Re-grouting tiles

albany

Hi, i'm trying to regrout an area where it's loose. I took out the broken grout cleaned the spacings.etc..For some reason when the new grout cures, it doesn't stick to the old grout, and later on cracks again due to the vibration of the floor. I used the latex ahesive to get more flex, no change.
Thanks for any help.

Sorry to be the bearer of bad news---but you are describing tile failure--not grout failure.

Those tiles are moving---so the grout will continue to fail until the tile is installed properly.

Tell me about the tile work----what kind of floor is under it? What is the underlayment ?

I've worked on houses where someone installed tile over partical board, hardwood floors, 15 lb. roof felt, loun, peel and stick tile.
Non of which are exceptable underlayment.
The customer kept asking me to remove the cracked grout and redo it. You try and explain to them why it's failing and all of them said they could not afford to redo the tile. I make them sign a paper saying I told them it would not work and they still had me do it. Everyone of them failed again and expected me to go back and redo it for free, so I just stopped doing it at all. Tile is a one shot deal and 90% of it is in the prep work.
We had one that we removed all of the tile with nothing more then a flat shovel, no wonder it was cracking.
