Hello!
We won't have insulation; instead, we'll have bare walls, and the floor will have tiles throughout the house. That's how we want it. It's a concrete slab, and the walls are hollow bricks with concrete and then plaster as I understand it.
Now to my questions.
1. We want to make the area around the windows look nice and touch up the edges. What kind of filler should we use for that?
2. What should we use to fill in the holes in the walls?
3. There are open grooves on the side where the floor meets the wall, as well as 2 other grooves that run straight through the room. What should we use to fill them in?
/Inexperienced but happy to take all tips and advice we can get
