Garadry threshold seals are suitable for use with manual and automatic tilt doors, sectional doors, rolling doors and flex-a-doors.
The garage floor should be clean and free from dust, debris, oil and grease prior to fitting. For painted floors, a wire brush should be used to clean the area where the threshold seal is to be fitted to remove any loose paint.
Important: This product is not recommended for use on loose concrete or gravel surfaces. Unsealed concrete floors must be sealed prior to installation. (What is an unsealed floor? An unsealed floor is a floor with a loose or powdery finish)
Due to coiling in transport, the threshold seal should be laid flat on a clean surface so that it returns to its original shape.

The threshold seal should be fitted by a mature adult and due care and attention should be paid when stepping over the threshold seal.
Measure the distance between the outside edges of the garage door tracks. Cut the threshold seal to that length.
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. This is the depth that needs to be cut out of the threshold seal to fit it around each of the door tracks.
Cut the threshold seal as required to fit around both of the door tracks. (Optional) the off-cut section can be used to fill in the gap inside the door track.
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 (please ensure the garage door shuts correctly and locks with the seal in position – if it does not, then move the threshold back slightly and re-check. It is also advisable at this stage if you have an electrically operated door that the motor continues to operate normally).
If there is visible daylight, then the threshold seal may need to be cut back further around the door tracks to ensure a tight seal.
If there is a floor based alarm sensor, the threshold seal may need to be notched around this to ensure the alarm connection is not broken.
For the hump design thresholds, the hump will sit tight behind the door.
With the threshold seal in position, mark along the back edge of the seal inside the garage.
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. .” inside the existing lines. Then mark a zigzag line inside the parallel lines.
Before fitting the threshold seal, use a dry cloth, to remove any dust, grease and dirt from the bottom of the threshold seal.
Cut the end (approx. 1/2” or 1.25cm) off the adhesive tube using a hacksaw or sharp knife. Apply the adhesive to the floor following the marked lines.
Note: Application temperature of the adhesive is 40. F to 95. F. It is recommended to keep the adhesive at room temperature prior to use.
Important: Brush the floor thoroughly ensuring that it is clean and free from dust, debris, oil and grease.
Begin from one end. Place the threshold seal on top of the adhesive and press down firmly. Continue pressing down firmly along the rest of the length of the seal, ensuring good contact at all points. Remove any excess adhesive from the sides with a clean cloth.
Finally apply adhesive around door tracks to ensure a watertight seal.
Note: It may be necessary to adjust the garage door side locks or the electric garage door opener due to a change in the door’s position after installation. Please refer to your original manufacturer’s guidelines.
Important: Once fitted allow 24 hours before driving over the threshold. It is also recommended to test the installation using a bucket of water or a hosepipe to check for water ingress.
STEP TEN (OPTIONAL)
For doors with open side tracks, the side blocks that have been supplied should be inserted into the space between the wall and the track to prevent water ingress.
a) Measure the distance between the wall and the garage door track
b) Cut the side block to size using a sharp utility knife
c) Using the supplied adhesive, stick the side block to the concrete floor. Ensure that both the wall and the door track are coated in adhesive using the same method as
d) Seal around any edges as required
