Cracking kitchen floor tiles!!!

Hope these help.

I have been there myself. What I did was duct tapped them down well, then primed, painted and sealed. I lived like that for two full years. You gotta do what you gotta do.

see if you can find a matching paint (water base acrylic) at Michaels or Hobby Lobby, in the craft aisle. Then get a toothpick and paint the cracks and using a soft cloth take off any extra. I did this when we had our house up for sale and no one ever mentioned seeing any cracks.

How to Repair Holes or Cracks in Ceramic Tile

Patching unwanted holes in glazed tile like this can be a tricky proposition. Here's a solution that may not always be perfect, but will make a big improvement. Polyester resin or auto body filler, often used to repair car bodies. Mix up a small batch by adding some hardener and stirring it thoroughly. Using a putty knife, press the resin into the hole slightly overfilling it. Then just as the material begins to harden while it's somewhat rubbery, trim off the excess with a razor blade.

Next use 600 grit sandpaper to sand the filler smooth. Wetting the paper with water makes it work best. Now it's time to try and match the color of the tile. A porcelain touch up kit which is available at most home improvement centers comes with several different colors of paint. You can also use artists acrylic paints available from Michaels, Hobby Lobby, art supply stores, and online.

The trick here is to mix these different colors together until we come up with one that matches the tile. Apply the paint with a small brush. You can test it on a nearby tile. When you get it the way you want it, then just paint over the patch and let that dry. Give it one final sanding with that very fine sandpaper and you'll have, well, maybe not a perfect match, but something that's a heck of a lot better than what you started with.

It could be that your problem lies with settling which would cause the cracks. It might pay to have this checked out or you will continue to have cracks and windows and doors that do not operate right. We had this problem so been there, done that.

If the floor was done incorrectly then it needs to be fixed or the cracks will continue. In my house the previous owner didn't do the plywood under the tile. They also didn't check for the factor of how much the floor weighs we had to put up molly columns. So we have lots of cracks but we just put up with them as they don't really bother me. Remember while DIY can be done I have that a professional consultation is sometimes worth its weight in gold.
