Attaching kitchen fittings to aerated concrete...?

[Peppermannen]

Hello,
I have torn out my kitchen and am going to install a new one. From the inside, it had masonite-tretex-scattered boards (air gap? see picture)-paper-blue concrete (light concrete). Now to the question: What should I put up to attach the cabinets to, and how should this be attached to the porous blue concrete? Does there need to be an air gap against the blue concrete? Tips are very gratefully received... :S

No one answered... Oh well, I've solved it and thought I'd share. I put up the "pappa" on the wall and then put up the framework with sparse 28x70mm which I secured with 100mm nail plugs. Between the nail plugs, I also secured with 6-inch nails which I nailed in-knocked at an angle-nailed in-knocked at an angle, etc. Apparently, it's a technique that makes the nails bend slightly into the wall and thus hold better.

That sounds solid. Thanks for sharing.

Unfortunately, it's too late for you, I didn't see your question when you started the thread, but I installed our kitchen fixtures with Fischer plugs in the blue concrete and French screws. They've been in place since 2003 now. Your method seems to be an old one, as it was done when there were no plugs available. That's how the old fixtures were mounted in our house (although with just nails, of course, no nail plugs), they had been up from 1964 to 2003 and everything held like hell So it certainly works, maybe even better than plugs and screws?

Have used the method... It works best with a so-called klippspik. We used to compete in getting the nail out on the same side it was hammered in.
Of course, with a marking where we thought it would come out.
Closest wins.

Best regards/Findus

There are different types of plugs specifically for lightweight concrete that work excellently for the purpose as well. For example, Fischer GB: http://www.fischersverige.se/Portal...n_infastning/_dokument/Lattbetongplugg_GB.pdf Gunnebo KBT: http://www.gunneboindustries.com/sv...er/Expander--Plugg/Plugg/Lattbetongplugg-KBT/

I have tried both with very good results, and they are not particularly expensive in this context.

The super expensive alternative is HEMA-nails: http://www.beijerbygg.se/templates/BB_Produkt.aspx?id=2982 I haven't tried these but they look like they could work well too

Threaded rod + anchoring compound is also a viable option. Clip nails hold very well and work too

Nail plugs in lightweight concrete I have only had bad experiences with, so I would avoid them.

Unfortunately, I seem to have completely missed this thread...

I only have bad experience with nail plugs in lightweight concrete/blåbetong, but there are special screws for lightweight concrete that work well...

I have just attached a handrail to aerated concrete beams, which became very stable and good. I used a special screw from ESSVE called "Lättbetongskruv 8x130" which threads directly into the aerated concrete without any pre-drilling. It basically looks like a very coarse wood screw. More can be read at: http://www.essve.com/se/Retail/Pressrum/?nditemId=222075&type=pressrelease

Otherwise, I have used Fischer plugs, but this was much better. Highly recommended.

Exactly what I was referring to in the previous post... d^_^b

There are similar ones for concrete that are really good as well, but there you have to pre-drill...
