Hello,
Settling in several areas of our house has caused the silicone joints to crack.
Yesterday, I tried to repair the first section in the utility room and completely removed and re-did the silicone joint on one wall. However, removal was more difficult than expected because the vertical side couldn’t be properly cut with the joint cutter; instead, it pushed into the cavity between the tile and the tile baseboard. So, I had to remove not only the silicone in the joint but also the silicone from the cavity behind it. The silicone sticks very firmly to the underside of the tile baseboard and the wall behind it. In some places, I could only remove it little by little using needle-nose pliers. Considering how long it took me to do 3 meters (10 feet) of wall, I estimate it would take days to do all the joints in the house. That can’t be right. Are there other methods? Does a multifunction tool with a segmented saw blade or scraper work better than a joint cutter?
Has anyone ever tried applying a new layer of silicone with a larger joint triangle over the old silicone joint?

If you are doing it from scratch, be sure to use a silicone cord with the appropriate diameter. This cord is pressed into the gap, which prevents adhesion on three sides. As a result, the silicone joint remains more flexible. Additionally, this reduces the tendency of the silicone joint to crack and also saves a significant amount of silicone.

cut off What a dreadful neologism

somehow treat it so that the new silicone adheres there, or should that not be a problem? I cleaned those areas with vinegar, roughened the old silicone, and then applied new silicone. But only where I noticed minor detachment from the substrate.
Hope I understood your question correctly

Do you need to treat the areas where silicone was cut away to ensure the new silicone adheres properly, or is that not necessary? I used silicone remover for this. Let it work for a while, then the residue could be scraped off.
