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
