if i pry em up i am afraid they will pop into two pieces, has anyone ever heard of or tried injecting some sort of adhesive under a tile to rebond it to the floor?
i have thought about epoxy resin using a syringe?? like we did in composite repairs?
oh and the looses ones are different from the others in color if it helps
I am not a tile mechanic, but I have installed over 800sq ft of ceramic tile in my home. I have found that the best way to repair this type of problem is to remove the loose tile clean the area smooth re-cement and and install a new piece of tile. The tile has a series of ridges on the bottom to help lock the tile in place in the cement, you may be able to inject a resin between the floor and tile, but If you do not fill the void completely you will end up with a hollow spot between the floor and the bottom of the tile, the problem in situation, If something falls and hits this area it could crack the tile. FYI before I started my tile projects in my house, I spoke to some tile mechanics and Lows for tile size selections, they both recommend to go with tile no bigger then 8x8's they said that the problem with tiles that are bigger have a tendency too break easier. I guess, if you compare this to bath room tiles that are on the floor most of the time they are smaller then 6x6, the more tile under your feet per step the more durable the tiles are Vs one foot on one tile. This is best suggestion I can come up, I hope someone else has a better Idea, Good luck.
