I still think the stuffs a gimmick.
Surely if your still having to glue certain areas because they’re high suction then maybe that suction needs to be controlled with PVA ! it’s not like it takes ages to do.. It’s like BG are trying to solve a problem that isn’t even there.
On your video surely having to get the top half of the wall to near finish then 3 coat the bottom because the suction is to great, can’t be less hassle than gluing it up first thing whilst having a brew then two coating with multi or board.
Not slating any of your work mate, just can’t see this being the future.
