my plan is to mix a extra thin (watery) grout mixture, pour into 3mm grout gap between tiles, then use an air gun (compressor) to blow it hoping it injects itself into the hollow spaces. Will use quality wide 3M tape to keep it from shooting back out. Once i get it “full” then will use an epoxy based grout mixture to get extra sttrength. My tile guys were cheap, and so too the quality of their work. WARNING. For those using tile levellers DONT skimp on the tile adhesive/thinset. MORE is better. Live & learn
I was thinking that as well, but I followed the instructions calling for just one hole and it was great. I bet the air finds its way one way or another.
Fair point, fix it as in come and break the hollow tiles out, jackhammer the old thinset off the concrete, and reset it, come back the next day or two and grout it? Massive inconvenience and this was an easy fix that has lasted. For someone else, calling back and doing the longer more intrusive repair may make sense, just not for me.
If my tiles were loose enough to remove, which i did, can i use fix a-floor to just glue it back down without having to remove thinset and all the old cement from floor and tiles?
It doesn't say to use it like that. I do not recommend it. If your tiles are completely broken loose like that I think I would do my best to break up the thinset and get it as clean as I could, then re-thinset the tile down and grout. It sounds like a lot of work but it wont be that much. You can do it!
I think that would be preferable however my tiles are 24"x24" and hollow sounding only in the center. I had my doubts about the fix-a-floor pushing all the way into the center with a seemingly solid thinset bond around the outside.
I have tiles that definitely need this. But the grout has broken down in some places. Any suggestions how to use without the product just coming straight out the grout lines rater than going under the tile?
