I have a sandwich of DW+GG on my basement HT ceiling. Only problem is that it is coupled (my ignorance ) .
Given that I can't take it down b/c
(a) my wife is very sensitive to dust, and would flip if I took down the ceiling causing tons of dust to go up to the now exposed 1st floor (exposed - other than the flooring)
(b) time/cost to take down the ceiling
(c) in addition, there's drywall compound spackle over the ENTIRE ceiling (again, my ignorance) and from what I've read this is dangerous to breath in , and takign down the ceiling may cause it to become airbourne.
That being the case (that the ceiling is coupled) - AND my only concern (other than safety) is keeping LFE from getting up to the joists, and then through the house.
My Q is - how many layers of 5/8" DW and how many GG applications would give the same LFE containment as I would have gotten had I done it "the right way" and decoupled the wall to start + DW/GG. i.e. how may layers would I need to keep the LFE contained in the HT?
btw - I'm sure you already know this, but I've got to say that Ted White is by far the biggest help and a Genuine help and not just out to make a sale. I've called him multiple times, practically begging him to buy more stuff from him - and he keeps on giving me other alternatives via standard materials. Through his help, I've shored up the rest of my mistakes, and now (I hope) remain with only the problem of the ceiling. I feel guilty calling him again (plus interested in consensus) so I'm posting the Q here, but Ted: thanks so much, I'm very grateful.
