Levelling a ceiling

Recommended Posts

The job I have been putting off! Dropped all the old lath ceilings in our house reno last year. Nows the time to think about putting them back up. Problem is the floor and ceiling joists are all over the place.

 

A builder recomended battening the ceiling perpendicular to the joists and packing them out to get them level but I am not sure what size of batten to use and if rough sawn would be acceptable. Would be looking at 12.5mm plasterboard at a minimum. 
 

Any advice much appreciated.

I used 2”x1” tile battens perpendicular to the joists to overboard old  Artex ceilings then the 12.5mm plasterboard.

Rough sawn is fine. I assume your joists are 400mm centres? Ceiling battens perpendicular to ceiling joists.

The centres aren't even. The house is ex-council built in the 50s so the standard isnt great. What size would you recommend?

Ok great thank you. I am sure the builder said to use 4x1 which just seams overkill to me but wanted to make sure.

I would add a binder and some hangers , generally old ceilings sag as joists were undersized and without intermediate structure

Under-batten with packing where needed to level the underside or side batten with 3x1 or even 3x2 (makes hitting them with fixings easier) along the joist length. Only needs to be one side of the joist.
