Looking for some urgent advice on floor tiling! We laid 600x600 tiles a month ago with already made adhesive but it’s still wet and the tiles are now cracking abs bracking... please advice what’s the best adhesive or products to last 600x600 porcelain floor tiles thanks

Are we talking ready mixed adhesive in a tub ?

Yes which I’ve now found out is rubbish! Been advised to use s2 flexible? And re-do it all again?

Ready mixed adhesive will never set under a tile that large, you will need to take up and relay with cement based flexible/ slowset / fastset adhesive depending on the sub base.

If they are still wet then they will come up and clean off easily...
clean back the timber floor ....SBR it...... overlay with an anti fracture matting ( sticking it down with the same adhesive ),,, then re-tile using an S2 adhesive ( more flexibility than S1)....
Being as your floor has been laid already ... cuts are pre done ;so should be fairly straightforward
Good luck👍

Gonna have to remove the tiles, and clean them up PERFECTLY clean on the underneath to remove any adhesive residue, as the new and proper cement-based adhesive will need to bond to the tiles.

Board the floor using Hardibacker or other cement board if timber. Possibly level the floor as you are using fairly large format tiles. Tile away using an S1 or S2 powder flexible adhesive.
