I've read many coments suggesting that you can't dot and dab with foil
backed pb. However, my plasterer is here this week and says you can
and did so while here just fine stating that the adhesive will stick
to pretty much anything.
So is this right or wrong?
I tried it once out of curiosity - I would guarantee that once the adhesive
has gone off, the only thing stopping the board falling away from the wall
would be the tape/scrim and the skirting. Drywall adhesive IS sticky but
will NOT adhere to foil backed plasterboard for any length of time once dry.
You can call British Gypsum technical helpline on 08705 456123 and the
knowlegable staff there will give you a definitive answer.
What are the benefits of foil backed plasterboard? I assume some
insulation benefit? What is the u value of PB with and without foil? Can
it also be used as a vapour barrier or are the joints a problem? Also
how much more expensive is it?
....so many questions...so few answers :-)
Just to update for the records.....
Do not ever, ever let your plasterer dot and dab foil backed boards. I
just pulled them off and they came it extremely easily, the foil
surface doesn't have a single bit of adhesive left on it.
My plasterer had over 25 years experience as well. Just goes to
