Hello forum,

Our building features precast concrete ceilings. The ceilings are to be primed with a deep-penetrating primer and then the joints will be filled with a joint filler, sanded smooth afterward. After that, both ceilings and walls are planned to be covered with painter’s fleece wallpaper.

Is it sufficient to fill only the joints, or does the entire ceiling need to be filled?

Best regards,
schoermi

Only the joints were filled with joint compound here, and it looks good.

Best regards

Everything was plastered here, even with two layers, and then sanded. However, our precast concrete ceilings had some cracks and were partially a bit uneven. The plasterer inspected them and advised us accordingly. He wouldn’t have just filled the joints and then painted the ceilings.
