INSTALLING DOOR TRIM and fitting architrave for door frames

Installing door trim and fitting architrave for door frames are DIY projects that are easy enough to complete. With the correct high-strength adhesive, these jobs become 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 fit door architrave: What is architrave?

A door architrave is the line of internal moulding fitted around your doors and windows. It is the strip of material that rounds off the wall and door. Internal door architrave is mostly decorative but installing door architrave can hide any gaps or defects in the joins between your door frames and walls and shield your door frames from any bumps or knocks. 

Just like with door trim, it’s important to choose architrave pieces that work with your skirting boards and design style. 

The best adhesive for installing trim around doors and installing door architraves

With the correct high-strength adhesive, you can eliminate the need for a hammer and nails or nail gun when installing trim around doors (likewise when installing window trim) and fitting architrave for door frames. UniBond No More Nails Original is perfect for heavy-duty adhesion when bonding and mounting. 

Specially designed for interior use, it is ideal for installing door trim, installing door architraves, coving, skirting board and many other internal bonding applications. This multi-functional grab adhesive is suitable for most common building materials such as wood, ceramic, metal, concrete, brick, stone, plaster and most plastics. Ensure that at least one surface is absorbent, and in case of painted walls, the paint must be well bonded to the walls. Additionally, bond only on clean, dry surfaces free from loose material, dust, oil, grease, and polish.

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.
