ᐅ New Construction: Having the Concrete Ceiling on the Ground Floor Plastered

Hello everyone,

We had the joints and larger holes repaired by the drywall installer. First, they applied filler, then fiberglass tape over it, followed by more filler, sanding, and then another round of filling and sanding.

After that, the ceiling was coated with a fine textured plaster using a roller. It looks great and has been holding up perfectly for about 4 months now.

With our ceiling, painting without filling in the holes was not possible. I painted the HAR white. There were small black holes all over, regardless of whether a brush or roller was used. We therefore covered the rest by wallpapering with fiber fleece.

Yes, it always depends on the quality. For us, both the basement walls and the ceiling on the ground floor were smooth enough after filling joints and painting to be painted directly. At my in-laws' place, the basement looked completely different.

We have just reached this stage of the project.

We have a precast concrete ceiling, and in the main room (kitchen/dining/living area) there were three joints. The ceiling already has tiny cracks, which unfortunately became very visible after applying the primer.

The joints were properly filled by the drywall contractor.

For the past two days, we have been applying non-woven wallpaper to the ceiling. Tomorrow it will be painted. We are very curious about the final result.

Our neighbors inspected our “work” this evening. The overall feedback: good idea. Their ceilings (2–5 years old and painted) have developed similar small cracks.

Cost for the wallpaper: just under 70 € (euros). It is a standard, lightly textured non-woven wallpaper from the home improvement store.
Paint: Caparol Indeko plus, white.
I will report back on how the ceiling looks after painting.

Today’s test coat revealed the following: carefully aligning the strips is absolutely pointless. It’s best to leave a tiny gap between each strip. The paint flows in and then looks excellent.
Tomorrow, we need to cut small gaps in some places where we applied the strips particularly well and neatly, because now the joints are visible there. Unfortunate, but easily fixable.

What now? I thought you should always wallpaper edge to edge, without overlapping or leaving a gap.
How is paint supposed to run onto the ceiling?
Maybe on the wall that might work...
