
What's criticizable is the advice he received from the company that sells magnetic wallpaper.
The fact is, if the magnetic wallpaper was to be as magnetic as the customer expected, it would be nearly impossible to set up because the saturation of the wallpaper with magnetic chips would require so much processing (painting) of the wallpaper, that it would become really heavy and difficult to install (and have a thickness of something like 3-4 mm).
Of course, there is also the possibility that we are completely wrong in our calculations (!), but it's hard to argue that it's a strongly magnetic board when the magnetic wallpaper cannot hold up a magnet with a carrying capacity of 1.5 kg. Even a magnetic board painted with magnetic paint with 1 layer, where otherwise at least 3 layers are required, will be able to carry a magnet with a carrying capacity of 1.5 kg...
Our last reply to the customer was therefore as follows:
"Thanks for the link!
I've just closely studied it. They don't write the sizes of the magnets, so I've found the size ratio in relation to the things that are hung up, and it looks like 10x10 mm neodymium magnets - if they are of good quality, they can carry almost 4 kg (otherwise a bit less). And the text states that you can hang up paper or fabric, i.e., small light things. So it's really poor quality - just as difficult to use in daily life as a glass board. And bad advice from their side.
Spend a few days thinking about what the purpose of the board should be. Because you will experience that the magnets, due to the weak magnetism in the wallpaper, will be attracted to each other and clump together if placed too close.
I would consider painting over the wallpaper with magnetic paint/board lacquer + contact those who advised you, and ask for a refund for the product. That's what I would give if I had sold such a product as "a strong magnetic board".
A fun way to test the strength of the magnets: first check the strength (just by using them) on the magnetic wallpaper. Then test it on the refrigerator, the radiator, or another magnetic surface... and feel the difference."
What's Next?
The customer will stop by in a couple of days, and then we will find a solution together here at the office, where he can test different magnets and learn a bit more about magnetic paint.
And it's hard not to cringe at how little pride people have in their work because it's really hard to explain away SUCH poor advice about a product.
Above, you can finde magnets between 5-8 kg. This is the strength we tested with the best results. And afterwards, the same customer returned to us and bought magnetic paint for his wall to make it more magnetic.
