To begin with everything needed stripping out of the box. There was lots of metal trunking, electric hook up points, battery chargers, strip lights, sockets etc that all came out. Once the box was empty I decided that the paint (which was old and flaking off) needed to be striped off. A nasty job that I soon draughted Cally in to help with, paint stripper really burns! I made the wrong choice of protective clothing and soon realised that I'd have to put something over my vest. Finally I gave the walls a quick sanding down so they'd be ready for the insulation to be glued up.
