I have purchased a 200year old Cob cottage in Exeter which I am restoring. The cob is still in reasonable condition. The interior walls of the house have been skimed in a layer of gypsum plaster to give a sheem finish. I was advised that it will be difficult to scrape off the gypsom layer and will create more damage to the cob. Uunfortunately this was done many years ago and is starting to come off in a few placees. How can I best finish the walls? thanks
