Single story ranch with truss construction as in diagram.
Living room/ dining room is L-shaped 16 X 33. Trusses span the entire 33' length (edited this last sentence)
When we moved in 9 years ago the ceiling had a crack that transversed the 16' width that is directly under the plates where the truss members meet.
47473
I cleaned out the crack and retaped. Repair lasted a year. We had 5" of snow, then ice, then another 14" of snow in 48 hours that winter. Crack came back. I have lived with this for last few years, but it has bugged me. We are repainting the room this month and would like to repair it permanently. But I must be realistic. We have those kind of snows if not at least once every winter, then certainly every two or three winters.
This is what I am thinking:
Cut out a 2 foot section along the crack and replace the drywall so there are no joints (still have the single butt joint) under the place where the truss members meet. But I say to myself, "But I am sure the original sheetrock people did not have a 16 foot joint right there originally, so it probably cracked the drywall. So, would it happen again?"
I have heard there are some new and improved joint compound stuff that is elastic-like. I have not been able to find such products on the internet, But, if such a product exists, I could just clean out the crack again and nylon tape and this wonder elastic compound may do the trick.
Add another layer of 3/8" drywall to the entire ceiling, making sure no fasteners are directly below the truss joints, using mostly construction adhesives to allow some give.
Any suggestions or the name of an elastic joint compound would be greatly appreciated.
Thanks.
