Installing door trim simply and effectively

Installing door trim is a DIY project that is easy enough to complete. With the right high-strength adhesive, the job becomes even easier!

How to install door trim: What is door trim?

Door trim has been a staple of interior design for several centuries now. It was originally used to cover the gap between the aperture in a wall for a door or window and then, inevitably, became a more decorative feature.

When choosing your door trim, try to find some that compliments and works well with any coving, skirting and dado railing that the room contains. Once installed, you can be as creative as you like with colour – white is standard, even with walls or wallpaper of a different colour, but painting trim the same colour as the room instills a pleasingly unified aesthetic.

How to install trim

With a few simple measurements, a mitre saw and a high-strength adhesive, installing interior door trim is a simple job.

  1. Reveal. Place a set square set at 1/8 inch against the door jamb, hold a pencil against the end of the set square’s ruler and run it along the length of the jamb to draw a line for the reveal. Do this on all three sides of the jamb.
  2. Head. Measure the length between the two pencil-drawn vertical lines to calculate the length of the bottom side of the head moulding piece of trim.
  3. Cut. Setting a mitre saw to a 45-degree angle, cut head moulding piece first, using the measurement from step two.
  4. Glue. Glue the head moulding piece in place by applying a saw waved-shaped bead of your adhesive to the rear side, then use the vertical reveal lines and a spirit level when positioning.
  5. Sides. To calculate the length of the side moulding pieces of trim, measure from the corner of the head moulding piece to the floor. Cut the pieces at 45-degrees with the mitre saw and glue in place, aligning them with the head moulding piece and the vertical reveal lines.
