Boy o boy... I've spent the entire morning sanding the ceiling of my daughters room. After the isolation had been placed, I started putting plasterboards to the ceiling. The gaps have been plastered a first time afterwards. This has to be sanded to create a smooth surface...

Unfortunately the whole operation is... well... I had plaster dust all over me. When I showered the water flowed down my legs all white. Well... next step will be to apply a second layer of plastering to make it even more smooth.

I fear that cleaning the whole mess up will be difficult, too. The stuff is quite volatile and flies up whenever you make a movement.
