I have an older season cabin which currently has drywall ceilings. This cabin is not heated in the winter, so the drywall seams have cracked. In addition, it is older drywall and is brittle in some spots. (Found this when I went to patch a hole from an ambitious squirrel.) Looking for the best option to solve for this issue. Thinking it is best to cover it up vs trying to remove. Anyone have any recommendations regarding the best material for his project? Looking to do this in an inexpensive manner if possible. Thanks.
