Hello,

I need to install some cable trims in our habitable basement to hide some lamp cords.

The first question is, can I screw these directly onto the wall with the foam tape strip still on?

Or should I remove it from all the trims due to possible moisture from the silicate-painted walls?

I can mention that I have previously taped trims on the walls, and they hold well but not well enough to allow opening and closing them twice a year when the Christmas star appears.

The floor in the basement is of the ventilated type without an active fan. I know this is a risk construction, but that's not the question. In this case, I would like to place the cable trims under the radiator pipes to follow them, which means that the ventilation here will suffer.

The trim is 16 mm and the gap is 19 mm, which gives a 3 mm clearance down to the floor trim. Here you can see the clearance:

However, the trim will rest against the radiator pipe holder and not the floor trim to still maintain some ventilation.

Looking from above, the floor trims are positioned away from the wall in the following way:

Here's another example of how trims and ventilation work:

My estimate is that cable trims will be needed that extend just over halfway across the room.

The last question is how much heat can cords and cable trims withstand? We can have a supply heat of up to 80 degrees when it's really cold outside. Is there a risk of melting the plastic or for that matter the cable, which is partially cloth-covered?
 
I find it hard to see that you wouldn't be able to keep the tape.

A supply temperature of 80 degrees sounds extreme. Why such a high temperature?
The plastic moldings probably won't like it long-term.
