Plaster Coving Installation - How to cut an internal mitre on plaster coving without using a mitre box.
This is the second video in a series of Quick Coving Tips that explain plaster coving and plaster cornice installation.
Step 1:
A professional plaster coving installer describes in detail how to cut an internal mitre, which is for a corner that goes into a wall.
Step 2:
Typically a mitre box is used for this, but in this demonstration, the installer shows that simply by measuring and allowing for the depth and projection of the coving a perfect internal mitre can be cut.
Step 3:
The plaster cornice is laid on a bench with the ceiling edge against the installer and the wall edge away from him. With an internal mitre, it is important to remember that the projection measurement of the cornice is always subtracted from the top edge of the coving and the wall edge is held at the correct depth on the bench before cutting commences.
Step 4:
Following the simple tuition guidelines, explained by the installer on two separate pieces of coving, will create a perfect 45 degree internal mitre. Perfect does not mean without some chips or flaking caused by sawing, these disappear during the filling phase.

Please what is the Projection. Is it the size of the piece that projects from the ceiling outwards.

Hi John. In the perfect world that would be the way to cut the mitres but I find most bays are not that precise. The best way is to mark the projection of the cornice on the ceiling all the way around the bay. This will give you the intersections of the top of the mitres. Then working from left to right offer the first piece up and mark the intersection on the cornice. For example if you are going from an external mitre to an obtuse internal mitre cut your external, add the measure of the wall to the bottom edge and do a straight cut. You can then offer it in place and Mark the obtuse internal intersection. This can then be cut. Before you fix this in place cut the next piece with two straight cuts and Mark the intersections. Working this way means you always need to Mark the next piece before fixing the current one in place but it will give you the perfect mitre. Hope that makes sense
