This is the answer to the question Do the interior walls need to be plastered first before screeding the underfloor heating?
Revision 1
Yes, this is already a problem if the wall plaster is laid after the screed.
Just do it this way:
Typically, heating screeds require a 10mm thick edge joint before plastering the wall. When laying the screed, let it rest all around the brick wall, ideally on 20 mm thick screed strips (double) (10 mm each, which should be installed to prevent slipping). If wooden strips are used, remove them after the screed mortar has hardened and replace them with 10 mm thick adjustment strips before plastering. Two-layer adjustment strips also remain in the joint chamber in the future, wall plaster should be applied only up to the top edge of the screed.
For this purpose, 5 mm thick screed setting strips or MDF strips can also be laid at the floor/wall transition (i.e. lying on the screed surface for protection, the setting strips are close to the brick wall) while the wall plaster is being applied.
It's a little more work, but it will all work out!
