Been lurking on here quite a while and have found most of my answers.
However I have some confusion about overboarding a lath ceiling.
I run the boards at 90 deg to the joists -Yes?
But there are no noggins between the joists, just joists with the laths then plaster, so what supports thoses edges between the joists where you would normally put a noggin if you were building a stud wall?
Should I use some board adhesive to glue it to the ceiling?
Or will it support itself over the distance - 16".
Tape the seams?
Also 9mm or 12mm? I was all set to get 9m as I understood it'd be easier to handle and not sag so much. Then I go on the project page and it says to use 12mm on ceilings as it wont sag so much??
Thanks for reading this and helping out if you can.
Ok, so another question as I've had a good look and can't find any reference to it on here so far...
The room I'm overboarding is 3.5m x 3.5m.
I have the taper edge boards.
When doing the ceiling I'll need to join 2 boards end to end, i.e. no taper between them as the taper is only along the edges.
What should I do about this join?
Thanks very much for any help you might be able to offer!
A couple of things to do, if your joint taping boards to fill out rather than plaster. On your square edge you can fill out a broader area so the edge is not as noticable or you can shave the edge of board down, to put a taper edge on it.
The later is a bit more hassle. I find filling out square edges much easier and does the trick. Remember that you need to apply and sand down jointing compond at least three times to have desired effect.
