I'm is the process of removing my mortar, because I live where in the summer it could reach about 120 degress easily. Thre floor was laid about 2 years ago and the tile started buckling this summer. So, I think the adhesive has dried out. I'm not sure if it wise to replace the tile or not. I don't want to do this again.

I hope there isn't mortar on those tiles...

If they are ceramic it should be thinset and it doesn't "dry out"... and there should be GROUT between them...

smoothy is right. U do not use mortar to install ceramic tile, u use thin set.

If u are getting buckling in the tile, u have a problem with what tile and thin set was laid on. This would be the surface under the adhesive. This is usually caused by not nailing sub strait with enough nails and excess water in thin set.
