The ceiling on the ground floor is planned to be made of precast reinforced concrete elements. Since this leaves a groove, it will need to be filled with filler.

The developer suggested that I should leave this to a professional. 😕 Is it really that difficult to fill this groove? Although I mostly work in an office, I have done filling work before, albeit on drywall, but it shouldn’t be that much different, right?

Hello Cmajere!!

I would say that if you have already worked with drywall (gypsum board) joint compound, dealing with the concrete ceiling (joints) shouldn’t be too difficult. The only thing to keep in mind is that the material you use for filling should be flexible because of movement.

Also, how does the underside of the concrete ceiling look? Will it be coated as well, or finished with drywall, wood, etc.?

If you decide to do it yourself, I’d be happy to share a few more tips with you.

Best regards.

Hello,

I suppose the underside will be concrete gray with porous air holes. I will probably use a thick paint to cover the holes (hope that works) or textured paint, but maybe you have a tip for me on how to get rid of these holes.

Hello!!

Well, the issue with the holes is a bit tricky because it’s hard to know where to start and stop *lol*. You can certainly cover them with paint, but then you might have to apply several layers, which can take some time.

For me, there are basically only two solutions: either skim coat the entire ceiling with a thin layer of plaster or install drywall panels.

Skim coating definitely requires a professional, as it takes some skill.

With drywall, the advantage is that you can hide certain things, such as electrical cables (and you don’t need to chisel out too much). This also applies to ceiling lighting like LED spots or regular lights and so on.

Unfortunately, I don’t know how your contract is worded or how much work you plan to do yourself.

Best regards.

Hello everyone,

So, Cmajere, if you have successfully finished drywall before, you should be able to finish the ceiling as well. It’s not that difficult, just overhead. Make sure to remove any concrete spill-overs first.

You need to apply joint compound to the seams 1 to 2 times, but (important) not beyond the seams, otherwise you’ll get bulges. For smoothing, you’ll need a very wide putty knife.

Some larger pores and minor shrinkage cracks cannot be covered with paint alone. So you have to either plaster the entire surface or wallpaper.

If downlights are planned in the ceiling, usually the precast concrete panels have openings left at the appropriate spots, through which the electrician can pull the necessary cables. The electrical wiring is laid on the precast panels and then embedded in the cast-in-place concrete topping.

If these are what I assume to be precast concrete slabs, you can skip fully skimming the surface if you plan to apply wallpaper, provided the ceiling surface is flat and smooth.
