Green Glue is ineffective so far on existing wall - further solution?

[ryanpatrick76]

I have an existing party wall in my new duplex condo. The noise is airborne and impact. I installed 5/8" sheetrock and greenglue to my side of the wall. It has been up well over a week and the noise has not changed at all. It is just as loud as it was before.

What are my options?

Thanks!

On the Greenglue Company website, it says that it may take up to 30 days for GG to chemically 'set' and become fully effective. 

If you added 5/8" drywall, then the noise is certainly not 'as loud as before'.  You're judging subjectively, and your ears/mind can trick you.  Get yourself an inexpensive sound level meter and you can accurately test the results.
