I would think that the T & G floor above is tying those planks together really tightly as it is...

Yes, you caught me. I did fill the gaps in one application,knightfly wrote: If everything you've tried cracks, it's probably because
you filled the entire crack in one application; a lot of
materials warn against filling deep cracks with a
single application.
Although I haven't tried the actual gaps, I set up the testsknightfly wrote: I'm also wondering if you've actually tested the REAL deal,
or just the mock-up you mentioned? Specifically, are the
cracks between your T&G flooring as deep as the ones in
your test?
I think I can understand that (that's the same issue weknightfly wrote: Also, even a cracked fill is better than an UN-filled crack
(damn porn spam; now it's got ME doing it too)
because the smaller the crack/shallower the air gap,
the higher frequency it's tuned to and the easier it will
be compensated for by your beef-up.
Acoustic caulk would be expensive, but I supposeknightfly wrote: If all else fails, I'd fill those cracks with acoustic caulk
just before putting up your first layer - I'd make sure
you don't fill too MUCH though; you want that first layer
up tight against the floor. A slight under-fill would be
better than too much. Any decrease in the depth of the
cracks will be better than none.
That's somewhat of a worry of mine.... would hateknightfly wrote: Another reason for using acoustic caulk - even if it

be the case with something that hardens... Steve
knightfly wrote:Now I'm getting confused; is this subfloor actually T&G, or is it just straight boards with cracks that go all the way to your finish flooring? (If it's T&G, you shouldn't be able to see your finish floor from below)
Either way, the more I think about it the more I'd stay away from any RIGID filler; wood expands and contracts with moisture content, etc, and that's the reason for NOT putting the subfloor in without spacing between boards. The only reason this isn't done for finish floor, is that it looks like crap and the finish floor will usually be in a more stable temperature/humidity, so wouldn't tend to be damaged by not leaving gaps for expansion...
