Looking for advice on flooring. We want to re-do our entry way and remove our tile and use vinyl planks. I pryed up a couple tiles yesterday and there is the orange DITRA tile backing below the tiles. I assume the DITRA was laid down with a thinset first. What do I do? Remove the DITRA and thinset before laying the vinyl? Lay leveling thinset over the DITRA and then lay the vinyl? What is the correct way to do this?
