Finishing plasterboard joints around existing wall/ceiling

[Markmitch]

Hello,

I wonder if anyone can help me...

I plan on separating a large bedroom by building a partition wall to create a smaller bedroom and separate home office. I plan on building this from timber and plasterboard. To keep costs down I plan on painting the plasterboard after it has been finished rather than having the whole thing plastered. I am fairly confident about building the actual wall and installing the plasterboard however I am a bit unsure what to do with the joints where the new wall will meet the old wall (left and right) and also the ceiling. In understand I need to use tape to reinforce the joints and I was planning on using easi-fill however will this not leave a slightly noticeable ‘raised’ area around the partition wall – even after sanding? Has anyone got any tips?

I was also planning on using tapered edge plasterboard. However after planning the whole thing I am only going to have 1 full tapered edge join – basically because of the size and also where I plan on installing the door. The other joints will be standard butt joints. Is it really worth using tapered edge board for the benefit of 1 joint – different if it was a full sized wall or ceiling I was doing?

Any help would be much appreciated!

if you use tapered boards these are then taped and jointed to create a smoothe finish,idea is to build a wall using the tappered boards to keep it level.
if you end up with butt joints then to blend these you need to cover a bigger area for feathering.
to finish against walls just use decorators chaulk.

Many thanks for taking the time to reply.

Is decorator’s chaulk okay for around the corners? I will be buying a bag of easi-fill anyway. I don’t mind taping the internal angle joints as well if this is the best way forward. I was just concerned there would be a noticeable build up of filler around the new wall where it meets the ceiling and existing walls. Long as it will look pretty decent I don’t mind. I know the only way to get perfection is having it plastered but I really don’t want to go down that route for a stud wall which hardly anyone will see.

Thanks again

Sorry meant to add this to my previous post.

If I go ahead with using tapered edge plasterboard is it ok to start in a corner (where the old wall meets the new stud wall - 90o angle) with the tapered edge or is it advisable to trim this of in this situation.

Thanks again.
