Pool Coping Tiles Laying Terracotta Pool Coping Tiles?

Laying Terracotta pool coping tiles? - pool coping tiles

I tried in vain to meet at the pool tables, was recommended by my pool twice, using sand and cement mix with an additive, and twice set the tiles, the tiles have a good backup, that is not a rough surface for better grip, I think it is probably half the problem. Is there a rubber adhesive on the market, which also is waterproof and will not be swallowed up by the chlorine in the pool to be?
