Hi,
I'm going to take the opportunity to cut a channel for the electrician to pull some wiring while we're renovating a room. Uncertain about the exact material in the wall, but it's not drywall or concrete (see picture).

What tool should I aim to use to make it as smooth as possible?
 
  • A hole in a wall showing electrical wiring and insulation material, questioning which tool to use for cutting a channel for wiring installation.
Looks like Tretex, probably can't really be traced in without the sheets turning into waste.
 
Tear down the boards, install new electrical wiring, and then put up OSB + Gypsum. That way, you'll also have walls that can hold things up.

Check what you have behind the tretex. Route out or track with a circular saw. Pull in VPR pipes. Gypsum on top if you have spontaneous behind.
 
congratulations, treetex is a hell. I don't have much advice to offer unfortunately, the boards are a bit like working with a damp cracker. Everything splinters very easily and it is very difficult to get nice edges. Maybe try cutting with a really sharp knife first and then a fine-toothed jigsaw...

I've done it, and it went really well. I guess ts should just try it before getting advice to tear it down??

How did you do it? It's a small room and I have no desire to start a project tearing out and putting up new panels. So I'd gladly take any tips on how I can handle the wall to create a channel.

Worked well for me too. Used a multimachine though.

I used a circular saw and cut through. I didn't have access to a multicutter then.
 
Drew it up first.

A multicutter will cut through the tretex like butter :-)

What's behind it, plank frame? Then keep in mind that you weaken the construction if you start routing crosswise.
 
Used an electric chainsaw and set a stop with a clamp so as not to cut too deep, then you can cut both tretex and wood but I assume you plan to plaster over it later.
 
Here's how I did it...

Removed all Tretex, drilled a hole with the hole saw, and routed with a hand router:

Then I grooved with an electric chainsaw:

Then I could screw in the boxes and pull the conduit before reinforcing with screws and plastering:

As mgranbom, and even p-plats showed with pictures here in the thread, tear down the treetex first, then route in pipes and boxes and cover with gypsum, possibly OSB+gypsum.

But if you like listening to music, a bit more or less audiophile, it can be unfortunate to remove the treetex, as it usually results in very pleasant acoustics in rooms (houses) with plank or wood frame and treetex. It provides a bit of natural damping. I've lived in such a house myself, and I've never had better room acoustics, without additional measures, than there.

However, after all, the simplest way with the most guaranteed result is probably to remove the treetex and apply gypsum when all the electrical work is done.

In my dwelling, which I just wrote about, we brought in some extra electricity.
I routed right through the treetex and into the plank walls about 20-25mm deep. I attached VP pipes and finished by troweling over smoothly and then applied new wallpaper.
It worked for the few years I stayed there, but I suspect it may have started to crack later because troweling against treetex doesn't seem like a particularly stable construction.
If I were to do this today (but probably wouldn't) I would likely try to smooth trowel just in the routed area at first, let it dry, then glue paper tape over with fabric and wallpaper adhesive, and finish with a bit of broad troweling over the tape to ensure it doesn't show after the surface layer is in place.

Though tearing off treetex is quite a tough job too, since it's so difficult to remove it in large pieces... so whether it's the easiest I would say is questionable, but the best result is probably true.
