Sorry for the delay. I did the job on the 25th of June. Started at 9am took 3 hours to remove 1/2 of the old seal with a multitool. Took 1 1/2 hours to do the other side. Slow learner!?
I tried the best I could to remove all of the old seal. Some was left on the back side of the coping brick, but not a lot. Most all of it was scraped off. It was very hard to get all of it off of the concrete side. If I had a wire wheel for my drill I could have really cleaned it up. I used a shop vac and vacuumed all of the old sand out of the crack because of the small pieces of old seal that stayed in there.
I poured new sand in the joint with a grout bag. I made a 1/2" by 1/2" tooth on the bottom of a clorox box flap to make sure I had it 1/2" from the top of the deck. I'm not very good at eyeballing a 1/2". That only took 20 minutes to run that around to pool.
Next I wet down the joint and put the new pool seal in 10' at a time because it was 100 that day. I could see the seal soaking up the water from the sand as I went along. Next set hose to mist or fan and lightly sprayed the seal with water 2-3 passes. I smoothed out the sand and wiped up the excess on either side as clean as I could get it. Took about 4 hours to do 107' of expansion joint.
Next day it looked perfect. 2 days later I was going to do this post but I noticed that I had a minute separation from the brick side of the seal. I contacted the company and asked what I did wrong. He said I either (1) didn't get the joint clean enough or (2) I didn't "press" the sand down in the joint hard enough. (1) I left more of the old seal on the CONCRETE side and that side didn't separate, so that theory doesn't work. (2) I did lightly sponge over the new sand in order to fill the void but I didn't press it into the joint. So?? maybe. he said you can go back and pre-mix some seal to the consistency of playdogh and press that into the crack, then wipe it with a damp sponge.
I'm at work right now,so I don't have access to the pictures I took and last week I was out of town at 2 different locations doing inventory.
Sorry for the delay but I wanted to get this written as soon as I could. I will post photo's later.
