Hi!
I'm going to mount wooden battens in the ceiling, 45x45 and 386 cm long.
The question is whether 5 nail plugs (6x10mm) per batten are enough?
With nail plugs 10 cm in from each end, it's about 90 cm between the three nails in the middle.
I initially thought of using 6 nail plugs per batten, but since I want to place one in the middle to ease the installation, my alternative is 7, which means a lot more drilling into the concrete...
I will have only one layer of drywall on the battens (12.5 mm).
Grateful for a response!

1. The studs should be placed 300mm center-to-center in relation to each other, but I'm sure you're already aware of that.
2. To drill into concrete, you should use a rotary hammer drill; a regular hammer drill is a waste of your time and effort. There are cheap ones available starting from around 500-SEK and up.
3. Now for the little trick: with the right type of bit, you can use the rotary hammer to drill through both the wooden stud and the concrete. I have used Pirhana bits, even though some here on the forum scoff at Pirhana. You should drill with one size, spend a few extra bucks on a branded bit.
4. Regarding the nail anchor, buy a proper nail anchor at Beijers or any other expensive construction store, where you know you're only being overcharged on price and not on quality. Nail anchors from Byggmax and Biltema have (as of 2 years ago) plastic that is too soft and get stuck before you've driven them in. When done correctly, it's super easy with a nail, just drill a suitable hole, insert the anchor, and hit it with a hammer!
Edit.
5. Since there are no problems with drilling now, I think you should set the nail anchors at ~600mm center-to-center, provided that you can see the anchor bites into the concrete; otherwise, you will need to place them closer.

Ok thanks for the tips!magnu said:1. The studs should (must) be placed 300mm center-to-center in relation to each other, but you probably already know that.
It will be 6 studs per 250-panel. So about 400mm center-to-center. It will work fine
2. To drill into the concrete you should use a hammer drill, a regular drill is a waste of your time and energy, there are cheap ones from around 500 SEK and up.
I have a hammer drill, one from coop about 500 SEK, works great.
3. Now to the little trick, with the right type of drill bit, you can use the hammer drill to drill through both the wooden stud and the concrete. I've used Pirhana bits, even though some here on the forum scoff at Pirhana. You should drill with one dimension, spend a few kronor on a branded bit.
Even if I drill through the wood and the concrete with the same bit, the wooden stud must first be mounted to the ceiling, or alternatively supported from below in some way?
I have a regular drill for drilling into the wood. Switching drills between wood and concrete doesn't seem like a major problem, right?
4. Regarding the nail plug, buy real nail plug, at Beijers or some other expensive construction store, where you know you're just being tricked on price and not quality. The nail plugs from Byggmax and Biltema have (2 years ago) too soft plastic and get stuck before you've hammered them in.
When done right, it's super easy with spikes, drill a proper hole, insert the plug, and hammer it in!
Already bought nail plugs at Byggmax :blushing:

5. Since there's now no problem drilling, I think you should set the nail plugs at ~600mm center-to-center, provided you see the plug bites into the concrete, otherwise you need to set them closer.
I would recommend so-called guldhylsor or fjäderspik. They come in different versions, but the one I think is the best by far is the ones that look like a tube with a slit and collar on them. No problem to hammer in, and you avoid all the hassle with plastic plugs, etc.
