Edge finish for vinyl flooring

Hello,

we have newly built. The cement screed was treated with leveling compound and primer, and then adhesive vinyl was laid on top. The order was: we do not want the usual edge profiles/skirtings, but strips should be cut from the vinyl to be glued to the wall as edge profiles. The wall connection was realized with a very fine joint, about 5mm wide. It really looked good.
Now all joints had to be reopened because the vinyl probably did not adhere properly and/or expanded too much. Be that as it may, that is another topic why this happened. Also, some planks in the middle of the room were hollow; the company has already re-glued them and wants to close the joints again in a year. "Of course," the manually cut-open joints look simply awful at the moment and became wider when cut open than the previously neatly applied silicone joint. Now a few questions arise which I hope someone can answer me to know whether I can apply some pressure:

- Since I have already seen this type of skirting in various medical practices – can I assume that it is generally feasible in the private sector as well to use the vinyl itself as an edge finish instead of these usual much too wide baseboards?

- How much edge clearance should reasonably be maintained between glued vinyl and the wall to prevent consequential damage due to expansion?

- If in our case a silicone joint is applied all around, how much overlap should it have on the vinyl to hold properly and not tear immediately? That is, how many millimeters should the silicone joint on the floor – it is a triangular joint – be wider than the joint to be covered?

We consciously chose the vinyl strips because we believe the "normal" baseboards are just dust collectors. We were fine with the initial silicone joint, but since the company does not want to repair the partially roughly cut edges with new planks for economic reasons, the new joints will be wider (it must also look uniform). When I look more closely at the old joints, it can occasionally be seen that the silicone initially covered the vinyl by at least 3mm. So if I add 3mm to the cut-out joint, the new silicone joint will be at least 8mm wide, occasionally up to 1cm. Can I veto this and demand rework?

Weren't you warned about this method during the new construction? Is the subfloor, screed really dry enough for something like this? The planks coming up could have something to do with moisture. You want to seal everything hermetically. Vinyl, also glued to the wall, joint with sealant, nowhere can anything escape. I consider the whole project quite risky. Please leave the joint open for a few months now. Karsten

Whether vinyl or tile: the screed settles during the drying year and shrinks. Downwards.
Therefore, the silicone joints between the covering and the skirting board definitely need to be renewed after 1-2 years.
Those who are wise wait and live with the open gap in the meantime.
Everyone else lives with the fact that it has to be replaced faster than they have gotten used to it.

I thought raised flooring as a wall finish hasn't existed since the 90s...

It's not pulled up; rather straps made of vinyl; like with tiles

No, I was not warned beforehand, but that is not the problem either, because the company basically acknowledges the warranty for it and wants to renew the joint. My problem is that due to the sloppy removal of the old joint, the new joint grows from 5mm to 8-10mm, thus partially becoming twice as wide as before, because for "economic reasons" the edge areas are not to be replaced by new planks. And I wanted to know if anyone can contribute anything to this, whether there is a point of attack on my part that I can insist on complete repair or if I then have to "swallow" it like that?
