I'm going to show you how to install architraves.
The tools we require for the job is a nail gun, a mortar box, a saw for the mortar box,
hammer, square, PVA glue, tape measure, safety equipment, architraves, step ladder and spirit
level.
First thing we need to do is measure and cut the bottom architrave.
We've got to measure between the reveals and then we're going to add 5 millimeters.
Reason is we want the architrave to be on the outside of the reveal.
I'm going to measure now the inside of the reveal.
I'm now going to add 5 millimeters, transfer the measurement onto the architrave and cut
the architrave ends on 45 degrees.
The next step is to cut a 45-degree angle on the end of one board.
To do this I'll need a mortar box and a small hand saw.
The mortar box that you get will have a 45 groove already indented onto the mortar box.
You can use this to cut your 45 for one end.
Now I'm going to measure the architrave from the inside point, measured to an inside point
and cut on the 45 degree mortar.
Now I've measured the length of internal measurement and added on 5 mil.
It's now time to cut an opposite 45 degree angle on the other side of the architrave.
I've cut a small piece of timber and I'm going to use my teammate Bo and he's going to help
me align the bottom architrave by using the small piece of timber so he doesn't have to
carry a huge piece.
So now we're about to attach our bottom architrave.
What we're trying to do is keep that 2.5 mil step from the reveal down to the architrave
and try to maintain that through the rest of the architraves around the window.
Now we have fixed one end, it's time to fix the other end.
Go and remove this dummy plate now because I know exactly my positioning of where I need
to nail.
Thanks Bo.
Now that I've nailed the architrave on both ends I can now come to the middle of the architrave
and nail it so it is still even with the reveal.
Now I've fitted the bottom architrave.
It's now time to cut for the top one.
We know that the window is square and level, so the top architrave is exactly the same
cut as the bottom architrave.
Just remember it's a mirror image of the bottom architrave to the top.
I've got Bo here holding the small piece of timber with the mortar on it on that end and
I'm about to nail this end off at the right height.
Now I can move to Bo's end and finish off that corner.
Now that we've fixed our top and bottom architrave it's now time to put the sides on.
So what we do is we measure down from the long point to the long point and we cut it
to that size.
So remember, it is important to measure both sides on the architraves because they could
be slightly out.
Now that I made sure that the architrave will fit, before we nail it, I'm going to put some
PVA glue on the corners.
This PVA glue will hold the corners in place for themselves.
Now we've got the glue on the corners and it's time to use our safety gear and nail
it away.
So now we've finished that side.
It's now the identical process on the other side.
And it's as easy as that.
Any DIYer can do it.
That's how you install an architrave.
