Step 4Safety Coating the Magnets
You can stop at step 3, but I chose to coat the magnets with plasti dip for three reasons:
1) The magnets are brittle and easy to break if you drop them.
2) I didn't want to scratch up the surface of my new refrigerator.
3) The plasti dip acts as a secondary adhesive, helping to hold the magnets on. In theory at least.
If you choose to do this step, please see this tutorial first: http://www.kjmagnetics.com/rubbercoat.asp. It does a good job explaining the general procedure I used.
1) Pour your plasti dip into a shallow plastic container. A metal one would be foolish indeed. Don't use all of it at a time, since you'll probably do several batches.
2) Stick the tile to the broad side of the bolt - the magnet won't be strong enough to hold the tile and bolt together by itself, so...
3) Stick a spare magnet to the opposite end of the bolt. The two magnetic fields will attract each other, and your bolt handle should be pretty sturdy.
4) Dip the magnet side of the tile into your plasti dip. Go slowly and try to cover up half of the sides of the tile. Spin the tile around to get all the crevices. Avoid air bubbles.
5) Turn the tile right side up and attach to your sheet of metal to dry. The plasti dip will look pretty thick, but don't fret, when it dries the viscosity will make the rubber coating form fit around the magnet and tile. If you're worried, do just one first to see what I mean.
6) Allow 3-4 hours to dry before taking the tiles off the bolts. I only needed one coat, but you may want to do some touch ups on any that had an air bubble in them.
