All of our flexible magnets are permanent magnets--remaining magnetized indefinitely, if not subjected to a demagnetizing force. The adhesive found on flexible magnetic materials varies.
We have chosen to provide outdoor grade adhesive on our magnetic strips to ensure its hold on your vertical surface with the added weight of the filled spice tins. Our precut rounds and magetic sheet are indoor grade adhesive. This does not mean these will not be as reliable as the strip. It simply means that, in our testing, the weight of the filled tins was amply supported by the indoor grade and, therefore, the additional cost to our customers was not warranted.
How Strong is Flexible Magnetic Material?
A picture is worth a thousand words!

Sizing Flexible Magnetic Materials:
Whether you choose Magnetic Strip or Magnet Sheet for your magnetic solution, they can easily by cut to meet your size requirements. All you need is a regular pair of scissors.
Applying Flexible Magnetic Materials:
The adhesive back of the magnetic material is pressure-sensitive. To achieve maximum adhesion, 10-20 lbs of pressure must be applied. The 'best way' to apply this pressure is by using a "J" roller.
A "J" Roller is a tool used for putting down laminate. They are available at your local do-it-yourself home improvement store. You may also apply pressure with the heel of your hand or a rolling a soup can. After you have mounted the strip on a vertical surface, such as a pantry door or cabinet door, be sure to let is cure for 24 hours before putting any spice tins on it.
Removing Flexible Magnetic Materials:
If you need to remove the magnetic materials for any reason, it is recommended to use an adhesive solvent, such as Goof-Off to aid in the process. Peel back a small corner from the top of your applied magnetic material. Pour some of the solvent behind it. Begin to gently pull. Add more solvent as necessary. Note: You may remove some of the finished surface of cabinets, walls or doors. Slow removal and solvent will reduce the likelihood of damaging the vertical surface.
