Installing the skirting boards are not as simple as one might assume, as they can have a play a great part of the soundproofing concept. See how I manage this. I go into details of how to mount the skirtings to keep the floor isolated from the walls, while maintaining enough pressure to keep the laminated floorboards in place.
Also installed and painted is the second internal door, to complete the build of the project. All left is the door sealing and the acoustics between the two doors.
