How to install architraves

Overview
Learn how to easily install an architrave around a window frame. We'll show you how to measure and cut the architraves, cut the mitre ends and how to attach the architraves to the window. Just follow our easy step-by-step guide.
Tools and materials
Steps
Measure the bottom architrave
First thing you need to do is measure the inside of the window reveal and add 5mm. The reveal length is measured from inside mitre point to inside mitre point. Transfer these measurements to your architrave timber.
Cut the architrave board
Use the mitre box to cut a 45 degree angle on the end of one of the architrave boards. Measure along and cut an opposite 45 degree mitre on the other end of the architrave.
Attach the architrave to the window
Place the bottom architrave on the wall. Place it 2.5mm down from the reveal. Check it is level. Use a dummy piece at the corner with a 45 degree angle to help position the architrave. Then nail it into place.
Repeat the process for the top architrave to mirror the bottom. Nail that into place using a dummy plate to check the position.
Measure the sides
Measure the sides from long point to long point of the top and bottom architraves. It's important to measure both sides of the architraves because their lengths could vary.
Cut the side architraves to length
Transfer your measurements and cut the side architraves to length. Remember to cut 45 degree angles at each end.
Attach the side architraves
Slot one architrave between the top and bottom architraves to make sure it fits. Take the side architrave and add some PVA glue to the corners. Then slot the architrave in again and nail it into place.

Health & Safety
Please make sure you use all equipment appropriately and safely when following the advice in these D.I.Y. videos. You need to be familiar with how to use equipment safely and follow the instructions that came with the equipment. If you are unsure, you may feel it is safest to consult an expert, such as the manufacturer or an expert Bunnings Team Member.
Grave health hazards are linked to asbestos, which may be in homes built up to 1990. Health hazards may result from exposure to lead-based paints in older materials and copper chromium arsenic (CCA) treated timber. For information on the dangers of asbestos, lead-based paint and CCA treated timber and tips for dealing with these materials contact your local council's Environmental Health Officer. You can also use a simple test kit from Bunnings to indicate the presence of lead-based paint.
