We bought an apartment from the 1940s and are working on our first renovation project, sprucing up the bedroom. We started by scraping off old wallpaper, which turned out to be about 4-5 layers of wallpaper with a bit of paint and filler in between, almost 5 mm thick. Now we have bare walls made of what I guess is some sort of lightweight concrete (image 1). There are quite a few deep holes & cracks in it (image 2). We haven't done much to the ceiling. The floor consists of at least two layers of parquet, the newer one on top of the old with a cover strip (image 3 and 4 from the living room, where only the old parquet is present). The old trim & door casing is quite damaged & worn and there's some kind of rubber sealing strip on top (image 5). I apologize for my amateur description & lack of knowledge. I would greatly appreciate any tips & advice regarding our renovation plans, which we have mostly put together from reading this forum:
1, Walls – First, fill the holes with gypsum plaster or household fix. Then sand the entire wall using a wall sander/giraffe with coarser sandpaper (80 or 40) to remove wallpaper remnants & larger uneven surfaces. Apply a wide spackle with coarse filler, sand with a wall sander (120). If still not completely smooth, spackle one more time with fine filler, sand again, then paint.
2, Trim & floor – The old trims are very difficult to remove and are even tucked behind (not under) the newer parquet, so we intend to leave them and instead try to sand & paint them. The same goes for the door casing. Is there anything particular to consider here? Is it important to remove all old paint, or is thorough sanding & two layers of carpenter's paint sufficient? Do you do this before or after painting the walls? I've also considered running an electrical cable behind the trim to get an extra outlet on a wall that has no sockets.
3, Electrical – There are too few outlets in the apartment, and the extra ones installed have very unsightly cables running on the outside. For example, there is an outlet in the dining room that is on the wall adjacent to the bedroom (image 6). On the other side of the same wall is the switch for the bedroom (image 7). According to the electrician, it should be possible to run electricity down from the switch’s box and through the wall. I am considering routing a channel to the height of the outlets and there recessing holes for two boxes back-to-back, thus replacing the unsightly outlet and creating an extra one in the bedroom. I plan to insert a 16 mm flexible conduit from the switch box and then place two ROT boxes back-to-back. I wonder if there's anything specific to consider here? How would you connect the ROT boxes most effectively (the wall is about 90 mm thick)? Would it also be possible to route further down to the trim and run a cable behind it to the next wall where there is no socket or outlet, according to point 2?
Sorry for the complicated description, hope the images explain something.
