Removing Door and Plasterboarding

[leedsit]

Hi,

I have a door in my living room that I want to remove. When building the new partition wall for this, do I need to seat the new plasterboard in the space level with the current existing wall plasterboard, or sink very fractionally for the plastering? I have this thought that If I seat it level, when plastered there will be a slight bump?

Hope that makes sense.

yup sink it, iirc, 2 coats of multi-finish (which is what you'd be doing or having done in the uk) come out at about 6mm. (generally 3-4mm for the 1st coat and 2-3mm for the 2nd).

Is the door in a block work wall or timber stud wall?

Thanks for the replies, The door im going to remove is in a Timber stud wall.

If you keep it flush you can have the whole wall skimmed over for neatness, i would be inclined to cut back the existing plasterboard enough so that you can screw the two mating bits of plaster board (old and new) to the same stud as where two studs are nailed or screwed together with a seperate plasterboard on each, when the studs expand and contract hairline (or bigger) cracks can appear.

thanks all and especially 1john, exactly the kind of advice i was after.

What I would recommend also; different scenario with a block wall though which is why I asked.

multi finish is a 2-3 mil skim in total " ie" after both coats applied

My local authority clearly stated that there should be 3.2mm of skim over boards, although I have never seen anyone measure lol

really? i thought you guys put that stuff on much thicker. what are the 6mm beads for then? bonding + multi?

They are a hangover from the days when board finish could be put on heavier, when it had more body - as you say a coat of bonding was needed.

Look on the bag, BG say 2mm of finish!

That's an eighth in old money - rounded up to mm.

Done by another numpty who does not understand real life - why do they just not just say 3mm?

Or why not ring up BG and ask instead of using an old spec for reference?

i wish i could get it here

In Fairness, your boardwork has to be good for 2 mm - but in the real world, a heavier first coat just means you need to leave ti a bit longer to pick up before you flatten and lay down with your second

I forgot to say, in the days' of the old 5-6mm spec for board finish, it was a case of coating over jute scrim everywhere instead of the fibatape of today
