Hi,

I had my house tiled almost two years ago. The tiles themselves were not the best quality, just an affordable option, but my tiler did a good job. Now almost two years later some strange shadow looking stains have started appearing all over the tiles all over the house. It started with one stain so I though that one tile might be dodgy but now they’re appearing all over the house. I’ve attached some pictures right after mopping the floors. The stains themselves don’t have any texture. I’d really appreciate any help and advice on how to get rid of them. 45F980D9-ACE1-47ED-AA8A-FEC505B47C9D.jpeg

Do the stains appear clearer after getting wet ?? As I can only think that you have a porcelain tile that needs sealing !! ??

To be honest, no. They appear the same before and after getting wet. I did some googling and I think the tiles I have are sealed. The stains do seem to be getting darker and more noticeable over time.

Yes probably need resealing and again over time

It could be from the tile adhesive used. The stains seem dark so maybe a grey adhesive was used rather than a white one which would have been my preference for cheaper light tiles. If they are staining from the reverse then cleaning and resealing wont really do much at all
