Hello

A local club is looking for fix up their acoustics. It is a live performance venue and the place is way too acoustically lively, much of it due to all the open ripped steel decking from the exposed ceiling. I can't even walk in the place if there is more than 10 people in the building talking due to the annoying acoustics.

I saw a spray on coating at a trade show in the USA years ago that was perfect for this purpose. It was not Cellulose, but like a porous plastic-like material. I remember all the specs were impressive, and it could go on fairly thick if required. I can't remember the brand of type of material, and Google is not helping me find it again either. Anyone? Thanks. . .

Ok, maybe it was a cellulose based product. I kept googling and finally came up with K13, which seems to be the spray on coating I had seem sample of before.

This is another interesting product: http://www.acoustop.com/pdf/quash.pdf
I have some small samples at home, it appears to have interesting properties. It should make great improvements to the acoustics when installed on large vertical surfaces such as concrete block or drywall.

Any comments?
