Crown Molding For Cosmetic Truss Uplift Fix
I've read (I think) as many posts as I could search here re truss uplift. It's not the definition that confuses me. I've been well acquainted w/it for the 20+ years I've lived in this house. :( I know the only proper way to "fix" it is to do the recommended work from the attic down. i.e. use the proper clips; 'detach' the nailed drywall from the truss, etc. We're both a bit compromised healthwise, so that kind of job is not an option. We could hire someone, but a 'fix' like that is quite expensive. Not to mention finding building contractors who are familiar w/the problem and familiar w/fixing it. (We had a leak in our bathroom ceiling a few years back and had to have it completely ripped out and re-sheetrocked. Figured w/the guts exposed, we might as well get that section of the usually 'uplifted' ceiling fixed. The contractor never heard of truss uplift! WE had to walk him and his guy through it! It came out okay in the end, but wasn't cheap by any means.)
So w/that route out, my only other alternative is cosmetic coverup w/crown molding. Which I'm fine with. I happen to like the addition of the crown. Problem is - despite all the recommendations on the web to do this, no one says exactly HOW you're supposed to just nail the crown to the ceiling. It's not like I can depend on hitting a stud like I would if I were nailing it to the wall. Plus the thought of a nail every three or four feet - or however long the distance between nails would be - sounds rather precarious to me.
We've been toying w/the idea of using one of those polystyrene formed moldings. There's one that sticks on w/a glue and another that's peel-n-stick. Admittedly, it would be a little less daunting to hold up an 6 or 8' section of poly than wood or wood composite. But I'd like to consider all the options for materials just the same.
So, does anyone - anyone - have any experience or knowledge of how to nail a crown to just the ceiling (if we have to go the wood route) and not have an 6 or 8' section come crashing down on my MIL's head next Christmas? And has anyone had experience with or knowledge of the poly moldings - either glue on or stick on?
Thank you for any help you can offer. Sorry for the long post. I figured the more info I supplied the more it might help . My kitchen remodel is hung up till we can square away this molding business. :(
