Properly clean and prepare deck surfaces,

I like the above idea a lot but yes, you can use a crack filler to fill the cracks and then tile or paver over it as normal. I did pavers over concrete. Worked out great.

ours was inside/under a pool cage so the edges needed to be secure. We used a mortar product. I'm sorry I don't remember which one. Whatever the store suggests will work. Then we laid the others down inside the edging. When we did the Outside, we had to go over a sidewalk spot for part of it. There we used the mortar stuff as well. When doing that, permanently affixing them, it's best to dip the paver in water for a minute to keep it from sucking the water out of the martar too quickly. I would do the same with quarry tiles. Oh, the reason for the edge is so that any Cut tiles will be on the inside of the boarder and therefore less noticeable. Most people then brush white sand into the cracks. We chose not to on the inside because we didn't want it washing into the pool. The outside we used sand and have to redo it pretty regularly due to heavy rains
