Tips for Magnetic Signs

Here are a few tips that will help you with the installation and care of your magnetic signs:

  • Before affixing a 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.
  • Affix to a smooth and flat or gently curved metallic surface.
  • Make sure the entire magnet is flat against the metal surface. Do not place over protrusions (including decals, pin striping, etc.) or concave areas. There should be no air pockets under the magnet.
  • The magnet itself should be at a room temperature (60 degrees F) or above when installed to achieve best results.
  • Exposure to cold weather will make the magnet more brittle, so use caution when handling.
  • If you place the magnet in the wrong position, completely remove the magnet from the surface and re-affix. Lift at sides and not at corners to remove. Do not pull the magnet across the surface.
  • Be aware that long-term use on 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.
  • Magnetic signs will not work on aluminum and plastic surfaces.
  • To guard against moisture and dirt buildup between the magnet and the metal surface (particularly on outdoor applications), remove the magnet at regular intervals. Clean both the magnet and 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 wax to cure before applying magnets.
