Hello everyone, we moved in in the middle of last year and have a steel staircase with wooden steps. The wooden steps were only glued at the time. Now we have the problem that since we moved in, two steps have come loose. The carpenter used Lugato bombenfest as adhesive, a type of assembly adhesive. Can you recommend something better?
The steps have been oiled twice and the glued area was not scored or treated in any way. (We had noticed this with the first step.)
After the first step came loose, we reglued it. The second step is not completely detached yet but already loose. The adhesive sticks to the steel but not to the wood. What would you recommend now? I have attached pictures of the staircase construction. Of course, it is possible to screw the steps in place. However, we did not want to see screws from underneath. If we decide to screw them in now, is it possible to drill from below while keeping the steps in place?

That was the question from the OP — asking for possible solutions — not about the effort involved... 😉I wonder who designs, manufactures, and sells something like this? A design as useful as a chocolate hammer,...Myrna_Loy schrieb:
Yes, you can try solutions like that. But in the end, it’s just fiddling around with a lot of effort to achieve a design. Oh, effort is no big deal. It’s a one-time thing, and then hopefully the staircase will last 20 years.
So I’m really open to any suggestions.
I have now cleaned the steel and sanded the step. It was surprisingly quick for the wood to become lighter. I’m going to score the area with a utility knife and then reattach it.
I think this will temporarily fix it quickly, but the underlying problem remains. :/
Maybe the adhesive is just not well suited. It’s like a type of silicone and can easily be sanded off from both the steel and the wood.
Of course, that happens with any glue, but this one seems to come off quite quickly and easily when sanded.

Unlike screws, the wood structure is not excessively stressed, allowing the wood to expand and contract naturally. So: hole -> sleeve -> screw (in the color of the metal) from below. Form follows function!
