Tile on tile

[Paul J]

Hi. Hoping you al. Can help me.

I have an issue where I had a bathroom built and a shower installed. The shower is tiled floor to ceiling on three walls with a shower screen on the 4th side.

I had issues with the tiles that the fitter installed ( he has since disappeared so I can’t go to him to resolve ) and I thought I’d try to do the bits myself.

Anyway The grouting in the tiles is weak and in places has gone leaving gaps between the tiles. I have dug out as much as I can and regrouted Not my issue is the alcove he built and tiled The base of the shelf is angled backwards leaving water pooling at the rear of the shelf. I think I have a solution without ripping all the tiles out I was going to lay another cut tile ( with an insert to raise the back so the water drains out ) but my question is. Can I tile on tile in the recess or do I have to prep the base tile and if I do need to prep it could anyone let me know how and with what These are very glossy porcelain tiles

I think you have a bigger problem if grout is falling out. Is there any movement in the tiles ?

No. There’s no movement at all thank god and they are heavy tiles. I think it’s the way the adhesive was applied when fitting the tiles but I hope that I don’t have to start from scratch. So for now I am doing what I can to stop the leak.

Could stick the new tile with silicone or similar over the old to wing it , tile adhesive does stick to glaze but is not really bonded , could scruff the tile to be covered with the grinder if want better bond to old tile face

Leak ? from where ?

Leak ? from where ?

This I am not sure of. So it’s belt and braces and redoing all the seals ( regrouting and sorting the angle out on the shelf ) then once all done test for leaks again. If it still leaks then call a professional

This is exactly what I have done. Fingers crossed that after doing this yesterday it’s all bonded strongly today
