Simple way to trace a profile of Cornice

Helping you

To help match your Cornice up which if its an older property, it may well have been Ran in-situ this is normally when the property was first built, but we can help you get a template made so it can be matched, we help regardless of you using us, we have done this now for many years.

First, some background to help you understand why you cannot find a match for the Cornice anywhere online

To check if it has been ran in situ! there are tell-tale signs to show show originally Ran in-situ, the main ones are the plaster Cove feels solid if you knock or tap it, the backing of it is enlaced with different core base material, normally locally found, also you normally find the main Ceiling is constructed using wooden laths, Then the Craftsman were able to create the pattern of the Cornice to run past into the Ceiling line easy, sometimes the wall too, *Modern Materials like Plasterboard doesn’t allow this the same* they Ran the Cornice first by placing wooden battens or guides prior to Plastering the main wall of the Room, some had a favourite shape or would be in-keeping with the period time or some even used a stylesbook as reference, they cut the shape in tin, fastened to a wooden right angled brace “Horse” then forced a bulk plaster into it running in situ serval coats until smooth top coat, each corner was made up by hand ans still is if we Run, using a Joint rule (which is same a a saw blade without the teeth) so they just picked a shape based on what was popular for that time period, after work was finished maybe doing a batch of homes, they just disposed of the tooling (Running Horse).

Now, How to reproduce that profile for the new matching Cornice, lets do it with Pictures

This is what we use Below

  1. We just need to cut into not through the Cornice, we use a Multi tool as above, you can use a Saw, grinder etc (but that’s Dusty) or sometimes just a utility knife.


2. You need to Pencil a simple side profile line onto paper following all the contours of the Cornice (example shows below) but keep the paper sitting on the ceiling and the wall too, this is all you need, if you supply this; it can cut out the need of using a Specialist company being called out at this stage, as distance can be a factor and this can be posted!

So to recap: Choose the area in the room where to cut through your Cove, cut a vertical line with your preferred tool about 3/4″ deep (no need to cut too DEEP all the way through the Cornice) you can trim the paper until it fits in the corner, the paper needs to be touching the wall and ceiling lines as above photo shows, so chop away cut it until the paper fits, the corner part beyond cove is not needed at all

Carefully trace the Cornice, after you have done that. You will end up with something like this in the Photo below.

You will be left with a tracing which also has 2 flat areas representing both the ceiling and wall

So because you didn’t cut a deep a groove in your Cornice, its easily to repair using fillers, sand or rub down using water and 120s or 180s Wet/Dry paper and sponge off.

Finally got there, dont forget the paper needs to be touching the 2 edges on the wall and ceiling like the ARROWS in above photo, so you are left with a pencil line drawing of a shape, you now have your template, job done

If we are making the Cornice for you, put your contact details on that same paper with amount needed and send it to: UKPlaster Vulcan Works, Dixon Street, Horwich. BL6 7PH Here is our Tel Number: 01204 693 900

  1. On receiving your drawing of the Profile, we confirm price, then Cut the shape from Tin you have supplied and fasten it to a wooden brace: Running Horse If only a small amount of Cornice is needed, let’s say 2m or less, we Run this direct on our bench.

2. If a larger amount is required, we do a similar procedure: only we cut the reverse pattern of the shape and run a length of that, which gives us a reverse of yours in plaster, only this time we cast lengths of this to form a Cornice from that reverse mould, make the amounts needed. 

3. The only other decision is: will you fit it or a fitter 

We do this mostly for Insurance Companies due to costs in labour which sometimes cannot be realised by an individuals and direct paying customers.


The use of an Oscillator to cut through the Plaster is a good choice, however a hand saw or angle grinder is equally effective (PPE) Personal Safety Equipment should be used.
