I'm constantly seeing pools with deck-o-seal that are deteriorating. The seal gets old, falls apart, water gets under the coping and all the tile starts falling off the pool. We are about to renovate a pool and replace the coping and tile.

Should I be using deck-o-seal for my gap? The coping will be pavers and the pool deck is half pavers and half a concrete walk.

What about poly sand instead?

Are all the new pools still using deck-o-seal?
