Hello!
A few years ago, we fixed up a room in the basement (split-level house). We drained the house a couple of years before, so the plastered walls were really dry and nice. I placed studs on the walls to act as an air gap and on these, OSB+gypsum. The floor is concrete, where I put a Platon sheet to get a bit of air gap and then laminate flooring on top. One wall towards the direction where the ground is lower than the outer wall, as well as a ceiling that extends 4 meters from the wall, I didn't put an air gap; the wall surface is only 2.5 m2. I consider it to be a really dry wall.
I've occasionally noticed a slight smell from the room, hard to distinguish from the dog's scent and maybe a faint mold smell. The dog mostly lives in this room. The ventilation isn't great in the room, but the door often stands open to the room.
Do you have any hypotheses? My thought is that some liquid/dog pee etc. has spilled on the Platon sheet and is fermenting
Or that it's just the dog's smell. I can add that once a large stuffed animal had been placed against a wall and isolated it against the heat in the room. Behind it, a mold spot had formed on the wallpaper, which could be easily wiped off. Could this mean that it's humid air?
The person living in the room will soon move out, so I will clean and air it out thoroughly, and then we'll see if it disappears, but if not, then it's probably mold... Grateful for ideas.
