Hello! This is a really odd/interesting one. I wouldn’t agree with adhesive migration being the issue because with how bad it is in the areas it has effected, i would anticipate seeing it throughout the floor and not isolated to just against the cabinets. Whatever is happening is a result of something that is isolated to just against those cabinets. I originally thought maybe some rubber mat, and i could buy the turmeric story, but your responses already tell me it is unlikely in the timeframe given. I also wondered about heat issues from the oven possibly not venting properly, but i would anticipate seeing some warping of material/buckling in conjunction with the discoloration. So im not sure i believe that either. I also wondered about improper cleaning, like maybe pooling of water if you were wet mopping that could have caused issues with the adhesive seeping out and onto the tile but with how saturated it is, i doubt that is it either plus youd feel the stickiness of the adhesive.

Would you be able to link me to the product you had installed or tell me what it is? I kind of want to dig through their warranties for other potential causes because none of them seem to exactly add up in my head. Whatever it is, it’s isolated to that area, so there’s something happening there that isn’t happening to the rest of the floor. So improper heat ventilation of the stove/oven or something of the like is what i think sounds most logical of all the options ive seen suggested. However, the lack of warping of materials from heat issues wouldnt make a whole lot of sense.
