Coving Joints and How To Do Them Without Tears

Stuart · 2006-08-24T21:38:02+00:00

I am putting 100mm plaster coving around my bathroom ceiling .I have just doneone seperate section that consisted of 3 straight short lengths with twostraight ends and two internal corners and that was bad enough .The main sectionstill to be done is about 8 Metres with 7 internal corners and 3 external .I am looking for tips as to how to do this with the minimum of trouble .I wasusing a small plastic device called a Wonder Mitre .I got it years ago but I seeAxminster have it here one I have is plastic and tends to spread when you put any pressure on itand if you don't it slips off position . Looking at the Axminster one it lookslike it might be metal so it could be more practical ..I'd prefer to make a halfdecent job so minimisiing the use of filler although I may be optimistic insaying that .Any advice will be appreciated .thxStuart

The message from "shaun" contains these words:

Make it so the cove sits upright. Not hard to do, just make the gap between the sides of the box the same as one face of the cove not its diagonal length. Once it's made, drop it into whatever mitring system you already have and cut a slot for the blade. Or just mark it with a protractor and saw carefully down.

I helped Dad make on in the late 60s and we did the whole house with it using Gyproc.

'Sloping joints' are more usually referred to as 'Scarf' joints .

The scarf joint is not preferred when strength is required, so it is most often used in decorative situations, such as the application of trim or moulding. The scarf joint is commonly used in construction fit out tasks, including fitting of skirting, picture rails, dado rails or chair rails, handrails etc..

BTW: for coving, dado, chair rail skirting board etc ... buy a 'Magic Mitre' (QVC). It'll solve all your problems including the scarf joint.

Indeed, I use a plastic mitre box - as did my plasterer who did some of my coving as well. the coving is a bit smaller than the width of the box, but that is easily solved by fitting piece of batten etc. in of just the right width to hold it in square.
