- Backer rod
- Wooden rod
- Cutting board

Get the materials
You will need construction adhesive (e.g. Unibond One for All), backer rod, a wooden rod, a cutter, a cutting board, a cartridge gun, a smoothing tool, a waste box, masking tape, sandpaper, and a bucket with water and soap.
Clean the parts
Before you seal your door frame, you need to clean the surface, otherwise the sealant will be less efficent. To do so, remove the old sealant, cutting it with a cutter. You can also get Silicone Remover that will make the job way easier. Then, don't forget to clean the gap with a paper towel.
Place the backer rod
Squeeze the backer rod into the gap between the door frame and the wooden construction. Position it two times deeper than the gap size itself. To make sure it's deep enough, you can adjust it with a wooden rod.
Apply masking tape
To protect the wall from the product, apply masking tape all around the door frame, along the gap.
Prepare the cartridge gun
Using a cartridge gun is useful, but you need to prepare the cartridge as well. Put the cartridge tip on top of the piece of wood to stabilize it and cut it with the cutter.
Prepare the cartridge nozzle
Now, screw the nozzle onto the cartridge and use the piece of wood to cut it. You should try to cut where you can have a hole of around 6mm, which is the recommendable diameter for the product application.
Apply the product
Now comes the fun part! Apply the construction adhesive (e.g. UniBond One for All) continously into the gap. Make sure to apply always the same amount along the door frame. Take your time, it's better to do it slower to assure a good application.
To flat the sealant, you should smooth it before it starts to skin over. To do so, use a smoothing tool, soaking it in the bucket with water and soap. Then, pass it over the sealant, applying the same pressure all along the frame.
