information on fixing a bad tile job
Good morning, a good client of mine wants to fix her tiled kitchen floor. Her problems with the floor were loose or broken tile and cracked grout all over. I removed 5 sq ft and the tile was not bonded at all. I could reuse the tile , it was that clean. Under the tile tile the thinset was bonded to the concrete subfloor that was installed over electric radiant floor heat over a wood framed deck. This job was installed 15 years ago and has had issues from day one. The thinset is randomly cracked and looks like it may be cracked down to the wooden sub floor 3/4 inch T&G plywood. I will remove the whole floor this week to inspect the whole floor but i expect ther same. This floor was installed in the winter and i expect that the thinset skimmed over becuase of the radiant floor heat causing the zero bonding. The cracks in the concrete maybe happed because the concrete was still green when installed. We would like to retile but we are not removing the concrete and electric heat in the concrete. When the whole tile floor is removed i will see if the concrete is bonded to the wood floor and solid to walk on. If that floor is bad we will not tile. If that floor is solid we would tile. Can i be confident that if i use a renforcing membrane over cracks and thinset the new floor in that it will proform correctly. We plan on not using the floor heat as it was not working well any way. Any help is Appreciated. Thanks bford
