Fill up gap between door frame and surface of plasterboard

bleicker · Post by **bleicker** » Sat Aug 13, 2022 10:00 am

One of the sides of my wall is around 10mm off level to my door frame as I built up 3 layers of plasterboard with tecsound in between to lower the noise transfer, as this is a home office. I was thinking about how to fill this gap with a strip of wood, but I need to plain it at an angle and I've no idea how I can best achieve this. maybe there is a DYI friendly tool to assist with that? I was thinking even about using a wood filler, but I guess it would be too much at the top where the difference is 10mm, but maybe at the bottom where there is little difference it would work? I hope the pictures help getting a better idea? Thanks!

The easiest way is to glue on some quadrant bead which can either be wood or plastic. You will ned to cut neat mitres at the top of the frame. All you really are doing is neating it up so the eye is not drawn to the exposed plasterboard edge.

My idea was to fill that gap so I can cover it with architrave, what you propose is to not use architrave and use the beads to just match the plasterboard as it is?

Or as alternatives.
Plant a thin strip onto the frame and fix the architrave to that then use filler in any gap between the architrave and the wall.
Or better but requires a little more work and tools is to rebate out the back of the architrave. It's literally a case of cutting the archs holding in place and running a pencil down the side where it meets the plasterboard. Plane it out to that line to form a tapered rebate , obviously not touching the edge that sits on the frame.
Edit to say that you'll need either a hand rebate plane ( easy for me to say as I carry one as standard) or a power planer as these allow rebates to be cut.

Ah, a power planner, mark the wooden strip against the plaster so I know how much I need to take off. excellent idea!

Sorry I did not read your question properly. I would fit the uncut wood trim all around the frame. I would then run a router with a guide bearing to level it off with the wall, you will get most of it done as the router base will stop you from passing through to the end which means you will have a small section to do by hand planing.

I great, I have a routing tool, I'll try to use in this way then :)

This video will give you a better idea, in your case the bearing follows the wall. It will be best to use a small router as the base is smaller and it will leave less to hand finish which could be done with a chisel https://www.youtube.com/watch?v=FPUyE8XaEQM
