If you refer to bond as in electrical bonding grid then yes we did that before the pavers. If you refer to bond as in cement then no. Pavers sit on a compacted bed of about 2" of concrete/coarse sand. Under the sand there is 7" of landrock, compacted as well. I rented a compactor for $45 a day. If you are installing your pavers in top of an existing concrete deck then I am not sure if you need cement of not.
Heads up: so far the only thing I am not completely pleased with is the required drop rate of the slope of the deck. The code says to give 1 in of drop every 4 feet. I did that to the dot and the end result produced a visibly skewed down hill on the 14' side of the patio, which is the longest drop. If I were to start over again (which I may on that side if I go too crazy about it), I would have probably done 1" for every 5.5".
Yesterday I worked a bit on the deck after I returned from work. Look below at the progress so far. The pavers on left are out on purpose because I need to place a deck drain there. I am also trying to figure out the best way to make the cover of the skimmer be as flush as possible with the surface.
