Installing Magnetic Media: Do’s and Don’ts for Flawless Results

But even though magnetic graphics are installer-friendly, there are still a few critical guidelines to follow to get the best results with printable magnetic substrates. A poorly installed magnetic sign can lead to curling edges, poor adhesion, or even loss of the graphic in high-traffic or mobile environments.

Here’s your go-to guide for magnetic media installation — covering what to do (and what to avoid) for smooth, secure, and professional-looking installs.

Do: Use a Clean, Flat, Ferrous Surface

Magnetic graphics will only adhere properly to ferrous surfaces — meaning surfaces with iron or steel content. Aluminum, plastic, or wood won’t hold magnets unless a magnetic-receptive base layer is applied.

• Clean the surface with isopropyl alcohol or a mild detergent to remove dust, oil, or residue

• Ensure the surface is flat and smooth to avoid air gaps or lifting

• Test with a small piece first to check magnetic strength before applying large graphics

Don’t: Install on Dirty, Wet, or Curved Surfaces

Contamination or uneven surfaces will reduce magnetic hold and may cause the graphic to fall off or curl.

Avoid installing on:

• Vehicles or fixtures with moisture, wax, or dirt

• Rounded or highly contoured areas without enough surface contact

• Surfaces that get very hot, cold, or damp — unless the media is rated for it

Do: Apply from Center Outward

For smooth installs:

• Start by aligning the center of the graphic

• Press outward toward the edges to remove air pockets

• Use a soft squeegee if needed for larger pieces

• For multi-panel installations, overlap edges slightly to prevent gaps

Don’t: Stretch, Tug, or Force the Graphic

Magnetic sheets are designed to lay flat. Pulling or forcing them into position can lead to rippling, edge lift, or magnet fatigue over time.

Let the magnet do the work — and if it doesn’t lay flat, check for a surface issue rather than trying to “muscle” it on.

Do: Store Magnetic Graphics Properly When Not in Use

One of the biggest advantages of magnetic media is reusability — but only if stored properly.

• Roll loosely around a core (print side out)

• Store in a cool, dry environment away from direct sunlight or heat

• Lay flat or hang vertically to avoid creasing or warping

Don’t: Fold or Stack Unprotected Sheets

Folding magnetic sheets can permanently crease them. Stacking without liners or interleaving sheets can lead to print damage or loss of magnetism.

Use slip sheets or tissue between stacked graphics if needed.

Bonus Tips for Vehicle Magnetic Graphics

• Remove and clean graphics weekly to avoid dirt buildup or paint damage

• Avoid high-pressure car washes or extreme heat

• Use vehicle-rated magnetic media for better hold on curved panels

• Round the corners of your graphic to prevent wind lift

Conclusion: Simple Application, Long-Term Results

Magnetic media offers a fast, flexible solution for all kinds of graphics — from store signage to vehicle branding. But like any great print material, success comes down to the right installation process.

By following these do’s and don’ts, you’ll get more value out of your magnetic graphics — and keep them looking great through every swap, move, or campaign update.

Because in digital print, how you install is just as important as what you print.
