I need tips on how to fix a gap that has appeared in my apartment between the parquet floor and the wall. This is due to settling. The gap is about 6-7 cm. I'm thinking of trimming the parquet so that it becomes straight and even. Then lay an oak plank/molding perpendicular to the parquet and then the floor trim on top. I was thinking of sealing with a sealing tape between the brick wall and the floor.
But how do I attach the additional plank to the existing floor?? And I need to raise it about 2 cm?? (The parquet is about 20mm thick).
What I think will look best is a wide molding and a quarter round at the bottom to cover the gap. Remember the quarter round should be screwed into the molding and not into the floor so the wooden floor can move freely underneath. You can glue the molding up under tension with regular PL 400. It holds strong. Ensure the surface is even beforehand.
If I understand you correctly, the strip will become very thick, right? Here is the original strip I will reuse, it is about 1.5cm thick. The gap is 6-7 cm... Or have I misunderstood you?
The trim will be quite thick. With that particular trim, it will look strange with a quarterboard at the bottom. There are many ways to do it. The least troublesome way is as you suggested, with a horizontal board underneath and then the trim on top. If you want it perfect, a new floor is required. The alternative is a cast base as before or to smooth plaster the walls until a trim covers well. A plastered base doesn't have to be square and ugly. You can bevel it slightly so it doesn't look like a block at the bottom.
If you follow my suggestion, how would you get the horizontal plank at the right height with the parquet and how is it anchored?
I can build up the skirting along the wall but not all the way out to the parquet. Then it won't have any support from the bricks. Then gluing the plank to the parquet is probably a bad idea considering it needs to be able to move..?
You can screw the board into the floor if you leave a movement margin. Wood moves about 1 mm per meter. Then you can let the trim run freely. It's the easiest. Few attachment points with flexible sealant, and there are no problems.
The alternative with the baseboard is to plaster it out to let the trim cover the last bit.
