Hi
My rooms have been boarded with 2 layers of 12mm. When joining new plasterboard to this do i need to apply tape to each layer seperately or is tape needed only on the top most layer.
The facing surface will eventually be half tiled and i dont know if need to allow for movement between the two layers of plasterboard.
Thanks for any advice
