I am laying Ditra over concrete which previously had carpet. I am using Ditraset to lay the Ditra but the floor still has some of the glue residue from the carpet. It isn't much and we tried to scrape it but I am concerned about putting thinset over it. Will the thinset bond fine to that or do I need to coat the floor with something prior to thinset? If so, what should I use to coat it? Thanks for the help!
