New bottom in trash cabinet?

[Rolle85]

I have an integrated garbage cabinet in the house as was done in the 90s. The floor is now seriously rusted and almost through. Can one fill the floor with something to secure it? It might be about 1m2.

Road salt is probably a significant contributing factor.
What is the material under the cabinet?

 

[Rolle85]

Asphalt

Anyone?
Pondering epoxy or self-leveling compound?

 

[Unikt namn]

Doubtful how well self-leveling compound adheres to metal?

I would primarily have torn out the cabinet.
Secondly, laid a rubber/plastic mat at the bottom.

They have kind of rusted through so I need to stop it.

Is there any epoxy?

The best thing is probably to replace the cabinet with something better suited to today's demands and needs. Possibly, the door can be retained if it fits better aesthetically.

Without having seen it in person, I would still guess that it can't be stopped.

Possibly you can hide the rust for a while. But it will likely return. The entire underside will continue to rust if not addressed.

If there is asphalt underneath, I suggest cutting away the bottom of the cabinet and placing the contents on the asphalt.

If there is gravel underneath instead, I would have probably cut away the bottom and laid paving stones/tiles/brick as flooring.

I would prefer to protect the steel/iron sheet walls with 2-component polyurethane lacquer (the same used for painting cars) as I find it more flexible than epoxy lacquer and thus more suitable (epoxy is better for laminating).

can you buy epoxy at biltema or similar
hornbach?

Remove what is rusty, make a template in cardboard, the sheet metal shop will cut a vfz sheet.

Looks like it's used as storage. Cut off the metal piece at the bottom and lay on whatever you think fits.

You have moisture from underneath, so to stop it you need to get under the metal. It's significantly easier and cheaper to remove the metal completely. If you want metal at the bottom, then buy a stainless (rust-resistant) one and attach it appropriately. Otherwise, asphalt might work as a floor, right?
Walls, doors, etc. you can brush clean, cold-galvanize, and then potentially decide on a method for further protection. Cold galvanizing has the advantage that it's just a matter of applying a new layer if/when rust appears again.
If you're considering painting the outside, you can skip galvanizing it since the primer is supposed to perform the same function.
