Ceiling is 35 degrees with 150mm beams at 1100mm centres. I want to fix ceiling battens (finger jointed 75x 40mm) under the beams and 10mm gib . What spacing should I fix the battens at? any advice much appreciated.
Of course you are going to run the gib at right angles to the battens yes?

cove adhesive 90 is better than 45 for back-blocking, gives you more time. Yes for a central screw, with 2 blobs glue each side on the batten; If you use Ultraline I think you can space the battens to more than 400mm, check the Gib site-guide online.

You don't need to back block edge joints, just normal tape and stopping, and you shouldn't have any end joints if you get the correct length sheets.

you do have to back-block edges of Gib above a certain number of sheets.

May I ask why you are using only 10mm gib with battens at 400mm cts? Its cheaper and a better job to use 13mm gib and battens at 600mm cts. Back block using cove adhesive. Blob of glue at 300 and 900mm and a screw at 600mm.

go for 13mm,you only do it once so don't skimp on the cost. 13mm being thicker dosn't follow every bump and hollow of the battens.

Why do so many people ask questions on here about gib? They have so much literature about there product available from all building merchants. Also I presume it would be on their web page.
