A few days ago (Wed) I laid 30x30 (approx) floor tiles to a wooden base (2cm ply, very solid) after removing the old tiles.
My first mistake was to use Unibond wooden floor premix stuff from B&Q.
My second mistake was to think it had gone off enough to grout (36 hours later)
Tiles flexing... grout cracking...
So have lifted it all up and salvaged most tiles and plan to do the job properly (after some research).
So I will be visiting Tile merchants to see what they recommend I use (adhesive wise).
Main question here is....
The surface on the floor is now a few mm of Unibond stuff spread all over the floor with 3-4mm lines in from the trowel. I did not try to remove this as some of it was VERY hard whilst some was soft, so am allowing it all to harden with the thoughts that this will provide a flatter surface than digging some valleys out of the soft stuff. Now this stuff does seem to set very hard, very quickly now the air can get to it.
Should I just use this as my base? It is pretty flat except for the "tram lines" from the trowel (as one might expect after the old tiles were used to flatten it into place) and it's stuck to the wood so well it rips the wood when trying to remove it. I cannot really see an alternative except to sand it off (which would be an epic).
Also will the old adhesive kick out fumes for a while and might this affect the new adhesive I use? I would like to redo tiles on Mon.
