I don't know the name of the person who laid the floor tiles in our house but if i did i would tell you so you don't use him. Not long after they were laid cracks started to appear just by the weight of us walking on them. After going around tapping them with the plastic handle of a screwdriver many of them gave off a hollow sound meaning not enough cement underneath them. If you intend to put a car in your garage i would forget about tiling it. Oh i just also remembered, don't get whoever did City mall tiling.
That reminds me a long while back, just before my wife and I married, we were sitting in the first floor cafe of a newly opened Robinsons ( just corrected by the boss ) shopping mall in Cagayan de Oro. I noticed some of the tiles started "popping" and coming towards us, turning to my wife, I half jokingly asked, are we experiencing an earthquake? She never said a word, but jumped up, ran straight over to the escalators knocking everbody out the way, the escalator was coming up! Needless to say, I was right behind her and she never stopped till we got outside, then blamed me for frightening her!! ( when the building didn't fall down) The security guard after we explained, replied "It's ok it happens alot, when the building expands"!!!
Too many folks use cement instead of tile adhesive...tile adhesive is much more expensive but well worth the additional cost. Using cement will normally end up having tiles pop up, cracked grout and needing replacement after the floor has started taking weight. For hollow spots, that is normally because the concrete slab wasn't properly leveled and the installer didn't explain this to the home owner or decided to hide it. We lost touch with the folks that did the tile in our house so no help there. Can't say they would have been great on their own...I was right there to explain how things needed to be done. Best of luck! Shawn
Have you considered using an epoxy resin for the garage floor? It could be a far better long-term solution than tiles.
Probably cheaper using epoxy resin and quicker. I was going to suggest using rubberized pint. Davies Acreex
Agreed - just mix it and pour it yourself, as long as the substrate floor is clean and grease free - also, as it goes on as a liquid, it's self levelling.
