thinset on thinset?
Remove the thinset??? You're kidding! There isn't a build up of thinset on the floor, just a skim coat from the remains after he removed it once he realized he had no more tiles.
If there was a build up, (the normal amount) I don't think he would be asking the question, do you? It's the same as treating the seams of the CBU.
