It is not a bad idea. It is done with special acoustic glue - it is very gooey and doesn't dry hard like most glues. Good damping. They suggestion you apply it in a random pattern and not stripes or dabs to avoid creating sharp resonances.

I don't know if you can get it where you are, but perhaps once you see it you can find something similar or at least read the instructions to get some tips... And, BTW, they still want some screws for mechanical strength and to satisfy the building codes.
