How to Apply & Care for Flexible Magnets

Please read and follow instructions to care for your flexible magnets.

Important -General Caution

 Applying any material to a painted metallic surface without following all use and care instructions may result in damage to that surface. By following these instructions, a product user can ensure top performance. Failure to follow these instructions and tips may cause damage to the magnetic material and/or surface to which applied. The   Magnet Store will not be held liable for any damage caused by abuse, misuse or failure to follow the enclosed tips and instructions.

Storing Flexible Magnets

When not using the flexible magnetic sheet, keep them in a clean, dry place. Store rolled stock on end to keep it from developing flat spots. Store rolled sign material with the printed or vinyl side out. Stack flat magnets on a level surface. Avoid placing objects (such as cartons) on top that could damage the face; do not stack with magnetic sides facing each other.

Preparing Magnetic Surfaces

Before affixing any magnetic sheet to a metal surface, be sure all surface paints; clear coats and waxes are cured (hardened). Clean the metallic surface and the magnet with mild detergent. Wipe with a soft cloth or allow to dry. (Approximate curing times: paint—90 days; clear coat—60 days; wax—2 days)

Applying Flexible Magnets

Before applying, test all inks and paints used on the magnet for adhesion and solvent compatibility. If possible, affix to smooth, flat or gently curved metallic surfaces.

Make sure the entire magnet is flat against the metal surface (i.e., no air pockets). If you place the magnet in the wrong position, completely remove the magnet from the surface and re-affix. Do not pull the magnet across the surface, or it may stretch due to the resistance caused by the high magnetic strength.

 Avoid use on horizontal metal surfaces exposed to direct sunlight (such as automobile hoods/windows), temperatures exceeding 71°C or temperatures below -26°C. Exposure to cold weather will make the magnet more brittle, so use caution when handling.


Be aware that the long-term use of surfaces frequently exposed to sunlight (such as vehicles) can result in uneven fading of the surface because the magnet-covered area is shielded from ultraviolet rays. Avoid use of non-metallic body fillers, simulated wood grain siding, and repainted surfaces.

Cleaning Flexible Magnets

To guard against moisture and dirt build-up between the magnet and the metal surface (particularly on outdoor applications), remove the magnet at regular intervals. Clean both the magnet and the metal surface with mild detergent; wipe with a soft cloth or allow to air-dry. (For vehicle-mounted signs, remove and clean DAILY.) After waxing and polishing, allow 2 days for the wax to cure before applying magnets.
