Hello. New here 
I wallpapered my mother-in-law's apartment hall, and she wanted to change the ceiling and floor moldings too. The apartment walls are concrete.
The old ceiling moldings had been nailed with those white clip nails, so I got a box of them and just decided to test nailing one since I had never used them before. I bent them every time. I don’t understand how they managed it with the old moldings.
Is it a load-bearing wall then and not lightweight concrete there? I tried the same thing down by the floor and bent it too. Then I tested on two of the other walls by the floor, and it went fine.
So what can I do? I probably don’t want to drill and mess with screw plugs since the moldings are white Allmoge pine 56mm. It probably won't look good with that.
But how did they use those clip nails in the past? Pre-drilled small holes? It seems to only work in lightweight concrete.
At Woody, they said that was what I should use. They didn’t have any smaller steel brads, which I thought I needed. Can I find that at Jem & Fix maybe? Ones that set in real concrete.
I’m not sure if I want to try gluing.
Hope someone answers something

I would still choose to use white-painted nail plugs in this case as it's quicker and easier to install and you don't need to paint afterward.
If you still want to try nailing into the concrete, I can recommend hammer nails if it's really hard concrete, otherwise, regular steel nails work fine (you can, for example, use nails from regular cable clips).

If you have "real" concrete, I would forget all about nails. Drilling, screw plugs, and white screws should look good enough. Or as mentioned, white nail plugs might be quicker but could look a bit bulkier. It somewhat depends on personal taste what you choose.Baeckz said:
Ok, But is it just this concrete on that particular wall? That it's load-bearing. Since it worked fine to nail the clout nails in the others. In that case, maybe I just need to use nail plugs on the harder wall.
Should have had those nail plugs with a countersunk collar in that case. But what dimensions are we talking about that I should have at a minimum?
And as I said, then I need a hammer drill?
