Actually thats not entirely true. I've installed several self stick
tile and the secret is to buy a small notched trowel and vinyl tile
adhesive. Spread the adhesive with the trowel just as you would
non-self stick tile. Remove the backing paper and lay the tile. The
extra adhesive allows you to slide the tile in place where as if you
didn't use it, once it's stuck your stuck. Also the adhesive adds the
right amount of extra stick so the tile wont move in the future. Some
adhesive will come through the seams when you lay them, have a wet rag
handy to wipe it up.
