Question:

Broken grout on bathroom tile floor?

We have small ceramic tiles on our bathroom floor. They are varied in shape and size (see photo).I think that these tiles originally came with some sort of netting on the back when they laid the floor and they added grout? I believe I saw some extra tiling somewhere in our home and this is what I had found.Anyway, the grout is breaking up between some of the tiles and some of the tiles keep popping out. I have two questions, If I regrout them do I put it on the bottom of the tile too and does that make the tile adhere to the floor?How would I get the grout to match what‘s already there, it‘s a medium brown gray. Not sure if it started out that way or became like that over the years. Would it look funny if the grout didn‘t match? How could I get it to match?

Answer:

The plastic mesh was there to make it easy to set a lot of small tiles as it they were one big tile. If a tile is loose, you have to chip out all the old adhesive on the floor and on the back of the tile (or use a replacement tile if you have some) and use fresh adhesive. This is not the same as grout. The two common tile adhesives are called mastic and thinset. For small repairs, I'd go with the mastic. You do the best you can to match the color. You can get a color palette at any home store, bring it home and pick the closest match. You should probably try to clean some of the grout as best you can with bathroom cleaners and bleach to see what the original color was.
no, reglue tiles, regrout after cleaning out old stuff. 2 step process
