How to make magnetic boards
Replace cork and tack boards with a magnetic board. (note board image by Hao Wang from

Magnetic boards are thin mountable magnetic surfaces that you can place anywhere that you wish to be able to stick magnets. With a magnetic board, your refrigerator doors and panels will be free of magnets. Materials required in the construction of a magnetic board are fairly inexpensive and the construction is simple enough that a basic crafts experience should be sufficient for a fairly successful project.

Skill level:

Things you need

  • 3ft x4 ft sheet of galvanised flashing
  • 38 inch x 50 inch sheet of foam core board
  • Craft knife
  • Tin snips
  • Spray adhesive
  • Ruler
  • Pencil
  • Drill and 1/4-inch or smaller bit
  • Small screws
  • Screwdriver
  • Assorted magnets
  • 100 inches of 2-inch thick self-stick vinyl border tile

  1. 1

    Cut the foam core board to a rectangle 38 inches x 50 inches using a craft knife. Cut the galvanised flashing to a 3ft x 4ft sheet using a pair of tin snips.

  2. 2

    Spray the rear of the galvanised flashing with the adhesive. Position the flashing in the centre of the foam core board so that the board extends 1-inch in all directions around the galvanised flashing. Press firmly upon the flashing and hold in place on the foam core for 30 seconds to set the adhesive in place. The foam core board adds padding to the board and prevents the metal edges from cutting.

  3. 3

    Place a small pencil mark 1-1/2 inch diagonally from each corner of the foam core and flashing base. Drill a small mounting hole through the base at the marked points.

  4. 4

    Cut the vinyl border tile into four 1-inch thick strips, two of the strips 50-inches in length and two 37-inches long. Place the strips along the 1-inch borders of foam core surrounding the flashing as a decorative border, covering the entire perimeter.

  5. 5

    Wait overnight in order to allow the adhesive on the board to cure. Mount the board in place using the screws to secure it to the mounting surface. Place the magnets onto the surface for use.

Tips and warnings

  • Wear work gloves when handling the flashing to prevent cuts from sharp edges and corners.
