Hello everyone,
In our new build, we chose a lime plaster with reinforcement mesh based on the recommendation of our plasterer. The process was as follows:
- Base coat of lime plaster (approximately 15mm (0.6 inches) on average)
- Insulation, edge insulation strips, underfloor heating
- Screed
- Drywall construction (gypsum board ceiling on the upper floor)
- Lime plaster with reinforcement mesh (approximately 5-6 mm (0.2-0.24 inches) on average)
- Fine plaster (about 1 mm (0.04 inches)) – still pending
This sequence caused the following issues:
- Edge insulation strips were cut and plastered over
- Gypsum board ceiling was masked off, causing damage to the paper surface when the tape was removed
- Screed became soiled with plaster and partly damp (amount of water unknown)
How serious do you consider these issues? Does the screed need to be sanded again before installing the flooring, or is cleaning plus priming sufficient?
Thank you and best regards

I see several issues here.
The drywall partitions should have been covered at least at the lower part before the screed was applied.
A perimeter strip should be installed on the drywall partitions, with the screed placed against it.
The perimeter strip should be left in place until the tiles or floor covering are installed; otherwise, a connection forms between the floor and the wall, which the strip is meant to prevent.
The floor to walls and ceiling to walls need to be decoupled.
At the very least, it would have been better to wait until after the screed was laid to cut the perimeter strip to about 2cm (1 inch) above the screed, and then plaster or otherwise finish the walls.
There could now be cracking because the decoupling between wall, ceiling, and floor is no longer fully effective.
Of course, the masonry walls should be plastered before the drywall profiles are mounted on them.

For my construction project, the steps were as follows:
Plastering the exterior walls
Building the complete stud walls, single-sided boarding,
Pulling all cables and installations into the drywall stud walls,
Final double-sided boarding,
Laying the insulation and edge strips, installing the underfloor heating
Pouring the screed
