Calling all DIY experts out there.. I have a slight dilema and here it is..
I have to replace my Celing due to it sagging i don't know if 1) Rip the old one down or 2) put the new plasterboard over the old..
I have tried to locate the joists through the old plasterboards just in case i chose to do the 2nd option but im just making hole everywhere as i know they SHOULD be space about 40 cm apart but that is not the case on some of em :evil: [b]what is the best way to locate these joists??[/b]
also I have noticed that there is thin wooden slats running the opposite way to the joists all along the celing I have not found any noggins yet so im don't know how im going to screw the plasterboard down the side of the board [b]would it be ok not to screw the boards between joist or do they have to be screwed??[/b]
Any help on this would be Appreciated :D
