Anchor adhesive for beginners?

[lars_stefan_axelsson]

This is actually not true. The anchor mass is of a two-component type that mixes in the nozzle, so it's possible to use the tube multiple times, but with a new nozzle.

Yep! That's how it should be. But I haven't succeeded so far. So I recommend seeing it as a bonus and planning for single use.

Now I always buy the cheapest one I can find. Those of you who spend more may very well have other, better, experiences.

Ok so the same solution as the others? Biltema's costs 99 vs several hundred for the competitors, so if you say it works, I'll try it with that.

When it comes to cleaning, it's boring to spend a couple of hundred bucks on a brush and a blower gadget. It must work with any narrow brush, and blowing with a straw? Or that won't work well?

Yep. Biltema works. And as long as you've blown/scrubbed the hole well, it's enough. You can blow by hand with a straw if you want to. You can also scrub with a wooden stick in the worst case, it depends on how good your concrete is.

I have used Fischer VL, works well to use the cartridge multiple times by changing the nozzle.

If the OP is concerned about durability, I think he should skip considerations about Biltema and what shortcuts can be taken in the installation. I maintain that a standard expansion bolt will handle the load in question with plenty of margin. I assume it's a question of a floor structure, so the concrete can't possibly be that poor. And if it were, anchor compound wouldn’t help much. By all means, take a through-bolt and a large washer on the top side. Simple, cheap, and vastly superior in terms of durability.

If the OP is worried about the durability, I think he should skip the considerations about Biltema and what shortcuts one can take in the installation. I maintain that a regular expansion bolt with a wide margin can handle the load in question here. I assume it's a question of a joist system, and then the concrete can reasonably not be that poor. And if it is, anchor mass won't help much. By all means, use through holes and a large washer on top. Simple, cheap, and superior in terms of strength.

haha yes, a washer on the living room floor would feel the safest!

I have to say that I have zero understanding of the construction, how did they build a basement ceiling in 1947? Do they build a temporary wooden roof, put in rebar and pour in concrete, then remove the wood once it's hardened? Or in a completely different way?
