I had to remove a toilet because I had to repair a piece of ceramic floor tile. When I put it back, I cinched down the toilet bolts and one kept on tightening by did not get tight. I took it off and saw that one of the slots was rusted out. I tried to unscrew the toilet flange ring and the screws were rusted on so I took an angle grinder and ground the heads off and cut the ring off. I replaced it with a ring that is in two parts or halves. To get the old one off, I had to pull out some of the old screws after the heads were off or pound the screws in further. I used the same size screws as replacements but most of the holes were larger so the screws would not tighten or hold anything. I tried using Durham's Water Putty to put in the holes . I mixed pu the powder with the water in the kitchen and had a nice paste. By the time, I got to the bathroom, which was 30 seconds away, the putty was already starting to set and got somewhat crumbly. I tried to stick it into the holes with both a stick and a coat hanger end, and it helped a little bit.but I had to work fast because it was setting up more and this was no more than 2 minutes after I made the paste. The directions say it starts to set up in 5 min. I set the toilet on.and started tightening up the toilet bolt. One got snug and the other did not get tight. Maybe I did not tighten it enough but I suspect I did tighten it enough. My suspicion is that the tightening may have caused the screws to come out that were holding the ring on. At this point I decided to ask the forum. I did not turn the water for the toilet back on.My questions are: What should I do now? Tighten up the bolt to see if it gets snug? Take the toilet off and check the screws? If the screws are loose, how can I get them to seat firmly? If most woodworking projects, I would jam splinters of wood into the holes to tighten up the screws but there are six screws holding the ring on. Any suggestions? Thanks.
