I am doing a fist time "do it yourself" damp roofing job and am very inexperienced!
I have purchased some Knauf Vapour Panel Square Edge plasterboard from Wickes.
The description of the product is "Vapourshield is laminated with a metallised polyester foil to create an effective vapour barrier."
I plan to "dot and dab" the Knauf Vapour Panel to a damp proof membrane.
I just wanted to check that the dot and dab method will work since this plasterboard is a bit more specialised than the normal stuff. e.g. can you still dot and dab to the metallised polyester foil backing?
