Removing adhesive from porcelain

[Mistertrubbs]

I have just removed about 30 600x600x10mm porcelain tiles which had been applied over existing tiles with no keying at all.The hardest part of removing them was not having them fall on me.I now have to prep the wall and refix the tiles.My problem is,how do I get the adhesive off the back of them? Looks like a bagged cement based adhesive.Any guidance would be appreciated.

would be cheaper to replace the tiles and have you removed the existing tiles and when you do what surface are you tiling onto ?

if its cement based adhesive i think yo may struggle the way to tell is to soak one in hot water for a while if tubbed adhesive it should come off if not as above may be easier to buy new , if you have the time and pacience try and use a grinder,good luck
