Having moved house about 2 months ago, the brick garage with a flat roof looked like being an improvement on the 10 x 8 shed at the old house.
Now any of my big lumps of cast iron are frequently wringing wet with condensation and any bare metal parts such as flywheel rims and lathe or milling machine beds are rusting before my eyes.
Does anyone have any ideas on how to stop this. I am thinking about lining the roof and walls with plasterboard or plywood and filling the cavity between the board and brick wall with rockwool type insulation. Has anyone else tried this and found it successful, also any ideas on a long term background type of heating that can be left on at night for most of the winter without it costing a fortune.
I know that I can coat everything in oil or grease until the spring but this not always convenient when I want to nip in to the workshop and use the lathe, when I get an hour to spare I don't want to spend 20 minutes cleaning the grease off before I start and the same again reapplying before I can go back in the house.
Many thanks - Paul.
