Prep for solid floor tiles

[hopefultiler]

Hi All. first post on interesting forum, learned loads already so thanks.

I have a utility room floor to tile with 30cm square tiles. A new kitchen has already been fitted including units in the utility. The existing floor is 6 inch tiles on a concrete floor. They are rock solid, when you try to move them they send razor sharp splinters everywhere so my plan is to tile over them.

I know this is not ideal from what I have read here but given the fitted units in place it is the easiest option. I believe the plan of attack should be clean, prime and fix with flexible adhesive. I have a Wickes, Screwfix and Tile Giant nearby, could anyone recommend the best products to use please?

Thanks, Tim

I would opt for TileGiant for materials and a single part flexible adhesive for fixing.
