Poroton and speaker cables

Hello everyone, we are building with Poroton bricks and I was thinking about running speaker cables inside the living room wall to connect a surround system (if there is money left). After seeing how easily these bricks break at the electricians, the question is: Can I fix the thin speaker cables with plaster and stick them directly onto the Poroton???

I don’t know how thick the interior plaster will be, but speaker cables are not particularly large in diameter.

Hello Bluebyte,

that should work in my opinion. An interior plaster is usually at least 10 to 12mm thick. If you get gypsum plaster, then get a pinch of it beforehand and fix it right away with the original material. That way, there are no different materials and also no - if certainly only small - tensions between plaster and fixing. If you can, go into Excel and document your cables.

Cutting grooves in Poroton is a very critical matter if you damage the cavities in the process. With the thin wall thicknesses used nowadays, every centimeter counts in my opinion.
