Answer: yes, if the screed is old or poorly made.

The laying of the tiles must be done on a flat floor. If the mortar screed was done recently, it should not be necessary to make a leveling work, unless the work has been botched. If the screed is older, time may have had its effects. It will therefore be necessary to check that it does not present any irregularities or difference in level. In case of minor defects, less than 7 mm in the professional environment, a leveling is not compulsory. All you have to do is scrape off the traces of glue or mortar, and fill the cracks with plaster. On the other hand, if the difference in level is greater than 7 mm, or if the screed is dotted with very many holes, smoothing over all or part of the ground will be essential.
