Floor Threshold Seal Fitting Instructions

Weather Stop garage door threshold seals are suitable for use with manual and automatic up-and-over, sectional, roller shutter and side hinged garage doors. The surface must be clean and free from dust, oil or grease. Where the surface is painted a wire brush should be used on the area where the threshold seal will be fitted to remove loose paint.

Important: This product is not suitable for loose concrete or gravel. Unsealed surfaces 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.

  1. Open the garage door and measure the overall width of the opening. Allow approximately 40mm (1 ½”) overhang at each end to allow the threshold seal to be notched back around the door frame or side tracks. Then cut the length to size.

  2. Position the threshold seal behind the door and, with a suitable marker, mark where the threshold seal should be notched back. This will allow the threshold seal to be positioned correctly behind the door and create a tight seal around the frame. Notch the seal on both ends with a hacksaw or sharp scissors to fit around the door frame or side tracks.

  3. From inside the garage, with the door closed, push the seal up to the back of the door with the hump touching the door, or as tight as it will go whilst still ensuring the door will close and lock in place. If necessary, notch ends of the threshold back further to create a tight seal. Mark along the back edge of the floor seal with a pencil or suitable marker.

  4. Open the door and mark a line along the front edge of the threshold seal. Remove the threshold seal and mark two parallel lines approximately 10mm inside the existing lines. Then mark a zigzag line in the middle of them.

  5. Before fitting the threshold seal, use a dry cloth to remove any dust or dirt from the bottom of the seal. Brush the floor thoroughly ensuring that it is clean and free from dust, debris, oil and grease.

    Cut off the end of the adhesive cartridge and also cut approx. 15mm (½”) from the end of the back nozzle using a hacksaw or sharp knife. Screw the black nozzle onto the adhesive cartridge, and apply the adhesive to the floor following the pencil lines created.

  6. Begin from one end. Place the threshold seal on top of the adhesive and press firmly downwards. Continue along the rest of the threshold seal, ensuring good contact at all points. Remove any excess adhesive from the sides with a clean cloth. Apply adhesive around the door frame or side tracks to ensure a watertight seal

Weather Stop garage door threshold seals are suitable for use with manual and automatic sectional doors, roller 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.

  1. Measure the distance between the outside edges of the garage door tracks. Cut the threshold seal to that length.

  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. This is the depth that needs to be cut out of the threshold seal to fit it around each of the door tracks.

  3. 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.

  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 (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.

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

  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. 10mm inside the existing lines. Then mark a zigzag line inside the parallel lines.

  7. Before fitting the threshold seal, use a dry cloth, to remove any dust, grease and dirt from the bottom of the threshold seal. Important: Brush the floor thoroughly ensuring that it is clean and free for dust, debris, oil and grease. Cut the end off the adhesive tube and also cut off approx. 15mm off the end of the adhesive nozzle using a hacksaw or sharp knife. Apply the adhesive to the floor following the marked lines. Note: Application temperature of the adhesive is +5º C to +25º C. It is recommended to keep the adhesive at room temperature prior to use.

  8. 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.

  9. Finally apply adhesive around door tracks to ensure a watertight seal.

  10. For doors with open side tracks, side blocks should be inserted into the space between the wall and the track to prevent water ingress. (Side blocks are available on the Weather Stop websites).

    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 Step Six.
    d) Seal around any edges as required
