Replacing single floor tile

[jacoscar]

I’m renovating my bathroom and I’m taking out the stud wall to install a pocket door. The door opening will be more to the right. I’ll be installing the same tiles as the hallway by continuing the pattern. The tiler who installed the tiles previously used a decoupling membrane. Will I be able to remove the tiles that have been cut around the wall and replace them with full ones?

Presumably you can score through grouting and the membrane underneath, leaving the tile and its underlay to be removed

So should I aim at removing the tile with the decoupling membrane and not attempting to leave the membrane in place?

 

[blup]

I’m assuming the tile has been bonded to the membrane.

What was the name of the membrane used?

Schluter DITRA 25

I can see around 5mm between the concrete and the tile (comprising a layer of adhesive, the membrane and another layer of adhesive)

 

[robinbanks]

Yes, Ditra is a plastic membrane with a fuzzy side that is bonded to the substrate with tile adhesive and a network of pockets that are filled with adhesive that bonds to the tile side.. It would be easier to detach the tile and membrane from the substrate I'd say, then use mechanical assistance to reclaim the tile

The tile will be discarded, unless it can be used somewhere else.
What trowel should I use below and over the membrane?

 

[jacoscar]

I was able to remove the tile without damaging any other. The membrane seems still bonded to the subfloor, still safe to use?

 

[robinbanks]

Is it still bonded down well?
Have you got a trowel that's smooth on two sides and notched on two sides? Use the smooth side to press adhesive into all the voids in the mat, filling them up, then comb out more adhesive into notched lines like normal. If the other tiles are sitting on a 3 mm bed use a 6mm notch trowel, 5mm bed, 10mm notch etc
