Intrim’s Top Tips for Joining Skirting Boards

Depending on where you require the join, will depend on the type of application for joining you use. See our quick tips for joining skirting boards in different areas of the wall.

STRAIGHT WALL JOIN

If you are joining skirting boards along the length of a straight wall, e.g. where you require to install more than one length of skirting along the overall length of the wall, you will need to join using a splice or scarf joint.

A splice joint is made up of a 45 degree cut through the thickness of the skirting board, on the end of each skirting board where they meet. There is a 45 degree cut to the front face of the first skirting board to be installed and a 45 degree cut to the rear face of the second piece of skirting board, so it covers the splice cut of the first piece of skirting board when it is installed.

This splice joint is recommended to fall on the centreline of the vertical framing stud (timber or metal) position, that is behind and supports the wall lining board (normally plasterboard). This will help support the skirting splice joint, particularly if it is a high skirting board.

Apply PVA wood glue to the join and nail through the splice joint into the stud to minimise any cracking to the joint, caused by future expansion and contraction within the building structure.

INTERNAL CORNER JOIN

To ensure you achieve the best look and a tight joint with no unsightly gaps, you need to scribe the skirting board at the internal corners instead of mitering it. In simple terms, this means fitting one board flush to the corner then cutting the other along the detailed profile of the skirting so it fits perfectly up against the first piece, like a 3D jigsaw puzzle piece.

EXTERNAL CORNER JOIN

To create a join on an external corner like pictured below, the process is relatively simple using a 45 degree mitre joint (assuming the wall is a true 90 degree corner).

If the opposite end of your external join is an internal mitred joint, we recommend you cut and fit that end first, and make sure you have at least 50mm overhang over the external corner.

Once you put your skirting in place, use a pencil to mark the back of the skirting where the corner of the wall is.

Set your mitre saw to 45 degrees (or adjust if the angle is not a true 90 degrees) and cut to create the mitre. This is best achieved by placing the skirting onto the saw bed face down so you can see the pencil line, check you’re square and cut, keeping the saw blade to the ‘waste side’ and leaving the pencil line in.

Repeat the process with the other skirting and trim off any excess until you get a tight fit where the mitres meet and you get a close fit to the wall.

Nail the lengths of skirting at the studs, apply a little PVA wood glue to the mitre join then cross nail to secure. We recommend drilling pilot holes on the mitre and close to the join to avoid splitting the timber.
