Good day, I apologize in advance for the language, I will most likely use the wrong terms. I used this chemical in the pool (link). The tiles started to fall off and I drained the water - the tiles continued to fall off during cleaning, upon examination it turned out that all my "putty" simply disappeared (see photo), and the layer behind the tile holding it began to crumble. I would like to know if I can restore this tile without buying a new one - I collect it and store it. I bought new putty and a means for holding the tile, I would be extremely grateful for a video example of how to do this. I understand that I am a beginner and ask a lot, in turn, I can share my experience of how I did it and what I encountered and contribute to the Internet and the forum. I took several photos of the pool and while I was doing them, some more fell off. Thank you
