Its in a kitchen/diner so there is a big enough area with a lot of tiles and it could add 2 days extra labor to the job. Will the adhesive stick to the existing tiles or would you need to score/scratch them all first?
Make sure the tiles that are already in your kitchen are well stuck down.
Flexible adhesive is required when tiling over tile.
It is 30-35 euro per 20kg bag.
But in the long run it is better to take the tiles up and put leveling compound down and then the rapid set adhesive 20kg bag would only cost you about 20 quid a bag.
