Perfect for making flat lightweight items magnetic. Magnet requires direct and full contact with steel for maximum hold. For best results: 1). Allow magnet to reach room temperature then cut magnet with heavy duty scissors or hobby knife. 2). Apply magnet's Magnetic side to large metal surface for several hours to flatten curl. Do not roll magnet strip in opposite direction to remove curl. 3). Clean applicable surface for adhesive with isopropyl alcohol and allow to dry. 4). Peel-off liner from one side of Double side adhesive tape provided in the pack and paste on non-magnetic side. 5). Peel back liner from the other adhesive side and place item on adhesive. 6). Apply adhesive to surface with firm pressure 7). Allow adhesive to cure for a minimum of 24 hours or 36 hours to reach maximum bond with surface. 8). In some cases additional Adhesive maybe required. Instructions : 1). Magnet designed to hold on one side only directly to flat steel surface. Multiple Poles are evenly spread across its surface to prevent sliding. It does not hold well to other magnets. 2). Magnet to be used on flat, smooth ferrous steel, without layer of material between magnet and steel. Minimum recommended length for magnet is 1" 3). Adhesive covered by peel-off liner is on non-magnetic side. Adhesive is pressure-activated, permanent, acrylic type with initial tack and minimum of 24 hour cure time requirement. 4). Perfect for making flat lightweight items magnetic. Magnet requires direct and full contact with steel for maximum hold.
