We had our kitchen area professionally tiled several years ago. A place underneath a chair created a white spot that began to grow.
We tried cleaning it, but eventually determined the color was wearing. It looked horrible. We sent pictures to Congoleum, they claimed wear was impossibe, and that we were obviously using a caustic cleaner. They said paint it.
We replaced the tile with the same lot. Same result. This is my third attempt.
When I can afford to replace my kitchen tile it will not be with a Congoleum product. Their products lack integrity, So does the company.
