I need to replace a damaged section of plasterboard on a stud wall and am hoping to cause minimum damage.

What's the easiest way to cut a rectangular section of plasterboard out? I want the cuts to centre on the studs so a saw wouldn't do in this case. I guess a Stanley knife with a good blade might be enough, but would this be rather hard work?

Suggestions welcome

Mutli tool about £40 at the cheaper end.

Is the plasterboard skimmed?

Plasterboard cuts easily with a Stanley type knife. It may be easier to
first cut down close to the the edge of the stud, remove the board to
that point and then make a second cut in the middle of the stud.

The alternative if you don't need to go back to the stud is to cut out
the damaged section and glue/screw some (scrap)plaster board or wood
batten behind the existing sound board give something for the patch to
be screwed into.

Picture at https://photos.google.com/photo/AF1Q...GEByKcodtAdy28.

The stud wall is partly behind the old airing cupboard which has been removed when changing to a combi boiler. The plasterboard has been skimmed from the 'good' section to overlap the stud but the 'bad' part was behind a false wall (now removed) and wasn't skimmed. It had pipework going through it in various places (which has now all been removed), and is in generally poor condition, which is why I hope to replace the complete section.

The section below the picture also has several pipe holes in it and needs replacing too.

Quickest and easiest is an angle grinder with a 1mm steel cutting wheel.
These will cut anything.

You'd do a job like that with the doors open?
Anyway it didn't happen for me. It didn't make tiny particulates. It
mostly fell on the floor.

A Stanley is what the pros use. You just need to nick the paper along
one side, then it will snap where it is weakened by the nick.

It works as easily as that for un-fixed plasterboard. It will be a bit
more difficult once the board is nailed/screwed into place, you might
have to score all the way through the board.

Multi-tool would be my choice, you could do it with a stanley.

In order of preference: Stanley knife, oscillating saw, floorboard handsaw.

It can be done with a saw! However the easiest way is with a multi tool
cutter.

I find it easier with a 3inch circular saw set to the correct depth and
using a carbide tipped 1mm thick blade.

Any handheld circular will do it, but you don't really want to hit a screw/nail with one, and the OP is cutting over the uprights.

I used a Dremel with a diamond blade!

Angle grinder like i said

Bill

In the end it turned out to be quite straightforward using a Stanley knife. Many thanks for all the suggestions.

I see what you mean about cutting to the centre of the stud, to give a
fixing for the new board. Yes, you could cut with a Stanley knife. Not
really hard work.

I would begin by taking out the old PB up to the edge of the studs
first, using a hacksaw blade in a Stanley knife type handle (not a
frame). That just leaves a strip of PB attached to the stud. At least
then you get a better idea of exactly where to cut with the knife, and
can probably easily see/feel best way to remove the strip.
