Rolling a magnetic sign is a convenient storage method, but it can create a permanent curl that leaves the sign with raised edges. While rolling the sign in the opposite direction may appear logical, it often weakens the magnetic coating, especially on commercial or heavy‑duty signs. The following steps use heat and a flat metal surface to restore the sign’s original flatness while preserving magnet strength.
Carefully unroll the sign, holding two opposite sides but leaving the corners untouched. Pulling the corners can stretch the magnetic material and degrade its performance.
Place the sign face‑down on a flat metal surface. The metal provides a rigid base that helps set the sign in a flat position.
Using your hands, press down on the sign to eliminate any remaining bends and ensure full contact with the metal surface.
Set the hairdryer or heat gun to a medium setting. Heat the sign to gently soften the paper or cardstock without scorching it, which helps the material conform to the flat surface.
Hold the heat source about 6 inches from the sign’s face and move it slowly across the entire surface. This distance keeps the temperature moderate and protects the magnetic layer from overheating.
After flattening, store the sign on the same flat metal surface. This practice minimizes future curling and keeps your sign ready for display.
Always keep the heat source on a medium setting and at least 6 inches from the sign. Excessive heat or close proximity can weaken the magnet or render it ineffective.
