The Butt Joint:- Used to join 2 pieces of skirting baord along its length
Although this method is the easiest and quickest way to join 2 lenghts of skirting board together it will
probably remain highly visible after decoating and will also be prone to cracking
The Headed Mitre Joint:- Used to join 2 pieces of skirting baord along its length
when you need to join lengths of skirting board together to make it longer the best and neatest way is to
use the Headed Mitre Joint. This method has several advantages over the easier Butt joint method.
This joint will be easier to sand down and blend in, than a Butt Joint and the joint line will be far less visible
after decorating, if the joint is cut correctly.
The internal Mitre Joint:- Used to join 2 pieces of skirting baord at an internal corner.
This method of joining internal corners is probably much quicker and easier than the correct
scribe joint. It is not normally recommended because there will be gaps in the joint if the walls
are not square to each other and the joint will crack and open up when the boards shrink or
expand with changes in room temperature and humidity.
Internal Scribed Joint: - Used to join skirting boards together at an internal corner.
Although this joint is trickier to cut than the internal mitre, this is the correct and best way
to join skirting boards at an internal corner. Only the one board needs to be scribed and it will be
okay to use on corners under 90°and if it is undercut it can be used in corners above 90°.
The external Mitre Joint:- Used to join 2 pieces of skirting baord at an external corner.
Probably the only way to join 2 skirting boards together at an external angle. Normally this joint
is cut at 45° each side to create a 90° corner but with care can be adjusted to suit joints above or
The Architrave Mitre: - Used to join together the legs and head of architrave door sets.
Unless you plan to fit Rosette Blocks this is the only way to join basic architrave legs and heads
