6 mm plasterboards glued with Gyproc G66 - degree of contact with the substrate

[Pontstone]

Hello everyone,

I have people here gluing up 6 mm plasterboards with Gyproc G66 adhesive. The substrate is plastered walls that are a bit uneven. When I knock on the glued boards, I notice that in some places it sounds like knocking on stone, and in other places, it sounds hollow.

Is this normal? I assume that where it sounds hollow the board isn't adhered to the substrate.

Should I calm down, or should I get on them and have them redo the job?

Thanks for the answers!

You usually apply this glue in strings. That's why it sounds different.

You can be at ease as long as the booms are less than the manufacturer's specified maximum cc dimensions.
