Hello TFP community.
This is my first post but I've come across this forum virtually every time I searched for something pool-related (kind of like I always ended up on homebrewtalk when searching for homebrew info...). I did some searching across here and the interwebs but I have found conflicting or no information.
Here's my situation (wouldn't call it a problem quite yet):
I decided to replace my waterline tiles because many of them popped off since we bought the house end of 2013 (the pool was built in 2001 I think but was unused for a while by the previous owners). The pool was in fairly good shape but I think the expansion gap was not caulked right and moisture got in between [everything tile]. Last year I fixed the expansion gap but once I had removed all of the waterline tiles I decided to pry off the coping as well because I was sure the root of the problem was loose coping tiles (and right I was!). Now that I have removed about 75% of the coping, I have a few questions:
- I can't easily remove the remaining 25% of the tiles. I feel like I should though because there might still be underlying problems, right?
- When removing the coping some tiles came out with a chunk of concrete. Do I have to remove the concrete from the tiles completely and fill in the gaps of the pool beam to have an even surface to put the tiles back on or would it be OK do just put thinset/mortar on and use as-is?
- Can I use FlexBond (Custom Building Products FlexBond Gray 50 lb. Fortified Thin-Set Mortar-FB50 - The Home Depot) to set the coping again and use it as grout in between? If not, what kind of material is best suited for grouting the coping in a freeze/thaw environment?
Any other words of caution/advice are greatly appreciated!
