Fill milling grooves with house fix?

[Trattkantarell]

We have routed for cable conduit in several places in our walls and are now going to start filling them in. We bought house fix after a tip but wonder how best to prep for it to hold. How much margin should there be between the cable conduit and the surface layer for it to hold? Do you need to apply primer to the cable conduit? Will it hold without applying microfibre fabric on top as a barrier layer? Of course, you can always try it out, but the last thing you want is for pieces of the wall to fall out after you've painted...

I plastered with gypsum mortar I recall, I think I was satisfied that I didn't see the hoses.
Then I put microlit on top.

Saw nothing during the four years we had the apartment.

Edit: reading poorly, didn't prime, just wet where I was going to plaster.
Recommend microlit because otherwise you'll get craters if you try to put something up.

The most important thing is to apply the husfix deeply. It should not only adhere to the hose.

And don't apply the filler too high, husfix is difficult to sand. Instead, finish with regular filler.

The most important thing is to get the husfix in deep. It shouldn't just stick to the pipe.

And don't sand too high, husfix is difficult to sand. Instead, finish with regular filler.

Thanks for the quick reply.
So you mean it should bind around the pipe as well? We have a groove where a double pipe is supposed to go, which is a bit problematic because it’s super tight and there’s no gap between the pipe and the side of the milling groove. I personally think it smells like trouble but haven't gotten much support from my partner on this...

I used gypsum plaster, if I recall correctly, and I was satisfied as long as I couldn't see the pipes.
Then I put microlit on top.

Saw nothing during the four years we had the apartment.

Edit: reading like a rake, didn't prime, just wetted where I was going to plaster.
I recommend microlit, otherwise, you'll get craters if you try to mount something.

Considering putting microlit on the wall where the TV and possibly the TV bench will be mounted. Do you buy it in rolls? Should seams be edge to edge in that case? Buy at a hardware store or paint store?

 

[13th Marine]

I bought mine on a 50m roll, 1m wide. Edge to edge.

I have bought both at the paint and hardware store, take where the price is best. First, I bought pre-primed, but it was exactly the same installation procedure on both and you had to paint the same number of layers.

The optimal approach is probably to apply some filler at the bottom of the groove, then press the hose in place and level the filler with the surface.

Protte

Thanks for the quick response.
So you mean it should wrap around the hose as well? We have a groove where double hose is supposed to lie, which is a bit problematic because it's super tight and there's no space between the hose and the side of the milling groove. I myself think it smells like trouble but haven't gotten much support from my partner on this...

You can usually lift the hose a bit and poke it in, or press a little with the putty knife. It will stick to the hose as well. But remember you don't want a lot of air behind the adhesive.

Empty cartridge like a latex sealant cartridge that you fill with Casco Kombirapid. Inject from the bottom up generously and smooth with a spatula. Refill manually like typical spackling. The Kombirapid can be smoothed with a sponge just like tile grout.

Husfix is a scourge!
Gypsum plaster saves you here as someone else also wrote.
I usually squeeze in a few clicks with Tec7 and insert the hose, when it's dry I then go on with gypsum plaster. Webers Gypsum I can highly recommend.

and are now starting to fill these in.

Why buy expensive things when there are cheap ones, bring out the flower spray, wet thoroughly in the grooves and around the boxes (fill the boxes with newspaper) wait a few hours and use regular plaster (throw/cast into the grooves/around the boxes) scrape a little so the plaster is just below the wall surface and then fill with filler.

 

[jonaserik]

PS Remove all devices from the boxes otherwise a lot of dirt will get into the devices and a replacement must take place, it's impossible to get them to work after plastering in them.

I've done that a lot, and as people say, use Gipsbruk. I've used various brands, and byggmax worked just as well, so don't buy anything expensive. Make it a bit wet and throw it in, use two wide putty knives. Then spread it evenly. It will shrink, so apply it once more, then putty. I've never needed soaking despite doing about 100 meters without microlit, nothing shows and nothing has cracked. I've used it on blue concrete, brick, and cast concrete, with the same result.
