I am currently converting a large stone built barn in southern France.I wish to insulate the exterior walls with a plasterboard finish. As the barn is so big I was hoping to get away with using the dot and dab method to cover the walls.
in general the barn is dry and in good condition,with no signs of damp.
1. do I need to treat the walls in any way
2. will it work
3. what type of insulated plasterboard can I use for this method.
4. Is there an easier/quicker way-these walls are vast![/code]
