		In some situations, such as when fitting coving around chimney breasts you may have a very small section of wall. On these walls it is better to fit one piece of coving with mitres cut at each end rather than using two pieces butted together.

		This will create a neater look with fewer joints to sand over once the coving has been fitted. However, this does require paying more attention and care to the measuring and cutting of the coving.

		When taking measurements for a section of coving with mitres cut at each end, all measurements are taken along the wall (not ceiling) and are marked on the wall edge of the coving.

		The following guide is given for the coving fitted to the short side sections of a chimney, that require an internal mitre cut at one end and an external mitre at the other.

		For the longer face of the chimney you will require a right-hand external mitre at the one end of the coving and a left-hand external mitre at the other.

		For the wall sections either side of the chimney you will require right-hand internal mitre cutting on one end of the coving and a left-hand internal mitre on the other end.

		Step 1 – Cut first mitre If you are cutting the coving for the right side of the chimney (from the chimney’s point of view, looking out into the room), begin by first cutting a left-hand internal mitre at the far left side of your coving. For the coving fitted to the left side of the chimney, begin by cutting a right-hand internal mitre at the far right side of your coving.

		Step 2 – Measure wall Then measure the length of the wall. Mark this length from the cut mitre, along the coving’s wall edge.

		Step 3 – Position cove mitre If the first mitre you cut was a left-hand internal mitre then place the right-hand face of the cove mitre up against the mark you have placed on the coving’s wall edge. If the first cut was a right-hand internal mitre then place the left-hand face of the cove mitre up against the mark you placed on the coving’s wall edge.

		Step 4 – Cut second mitre With the cove mitre held in this position, cut the second mitre to achieve the length of coving you require.



		Once you have cut the coving with the required mitres at each end, fix it to the wall following the same procedure as described on the How to fix coving in place section of How to cut internal mitres using a cove mitre.
