Green Glue - Any idea what it actually is?
I've been looking at how to sound-proof an exaiting stud partition without having to remove the existing plasterboard.
There appears to be a British Gypsum product called Soundbloc which is like plasterboard by more dense. Apparently it can be bonded to the existing
plasterboard with a product called Green Glue which both sticks it in place and also isolates the new board from the existing. (Seems like it forms
a pliable skin between the old and the new.
Appart from the cost og the Green Glue the other problem is that it's made in the US and comes in larger imperial tubes which are too large for
a conventional mastic gun. You can get imperial mastic guns but by the time youve bought this, three tubes of the Green Glue and a single 8 x 4
sheet of Soundbloc the overall cost comes to around £100 which is a lot for a 4 ft long wall.
Does anyone know what this Gren Glue actually is and if there is a UK (or European) equivalent so I can at leat use my existing mastic gun.
Any other advice would be appreciated but I can't really take off the existing plasterboard and there's very little room to build much in
front of the existing. Just wondered about foaming between the existing platerboard skins.
John.

you say its a stud so just overboard it using longer drywall screws.
the sound board is quite a bit heavier than standard so you will want 2 people unless your not putting up full boards.
never heard of the green glue before.
not sure how effective just adding a layer of sound board will be though. if you did remove the old plasterboard you could fill the stud with rockwool
flexi or similar sound deadening insulation.

Material datasheet have to be supplied so you can see what it is here:

Basically a latex adhesive (note the MSDS is accidentally not available on the green glue site, bit naughty)
