Got a job on just now where im levelling out a kitchen for a customer using bonding coat. The customer was done by some idiot who tiled their kitchen and put the tiles on the wrong way and made a right mess of the job. They have took every tile back off and ive prepped the walls for bonding out. Question i have is can you tile onto bonding coat if you let it dry right out? or do i need to apply a finish of multi to tile onto? Dnt know much about tiling as ive never done it.
