Old sins tend to catch up.
I have a slab on the ground where only styrofoam is exposed to the outside world, it was protected by black plastic, but it's starting to give in.
I'm thinking of attaching a baseboard to the styrofoam and would like to screw it in with stainless screws, but readily available are only 60 mm long screws. Sifverts screws have up to 100 mm but with a 6-week delivery time and you probably have to buy a pack of 100, and I need about 10.
The styrofoam is 50 mm thick + the board + the screw should also sit in the concrete with a plug, so it should be at least 80 mm long.
Anyone have an idea where I can find the screws or another way to attach the board?
