I began my pool remodel in May, and had a number of stumbling blocks, but now the coping and tiles are on. They built up the mortar on the bond beam as much as 3 inches, but more like 1 1/2" in most places, before sticking the 12" X 24" precast coping with thin set. I am having paver decking installed and using polymeric sand for the joints.
My first question is: before the pavers are installed, should I attempt to waterproof the backside of the pool where the mortar buildup is showing? I know water will get between the pavers and the coping with hosing down the deck, and occasional rain. The pool is on the north side of my house so half of it is in the shade all winter. Although we rarely get below 32 temps, occasionally we do, and I have had ice on my pool. This is Las Vegas. I was thinking about painting on an elastomeric, AquaDefense by Mapei, before they come to install the pavers.
Related Question: There seems to be conflicting thought on installing an expansion joint. I had tiles fall off my original, starting on the north facing side which has the decking wedged between the pool and my house. Expansion joint and the elastomeric?
Any thoughts on this would be appreciated. I was 30 when the original pool was built, and now I'm a senior citizen; I want to enjoy my pool instead of dealing with too many problems! Thanks, Jackie
My pool is 15,000 gal, 15X30, gunite/plaster.
