Q How to cut plaster coving?
We get lots of questions about how to cut the perfect internal and external corner of your plaster coving. Before we go through this, the first thing to remember is that even the professionals use filler – and lots of it – so set your expectations correctly before you do this. The cut is going to be as smooth as possible, but you are always going to have to make good any plaster coving or plaster cornice joint by standing on a ladder with little bits of filler in your hands and moulding the shape correctly.
Firstly, you are going to need a good deep mitre for your saw. You should be able to get this from any local DIY superstore. You will also need some large nails for guidance, a sharp fine tooth saw, some sandpaper, some fine filling and you are also going to need lots of patience. Without every one of these ingredients you are going to make a dogs dinner of your plaster coving.
Choose whether you are doing an internal or external mitre – even the experts get this wrong – hold up your coving where it is going to be and double check whether the angle is is acute on the ceiling or obtuse. Mark the coving on the corner of the wall and then position it in the mitre. Nail the mitre to a surface (not the dining table) and use nails to keep the plaster coving steady.
When cutting, plaster coving offers very little resistance to a sharp fine toothed saw. Our hand made plaster coving contains traditional strengthening fibres which will offer a little bit of resistance – but you should allow the weight of the saw and the action to do the cutting. If you push on the saw to speeden up your cut, you will probably only succeed in creating a jagged cut.
