Before installing your garage door threshold seal, make sure your floor is clean and free from dust, debris oil and grease. For painted floors, a wire brush should be used to remove loose paint.

Step 1:
Measure the distance between the outside edges of the garage door tracks, then use a hacksaw to cut the threshold seal to that length.

Step 2:
Position the threshold seal behind the door tracks and mark where it needs to be cut to fit securely around the door tracks. Measure the distance between the back of the door and the back edge of the door track.

Step 3:
Cut the threshold seal as required to fit around both of the door tracks. As an option, the offcut section can be used to fill in the gap inside the door track.

Step 4:
With the garage door closed, place the threshold seal in position and push up tight against the back of the door to create a tight seal. The garage door should close onto the front edge of the seal. If not, move the threshold seal back and recheck. There should not be any visible daylight.

Step 5:
With the threshold seal in position, mark along the back edge of the seal inside the garage.

Step 6:
Open the garage door and mark along the front edge of the seal. Remove the threshold seal from the floor and mark two parallel lines approx. 1/2" inside the existing lines, then mark a zigzag line inside the parallel lines.

Step 7:
Before fitting the threshold seal, use a dry cloth to remove any dust, grease or dirt from the bottom of the seal. Cut the end off the adhesive tube using a hacksaw or sharp knife then apply the adhesive to the floor using the marked lines.

Step 8:
Beginning from one end place the threshold seal on top of the adhesive and press down firmly ensuring good contact at all points. Remove any excess adhesive from the sides with a clean cloth.

Step 9:
Apply the adhesive around the door tracks to ensure a watertight seal.

Step 10 (optional):
For doors with open sidetracks, the side blocks that have been supplied should be inserted into the space between the wall and the track to prevent water ingress.

Once fitted, allow 24 hours before driving over the threshold. It is also recommended to test the installation using a bucket of water or hosepipe to check for water ingress.
