This short video offers a profile of an external trim, how they are designed and when is best to remove the protective film. With this video, you will be given a step-by-step guide on how to secure your trim.

What we mean by ‘external corners’

When it comes to cladding a room, there will be many different kinds of corners to contend with. Referring to corners as external and internal doesn’t apply to whether they are inside the house or not – in fact, it refers to where in the room they are.

If a corner is internal, this means it is the corner on the inside of a reading nook, for example – this corner is recessed. External corners are those on the outside of the nook.

Tools required

  • Trim
  • Tape measure
  • Tin snips or mitre saw
  • Drill
  • Screws

Step 1: Measure your trim

Using the tape measure, measure the length of the wall the external corner sits on. Keep a note of this measurement.

Step 2: Cut your trim

Mark the length of the external corner and, using tin snips or a mitre saw, cut the piece of trim to size.

Step 3: Install your trim

External trim should only be installed after coving, the internal trim, and the wall panel itself. Each of these items should be secured and in place, and the external trim should be added last, to finish the wall off. Use screws and a drill to fully attach the external corner trim to the wall.
