Plasterboard (overboard) ceilings

markwm

We're decorating a house that's been semi-modernised. All the ceilings are wallpapered with thick old wallpaper and it's !!!!! to get off.

As I understand the best option is to overboard rather than pull down the current plasterboard and then have a plasterer skim the new board.

I figured it might save money if I do this for all the rooms instead of the plasterer(Just the overboarding).

I have a couple queries...

1. Any tips on locating the position of the joists?
2. Do you need to pre-drill for all the screws? or will they go straight in?

Anything else I should be aware of?

1. Get one of these!

2. I usually drill a slightly-smaller pilot hole, but I'm pretty sure they should go straight in

You can find the joists by either a gismo sold by all the DIY stores or find the gap between the joists by going in the loft measuring the gap usually 16" (but can differ) or tap in a nail where you think the centre might be and do the same across the room does not take long, and go from there .

Just drive in the screws no need to predrill. To aid in putting up the board make a letter T from wood that will tightly fit between floor and ceiling, just kick it in place easier to screw the boards then than 2 guys holding it.

Ensure you stagger the joints like on this page- Plaster boarding a ceiling

Make sure you use the 12.5mm thick sheets as the thinner stuff is no good on ceilings.

Use plaster board screws to hold the sheets up and make usre you sink the head of the screws just below the surface of the sheet, but without tearing the paper. You will need longer screws than normal, perhaps 60-70mm

A good quality drill driver is best to screw the screws in tight and good fitting screwdriver bit.

And also get at least one of these, even if there are two of you doing the job:-

A big sheet of 12.5mm plasterboard held above your head is not light in anyones book.
